Detailed Description

To have an overview what the elements are, and how they fit into the entire database please refer to the Element Overview chapter. In these papers only the handler functions are explained in full details.

Element Overview

Applicable types of elements are enumerated in the API_ElemTypeID structure. The definition of an element is described in the API_Element structure, which is a union of all element types. All of the definitions begin with a common header structure named API_Elem_Head.

• The type.typeID field identifies the type of the element.
• The type.variationID field is an extension of type.typeID in case of API_ObjectID, API_LampID, API_WindowID, API_DoorID. It identifies the subcategory (e.g. Stair) of the element.
• The guid field gives a globally unique identifier of the element, which is constant through the whole life of the project. These values are automatically generated and there is no way to control which unique ID is assigned.
• The modiStamp field gives you a stamp to check if the element was modified.
• The guid and groupGuid fields contain the grouping information. The first one identifies the group which the given element belongs to. The second one identifies the root-parent group in case of nested groups.
• The floorInd field identifies the story that the element belongs to (not applicable to all element types).
• The layer field is the attribute index of the layer selected for the element (not applicable to all element types).
• The hasMemo field is a flag, which shows that the given element has additional data, described in the structure API_ElementMemo.
• The drwIndex field determines the drawing order of elements, and can be adjusted by the user or from the API with the Send to Back/_Bring to Front_ commands. Elements which have bigger drwIndex will be drawn later.

Every structure which describes a particular type of element (like API_WallType, API_LineType etc.) are logically separated into different parts.

• The first part is the header. It contains common information which is element type independent.
• The next part corresponds to the parameters which can be set in the tool setting dialog boxes or in the Info Box. They do not depend on the geometry, just describe general parameters like attributes, control flags and so on.
• The last part corresponds to the user clicks done while the element was placed on the floor plan. This part is a pure geometrical description.

Many element related functions use the API_Element structure on the parameter list. As a general rule, you have to fill the required fields in the union. Archicad parses the request based on the values, and passes the return parameters in the same structure. This is why most of the functions do not have the const directive in their prototypes.

---

Retrieving an element from the database

Please note that from API 11 we start to move away from the typeID/index identification towards a GUID-based identification. In API 12 the GUID way has precedence. From API 18 the GUID way is only available, typeID/index identification was removed.

Let's look at a simple example. Assume you are interested in getting the data of a given element of the database. In this case you should use a variable of type API_Element.

API_Element  element = {};
GSErrCode    err;
 
element.header.guid = GSGuid2APIGuid (GS::Guid ("EF7A21F7-F841-4030-B6DC-C1DC8DA2F1E6"));
 
err = ACAPI_Element_Get (&element);

The data of the wall is returned in the element.wall part of the union. You should check the hasMemo field in the returned header. If it is set you are informed that additional data is available for the element, such as gables and polygon nodes. Since producing this data may be a relatively a long conversion process, this information can be obtained with an additional function call.

GSErrCode       err;
API_ElementMemo memo = {};
 
err = ACAPI_Element_GetMemo (element.header.guid, &memo, APIMemoMask_All);

In this case, you have got all of the additional data related to the particular element. The memo structure is a collection of several handles and pointer (dynamic memory). If any is allocated (i.e. its value is not nullptr it contains data. If you do not need the data any more you are required to free the allocated memory blocks. The suggested way is the following:

ACAPI_DisposeElemMemoHdls (&memo);

If you use this function, it is ensured that all of the dynamic data will be freed, and also there will be no compatibility problems if your add-on is installed to a newer version of Archicad.

It is very important to examine the error codes returned by the API functions, and interpret the returned value.

It is usual that you want to go through the instances of a particular type of element in the database. The following example gives a good template to do that:

GS::Array<API_Guid> elemList;
GSErrCode err = ACAPI_Element_GetElemList (API_WallID, &elemList);
for (Int32 i = 0; i < elemList.GetSize () && err == NoError; ++i) {
    API_Element element = {};
    element.header.guid = elemList[i];
    if (ACAPI_Element_Get (&element) == NoError) {
        /* do what you want */
    }
}

A better and suggested way to set up such a loop is to use the element filter service of the API. It is common that you are interested in elements being on the active story only or being on a visible layer, or just for editable elements, and so on. If you call the ACAPI_Element_Get function in a loop, Archicad is requested to convert all of the elements to API form, even if you do not need them. This algorithm can be very slow.

In the next example you see a very effective, fast way to get the elements only you are interested in:

GS::Array<API_Guid> elemList;
ACAPI_Element_GetElemList (API_WallID, &elemList, APIFilt_OnActFloor);
for (GS::Array<API_Guid>::ConstIterator it = elemList.Enumerate (); it != nullptr; ++it) {
    API_Element element = {};
    element.header.guid = *it;
    if (ACAPI_Element_Get (&element) == NoError) {
        /* do what you want */
    }
}

You now see that the APIERR_DELETED return code is not checked, since all elements are filtered which do not meet your needs as well as the deleted ones.

You can also enumerate elements by drawing order and creation order with the [ACAPI_DrawOrder_DrawOrderGetNext and [AACAPI_DrawOrder_CreationOrderGetNext database functions respectively.

---

Creating an element

The element creation procedure is also fairly simple. All you have to do is to fill the appropriate part of the API_Element and optionally, the API_ElementMemo structure. The [ACAPIACAPI_Element_Create function does the following:

• It checks the data for possible inconsistency. If some problem is encountered it may be corrected automatically (like an invalid attribute reference) or an error code is generated.
• It ignores, for example, guid field in the header structure, because they are automatically generated. These values are returned to you in the appropriate field.
• The generated element is placed in the data structure.

It is very important that Archicad does not free any dynamic data structure you have allocated and passed to Archicad. They must be freed by your code.

An other important note is the following. Every data structure filled by you must be initialized to zero, because of forward compatibility. Fillers may be used in the later versions of the API, so if they are not initialized to zero the result may be unpredictable.

The template to create an element should be the following:

API_Element     element = {};
API_ElementMemo memo = {};
API_Guid        wallGuid;
GSErrCode       err;
 
element.header.type = API_WallID;
/* fill element.wall */
/* fill memo for polygonal walls */
 
err = ACAPI_Element_Create (&element, &memo);
 
wallGuid = element.header.guid;
 
ACAPI_DisposeElemMemoHdls (&memo);

Many elements refer to each other and these cross-references can be set up very easily. You just have to follow the general logic of Archicad, which means that referred elements must exist. For example first you create a wall, then windows are placed in it, and also you can assign associated labels.

You also have to do the same using the API functions. The [ACAPI_Element_Create function returns the guid of the created element, which can be used in references. If you want to place a window in the created wall, and assign a label do the following:

element = {};
element.header.type = API_WindowID;
 
element.window.owner = wallGuid;
/* set other parameters... */
 
err = ACAPI_Element_Create (&element, nullptr);
element = {};
element.header.type = API_LabelID;
 
element.label.parent = wallGuid;
/* set other parameters... */
 
err = ACAPI_Element_Create (&element, nullptr);

---

Controlling the selection

You can control the active selection also.

There are two basic type of selection methods in Archicad:

• The selection may be controlled by individually selected elements.
• The other possibility is to rely on the marquee area.

Both of them are supported by the API. The possible values of the active selection method are enumerated in the API_SelTypeID structure. The API_SelEmpty identifier means that nothing is selected in the current database in Archicad. The API_SelElems identifier corresponds to the first method when elements are individually selected. Other values identify that the selection is done by some kind of marquee shape.

In case of individually selected elements, Archicad returns all the elements which are selected. In the case of marquee based selection, only those elements will be returned which have an intersection with, or are within the marquee area.

The element selection procedure is very easy. You just have to call the ACAPI_Selection_Select function to select an individual element, or a group of elements. You have the possibility either to open a new selection, or append one more element to the actual selection.

---

Internal parts of an element: the API_Neig structure

Both the ACAPI_Selection_Select and ACAPI_Selection_Get functions use the API_Neig structure. This data structure makes possible to distinguish the internal parts of the elements.

You can see how smart the cursor is, when you touch one of the element's nodes or edges while moving it through the shape of a given element. All of these points or edges can be described by an API_Neig structure.

• The neigID field identifies the element type. Correspondence can be set up between the possible values of API_NeigID and the API_ElemTypeID structures; the first one is a sub-kind of the second one. Use the [APACAPI_Element_NeigToCoord function for conversion purposes.
• The guid field is the element guid.
• The inIndex field identifies the internal index of special point or edge.
• The flags field just gives information e.g. if the described point or edge belongs to a subcontour or the main contour of a polygonal element (API_NeigFlg_HoleSel).

Let's see an example. According to the roofs the special interests are organized into three subclasses. They are:

neigID	inIndex range	Description
APINeig_Roof	[1...n]	Identifies one of the vertices of the roof polygon. The inIndex value corresponds to the position of the vertex in the vertex array. The holeSel bit in the flags is not set if the point belongs to the main contour of the roof polygon.
APINeig_RoofOn	[1...n]	Identifies one of the edges of the roof polygon. The inIndex value corresponds to the position of the starting vertex in the vertex array. The holeSel bit in the flags is set if the edge belongs to a subcontour of the roof polygon.
APINeig_RBL	[1...2]	Identifies the reference line of the roof. The inIndex value 1 and 2 means the start and end point of it, respectively.

When you go through the selected elements, you get the information which point or edge was clicked by the mouse when the selection was made. The only useful information according to the selection is whether a whole polygonal element is selected or just one of its sub-contours.

If you search the API_Neig structure in the APIdefs_Elements.h file, you will see that it is used in many places.

It is used to give you information on which point was clicked in the input functions; see the [AACAPI_UserInput_GetPoint function.

The 3D model

Warning

Obsolete. The recommended way of accessing the 3D Model is now illustrated in the ModelAccess example.

The 3D representation of the actual database can be accessed through the API_Component3D structure.

Applicable types of elements are enumerated in the API_3DTypeID structure. The definition of a 3D component is described in the API_Component3D structure, which is in fact a union of all component types. All of the definitions begins with a common header structure, API_3D_Head.

• The typeID field identifies the type of the component.
• The index field gives the current database index of the given component. Note that this number is not constant for a particular element through the whole life of the project.

Before you try to understand how the 3D model corresponds to the API structures, please read carefully the Primitive Elements chapter in the GDL Reference Manual.

The 3D representation of a particular element is based on the API_BodyType structure. One element may hold one or more bodies to describe the 3D geometry. Generally a body is built up from a number of vertices, edges, polygons and normal vectors. This data structure gives you the number of the internal components as well as some status bits, surface properties and a global transformation matrix. You also get a reference to the parent element through an API_Elem_Head structure.

The 3D geometry itself is described by the API_PgonType, API_PedgType, API_EdgeType, API_VertType and API_VectType structures. They are documented in the GDL Reference Manual.

The 3D representation also owns a common pool of the surface materials. The polygon instances of the geometry description refer to these materials by indices. One surface definition is described by the API_UmatType structure. Surface materials may come from two sources. The list of materials contains all the global material attributes which are referenced by any polygon of the 3D geometry. Materials may be defined in GDL scripts also.

Elements placed with the light tool on the floor plan may contain light emissions, defined via GDL scripts. All of the light sources present in the 3D geometry are described with the API_LghtType structure.

---

Getting the whole 3D model

Warning

Obsolete. The recommended way of accessing the 3D Model is now illustrated in the ModelAccess example.

If you are interested in the whole 3D model that actually exists, you should use the following template:

API_Component3D   comp3D = {};
Int32             nBody, i;
GSErrCode         err;
 
err = ACAPI_3D_GetNum (API_BodyID, &nBody);
comp3D.header.typeID = API_BodyID;
for (i = 1; i <= nBody && err == NoError; i++) {
    comp3D.header.index = i;
    err = ACAPI_3D_GetComponent (&comp3D);
    if (err == NoError) {
        /* explode the body into pgon, vert etc... */
    }
    if (err == APIERR_DELETED)
        err = NoError;
}

It is very important to organize your algorithm on a loop based on the component API_BodyType for the following reasons:

• Body indices are continuous in all cases, others are not.
• The 3D model also can have data from deleted floor plan elements. They can be identified only through the deleted bodies.
• Floor plan elements which have the same geometry may share the primitives of the 3D representation data, but not the bodies. All the bodies contain a transformation matrix which transforms the referenced shared vertices and normal vectors to the right places and directions.

Once you have the definition of a body, you can set up inner loops to go through the primitives you are interested in. In the API_BodyType record you get the number of all internal components. Indices should start from 1.

The light and material components can be obtained in their own loops, because they are global (not body relative) components of the 3D model.

It is very important, that you get the data of the 3D model of Archicad that actually exists. This data is often not consistent with the floor plan elements. The update mechanism of the 3D window depends on many things, such as the switches in the preferences dialogs. As a general rule, you get the model which can be seen in the 3D window, if you use the above template.

---

Getting the 3D representation of a particular element

You also have the possibility to get the 3D representation of any particular floor plan element you are interested for. The basic mechanism is the same as in the previous example. The only difference is that you need the information which bodies belong to the given element.

Bodies assigned to a specific floor plan element can be obtained with the function ACAPI_ModelAccess_Get3DInfo. This function fills an API_ElemInfo3D structure to pass the index range of the main 3D data containers.

• The fbody and lbody field defines the first and last body indices. This range of indices should be used to get the body definitions.
• The flight and llight fields defines the first and last light indices. The 3D GDL script of objects may contain the LIGHT commands which determines that the given element has light emission. This data can be obtained through the API_LghtType, based on these indices.

Important note: in this way the data you get is independent from the actually existing 3D model of Archicad. If the existing data is not consistent, Archicad converts the given element to 3D again to ensure the right result. As a general rule, you get the model which is fully synchronized to the actual floor plan data.

You should choose between the above mentioned ways to get the 3D model very carefully.

If you need consistent data you should choose the second way, setting up a loop which goes through the floor plan elements you are interested for. In this case you can get the 3D model element by element.

You often have to choose the first method. For example, if your add-on is called from the "Save As 3D" dialog, the data user wants to save is the data actually can be seen in the 3D window.

API_WallReferenceLineLocationID

enum API_WallReferenceLineLocationID

Distinguishes among the different wall reference line locations.

Remarks

These constants determine the location of the reference line in the wall. This - along with the new flipped member in API_WallType - replace the old API_WallDirID, and allow you to exactly position the reference line, instead of coding both this position and the 'flippedness' of the wall into one member. Imagine a horizontal unflipped composite wall drawn from left to right (as shown in the Composite Settings dialog): outside is the top, inside is the bottom.

Wall reference line location

Only composite walls may have a core-related reference line location; polygonal and complex walls always use @ref APIWallRefLine_Outside. Profiled walls don't use this member; their reference line always goes through their origin. When its value is APIWallRefLine_Center or @ref APIWallRefLine_CoreCenter, you cannot specify an offset in the API_WallType structure. The new offsetFromOutside output only member in API_WallType tells you the distance between the 'top' of the wall (as shown in the Composite Settings dialog) and the reference line's position.

API_LabelID	beside the setting parameters the following fields can be edited: begC, midC, endC, u.text (the same as API_TextID), u.symbol (the same as API_ObjectID); for textual label the content and the style of the text can also be modified (textContent, paragraphs memo); an associative Label cannot be made independent, and an independent Label cannot be made associative.
API_ZoneID	beside the setting parameters the following fields can be edited: libInd, pos and the polygon of the zone (coords, pends, parcs, vertexIDs memo handles)
API_HatchID	beside the setting parameters the following fields can be edited: note and the polygon of the hatch (coords, pends, parcs, vertexIDs memo handles)

API_SectElemID	after modifying the parent element on the floor plan database, calling ACAPI_Element_Change for the section symbol element on the section database rebuilds the image of the modified element in the section window (use this to avoid unnecessary ACAPI_View_Rebuild and ACAPI_Database_RebuildCurrentDatabase calls). The function returns APIERR_DELETED if the parent element has been deleted or got out of the scope of the section; otherwise it gives back the new index of the refreshed section element.
API_MorphID	in some cases changing the tranmat field effects the body points themselves and vice versa; the resulting body will be correct, but getting the tranmat field after setting might result different values inside
API_HotlinkID	the type, and hotlinkGroupGuid fields can not be changed.
API_ExternalElemID	beside the setting parameters in case of non-hierarchical external elements params memos can also be modified

You can modify more elements at once with a single call of the ACAPI_Element_ChangeMore function.

Example

GSErrCode FlipWall (const API_Guid& wallGuid)
{
    API_Element element {}, mask;
    API_Coord   c1, c2;
    GSErrCode   err = NoError;
 
    element.header.guid = wallGuid;
    err = ACAPI_Element_Get (&element);
    if (err != NoError)
        return err;
 
    c1 = element.wall.begC;
    c2 = element.wall.endC;
 
    if (err == NoError) {
        ACAPI_ELEMENT_MASK_CLEAR (mask);
        ACAPI_ELEMENT_MASK_SET (mask, API_WallType, begC);
        ACAPI_ELEMENT_MASK_SET (mask, API_WallType, endC);
 
        element.wall.begC = c2;
        element.wall.endC = c1;
 
        err = ACAPI_Element_Change (&element, &mask, nullptr, 0, true);
    }
 
    return err;
}

ACAPI_Element_ChangeContent()

GSErrCode ACAPI_Element_ChangeContent

(

API_ContentPars *

contentPars

)

Change the content of a text or a textual label element.

Parameters

contentPars

[in/out] Parameters of the element and contents.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The input parameters are not given correctly.
• APIERR_REFUSEDPAR - The passed element is not a text or a textual label.
• APIERR_PAROVERLAP - The range overlaps two or more paragraphs.
• APIERR_PAROVERFLOW - The beginning position (from) run over the content length.
• APIERR_MEMFULL - Not enough memory.

Remarks

This function is used to modify the content of a multistyle text or textual label. The styles of the runs won't be lost. The new content piece will pick up the style (font, size, faceBits...) of the character on the from position in the original content. The content member of API_ContentPars should not contain line end characters and ranges may not overlap paragraphs. The another way to change the content is using ACAPI_Element_Change function. With it you can set the style of the text also by passing textContent and paragraphs handles in API_ElementMemo structure. Don't forget to free the allocated memory blocks. This function is a non-undoable data structure modifier function. See more details on this topic at Command Overview.

Example

Changing the content of a text element:

The original element

GSErrCode err = NoError;
 
err = ACAPI_CallUndoableCommand ("Change the content of a text element",
    [&] () -> GSErrCode {
 
        API_ContentPars contPars;
        Int32 numOfChanges = 2;
 
        contPars.head.type.typeID   = API_TextID;
        contPars.from               = reinterpret_cast<Int32 *> (BMAllocatePtr (numOfChanges * sizeof (Int32), ALLOCATE_CLEAR, 0));
        contPars.range              = reinterpret_cast<Int32 *> (BMAllocatePtr (numOfChanges * sizeof (Int32), ALLOCATE_CLEAR, 0));
        contPars.content            = BMAllocatePtr (256 * sizeof (char), ALLOCATE_CLEAR, 0);
        contPars.separator          = reinterpret_cast<Int32 *> (BMAllocatePtr (numOfChanges * sizeof (Int32), ALLOCATE_CLEAR, 0));
 
        if (contPars.from == nullptr || contPars.range == nullptr || contPars.content == nullptr || contPars.separator == nullptr)
            return APIERR_MEMFULL;
 
        contPars.from[0]    = 5;    // byte position
        contPars.range[0]   = 16;   // byte number
        contPars.from[1]    = 28;
        contPars.range[1]   = 13;
        CHCopyC ("raw was modified too", contPars.content);
        contPars.separator[0] = 16; // byte offset
        contPars.separator[1] = 32;
 
        GSErrCode err1 = ACAPI_Element_ChangeContent (&contPars);
 
        BMKillPtr (reinterpret_cast<GSPtr *> (&contPars.from));
        BMKillPtr (reinterpret_cast<GSPtr *> (&contPars.range));
        BMKillPtr (reinterpret_cast<GSPtr *> (&contPars.content));
        BMKillPtr (reinterpret_cast<GSPtr *> (&contPars.separator));
 
        return err1;
    });
 
return err;

The result element

ACAPI_Element_ChangeDefaults()

GSErrCode ACAPI_Element_ChangeDefaults	(	API_Element *	element,
		API_ElementMemo *	memo,
		const API_Element *	mask )

Changes the default parameters of an element.

Parameters

element	[in] Contains the general parameters to which you would like to change the defaults.
memo	[in][ Contains the special parameters to which you would like to change the defaults.
mask	[in] Contains a mask that specifies which parameters you would like to change. The memo fields are always used when they contain valid data.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed parameter is nullptr ; element
• APIERR_BADID - The element type is invalid, or the element type is not supported by the server application
• APIERR_REFUSEDCMD - The element type is not a valid target for the operation; API_SectElemID
• APIERR_MEMFULL - Not enough memory to complete the operation

Remarks

This function is used to change the actual default settings for an element type. Only those parameters are changed where the corresponding field in the mask is not 0. The requested type is identified by the type field of the header. The memo parameter is used only in the case of API_WindowID, API_DoorID, API_ObjectID, API_LampID, API_RoomID, API_LabelID, API_PictureID and API_ExternalElemID. For library part-based elements, if memo is set to nullptr, the default parameters of the originating library part are used, otherwise the values are taken from the params field of memo. To retrieve the actual settings defaults use the ACAPI_Element_GetDefaults function. Only those parameters are required to fill in the element argument, which are marked to be changed. There are macros to set up the mask values correctly. They are:

• ACAPI_ELEMENT_MASK_CLEAR - Clear all the flags in the mask
• ACAPI_ELEMENT_MASK_SETFULL - Set all the flags in the mask
• ACAPI_ELEMENT_MASK_SET - Set only one flag in the mask according to one element parameter
• ACAPI_ELEMENT_MASK_CHECK - Check the mask for one element parameter Don't forget to call ACAPI_DisposeElemMemoHdls to dispose of the passed handles. Note, that the ACAPI_SetDefaults function became obsolete; it was the solution in API 1.3. In order to change the default settings of markered element types (API_WindowType, API_DoorType, API_CutPlaneType, API_ChangeMarkerType, API_DetailType, API_WorksheetType and API_ExternalElemType) use the ACAPI_Element_ChangeDefaultsExt function instead.

Example

API_Element element {}, mask {};
GSErrCode   err;
 
element.header.type = API_WallID;
err = ACAPI_Element_GetDefaults (&element, nullptr);
 
if (err == NoError) {
    ACAPI_ELEMENT_MASK_CLEAR (mask);
    ACAPI_ELEMENT_MASK_SET (mask, API_Elem_Head, layer);
    element.header.layer = ACAPI_CreateAttributeIndex (27);
    err = ACAPI_Element_ChangeDefaults (&element, nullptr, &mask);
}

ACAPI_Element_ChangeDefaultsExt()

GSErrCode ACAPI_Element_ChangeDefaultsExt	(	API_Element *	element,
		API_ElementMemo *	memo,
		const API_Element *	mask,
		UInt32	nSubElems,
		API_SubElement *	subElems )

Changes the default parameters of the Window, Door, Section, Elevation, Interior Elevation, ChangeMarker, Detail, Worksheet, or Stair default element and its marker(s). You are able to change Curtain Wall and its subelem default settings also via this function.

Archicad 25

Parameters

element	[in] Contains the general parameters to which you would like to change the defaults. The element->header.type can be API_WindowID, API_DoorID, API_CutPlaneID, API_ElevationID, API_InteriorElevationID, API_ChangeMarkerID, API_DetailID, API_WorksheetID, API_CurtainWallID, API_CurtainWallPanelID, API_CurtainWallFrameID, API_CurtainWallJunctionID, API_CurtainWallAccessoryID, API_StairID or API_ExternalElemID.
memo	[in][ Contains the special parameters to which you would like to change the defaults.
mask	[in] Contains a mask that specifies which parameters you would like to change. The memo fields are always used when they contain valid data.
nSubElems	[in] The number of subelems passed (0-3)
subElems	[in] Usually the first marker contains the general marker parameters to which you would like to change the defaults. If this parameter is not nullptr then the header.type must be API_ObjectID. The mask specifies which parameters of the marker you would like to change. These fields are always used when they contain valid data. The second marker element is the Story Handle Marker where applicable. The third marker element is the common marker of the interior elevation element.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed element parameter is nullptr.
• APIERR_BADID - The element type should be API_WindowID, API_DoorID, API_CutPlaneID, API_ElevationID, API_InteriorElevationID, API_ChangeMarkerID, API_DetailID, API_WorksheetID, API_CurtainWallID, API_CurtainWallPanelID, API_CurtainWallFrameID, API_CurtainWallJunctionID, API_CurtainWallAccessoryID, API_StairID or API_ExternalElemID.
• APIERR_MEMFULL - Not enough memory to complete the operation.

Remarks

This function is used to change the actual default settings for a Window, Door, Section, Elevation, Interior elevation, ChangeMarker, Detail or Worksheet element type, as an alternative of ACAPI_Element_ChangeDefaults. The marker parameters are optional, pass nullptr to keep them unchanged. For the detailed interpretation of the parameters refer to the ACAPI_Element_ChangeExt function. Only those parameters are changed where the corresponding field in the mask is not 0. The requested type is identified by the type field of the header. The memo parameter is used only in the case of API_WindowID and API_DoorID. For library part-based elements, if memo is set to nullptr, the default parameters of the originating library part are used, otherwise the values are taken from the params field of memo. To retrieve the actual settings defaults use the ACAPI_Element_GetDefaultsExt function. Only those parameters are required to fill in the element argument, which are marked to be changed. There are macros to set up the mask values correctly. They are:

Mask function	Behavior
ACAPI_ELEMENT_MASK_CLEAR	Clear all the flags in the mask
ACAPI_ELEMENT_MASK_SETFULL	Set all the flags in the mask
ACAPI_ELEMENT_MASK_SET	Set only one flag in the mask according to one element parameter
ACAPI_ELEMENT_MASK_CHECK	Check the mask for one element parameter

Remember to call ACAPI_DisposeElemMemoHdls to dispose of the passed handles.

ACAPI_Element_ChangeElementInfoString()

GSErrCode ACAPI_Element_ChangeElementInfoString	(	const API_Guid *	elementGuid,
		const GS::UniString *	infoString )

Changes the compound info string of the given element.

Parameters

element	[in/out] Reference to the element to be modified, filled with the appropriate new parameters
mask	[in] Optional parameter for masking the relevant fields of element
memo	[in] The memo data to be changed. Optional parameter, can be nullptr
memoMask	[in] Specifies the relevant parts of the memo parameter. You can use a special mask value (ACAPI_ELEMENT_CHANGEEXT_ALLSEGMENTS) to change all segment of an interior elevation element.

subElems	[in] Contains the markers (default marker, story handle marker, interior elevation common marker) to be modified.
withdel	[in] Delete the original instance of the element, or keep it and create a new one
subIndex	[in] The index of the section segment to be modified (for interior elevations only). The value is between 0 and the (number of segments - 1).

Returns

• NoError - The function has completed with success.
• APIERR_BADDATABASE - The current database should be floor plan, section/elevation, detail or worksheet.
• APIERR_BADPARS - The passed element parameter is nullptr,

Remarks

This function is an extension of ACAPI_Element_Change to modify elements with their linked sub-elements. With this function not only the setting type parameters of an element can be modified, but geometry data too. Unlike ACAPI_Element_ChangeParameters and ACAPI_Element_Edit, it works only on one element at a time. On return the guid field of the element and elementMarker header is filled in. Element connections and dimension chains are updated automatically. Do not forget to call ACAPI_DisposeElemMemoHdls to dispose the memo handles when they are not needed any more. The following element types are supported:

element	memo	elementMarker	memoMarker	elementMarker2	memoMarker2
API_WindowType API_DoorType	addpar	window/door marker object	marker object parameters	-	-
API_CutPlaneType	cutplane coordinates	section marker object on floorplan	section marker object parameters	story handle marker object on section	story handle marker object parameters
API_ElevationType	elevation coordinates	elevation marker object on floorplan	elevation marker object parameters	story handle marker object on section	story handle marker object parameters
API_ChangeMarkerType	polygon data (optional)	ChangeMarker marker object	marker object parameters	-	-
API_WindowType API_DoorType	addpar	window/door marker object	marker object parameters	-	-

		const API_ElementMemo *	memo )

Changes the memo part of certain element types.

Parameters

guid	[in] Guid of the element.
mask	[in] Specifies which part of a memo should be changed. Currently only APIMemoMask_Polygon is supported.

Returns

• NoError - The function has completed with success.
• APIERR_BADID - You called the function for element types other then slabs or roofs.
• APIERR_BADPARS - You called the function with a mask value other than APIMemoMask_Polygon, or you specified wrong parameters.

Remarks

This function is used to change the memo part of certain element types. Currently you can change only the polygon data of polygonal elements. It is recommended to use the ACAPI_Element_Change function instead.

ACAPI_Element_ChangeMore()

GSErrCode ACAPI_Element_ChangeMore	(	GS::Array< API_Guid > &	elemGuids,

ACAPI_Element_ChangeMorphEdgeType()

GSErrCode ACAPI_Element_ChangeMorphEdgeType	(	const API_Guid &	elemID,
		API_MorphEdgeTypeID	edgeType )

Modifies a morph element's edge type in the current database.

Parameters

elemID	[in] GUID of the morph element to be modified
edgeType	[in] Edge type ID

Returns

• NoError - The function has completed with success.

  {
      API_Element element {}, mask;
      API_Coord   c1, c2;
      GSErrCode   err = NoError;

      err = ACAPI_Element_Get (&element);
      if (err != NoError)
          return err;
   
      c1 = element.wall.begC;
      c2 = element.wall.endC;
   
      if (err == NoError) {

          ACAPI_ELEMENT_MASK_SET (mask, API_WallType, begC);
          ACAPI_ELEMENT_MASK_SET (mask, API_WallType, endC);
   
          element.wall.begC = c2;
          element.wall.endC = c1;
   
          err = ACAPI_Element_Change (&element, &mask, nullptr, 0, true);
      }
   
      return err;
  }

ACAPI_Element_ChangeParameters()

GSErrCode ACAPI_Element_ChangeParameters	(	const GS::Array< API_Guid > &	elemGuids,
		const API_Element *	defPars,
		const API_ElementMemo *	defMemo,

Changes the parameters of a number of elements.

Parameters

elemGuids	[in] Identifies the element(s).
defPars	[in] The parameters of the new element.
defMemo	[in] The memo of the new element. (Only if needed.)
mask	[in] The mask of the new element.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - defPars is nullptr
• APIERR_BADDATABASE - The current database is not proper for the operation
• APIERR_MEMFULL - Not enough memory to complete the operation

Remarks

You can use this function to change the settings parameters of a number of elements, identified by elemGuids. If elemGuids is empty, then this function works on the selection. Only those elements are affected whose type is the same that passed in the defPars argument. Elements which are not allowed for edit for some reason, are ignored. Such cases can be:

• it is locked,
• it is on a locked layer,
• it is part of a group, and suspend group is OFF
• it is not in the users workspace, etc. This function can only be used to change the settings-type parameters of elements, but not their geometric parameters. Only those parameters are affected which are marked in the mask argument. Such elements which refer to Library Parts, the params handle from the memo is interpreted. If it is nullptr, nothing will happen. If it is passed, the actual parameter list will be changed. Refer to the ACAPI_Element_Change and the ACAPI_Element_ChangeDefaults functions, which work similarly. The following notes are absolutely important:
• the list of target elements will be automatically extended by the other group members; if there are a group member in the set, and suspend group is OFF
• all the edited elements keep their unique ID
• all the inter-element links will be adjusted; including dimensioning also, Do not forget to call ACAPI_DisposeElemMemoHdls to dispose of the handles when you're finished.

ACAPI_ELEMENT_COMPOSITES_QUANTITY_MASK_CLEAR()

void ACAPI_ELEMENT_COMPOSITES_QUANTITY_MASK_CLEAR ( API_QuantitiesMask & mask )

inline

		API_ElementMemo *	memo )

Places a new element into current database.

Parameters

element	[in/out] The desired element will be created in the pointed structure. The element->header.type must specify the type of the element to be created.
memo	[in] The memo field of the desired element will be created from the pointed structure (if the memo field is needed).

Returns

• NoError - The function has completed with success.
• APIERR_BADDATABASE - The current database is not proper for the operation.
• APIERR_BADPARS - The passed parameter is nullptr; element
• APIERR_BADID - The element type is invalid, or the element type is not supported by the server application

• APIERR_INVALFLOOR - The element->header.floorInd parameter is out of range.
• APIERR_IRREGULARPOLY - Input polygon or polyline is irregular.

Remarks

The type of the element to be created is defined by type in the element header. On return, the guid field of the header is filled in. Don't forget to call ACAPI_DisposeElemMemoHdls to dispose the handles when you're done. The meaning of the different parameters is explained in the table below:

API_DrawingID	optional (polygon, drawing data)
API_CutPlaneID	required	The cutplane coordinates are required. See also ACAPI_Element_CreateExt.
API_ChangeMarkerID	optional (polygon)	See also ACAPI_Element_CreateExt.
API_DetailID API_WorksheetID	optional (polygon)	See also ACAPI_Element_CreateExt.
API_CameraID	optional (linklist)	Optional for panoramic cameras only.
API_CamSetID
API_SectElemID		This type of element cannot be created.
API_StairID	required (polyline)
API_RailingID	required (polyline)

The creation process for elements follows the same process as the one you use for creating elements graphically in Archicad. This means for example, that you have to create a wall for windows and doors, etc. The API always checks for the presence of the necessary information, and returns with an error code if something is missing. The created element may be redirected into the 2D binary section of a Library Part. Refer to the ACAPI_LibraryPart_SetUpSect_2DDrawHdl function for details. In these case no information is returned, what indices, guids were generated. In this environment only 2D drawing elements can be generated. The element also can be clipped by a clipping region. Refer to the ACAPI_Database_StartClippingSession function for details. In these case no information is returned, what indices, guids were generated, since more parts may be generated.

ACAPI_Element_CreateExt()

GSErrCode ACAPI_Element_CreateExt	(	API_Element *	element,
		API_ElementMemo *	memo,
		UInt32	nSubElems,
		API_SubElement *	subElems )

Places a new Window, Door, Skylight, Section, Elevation, Interior Elevation, ChangeMarker, Detail, or Worksheet element with the specified marker into the current database.

Since

Archicad 25

Parameters

element	[in/out] The desired element will be created in the pointed structure. The element->header.type must specify the type of the element to be created. It can be API_WindowID, API_DoorID, API_CutPlaneID, API_ElevationID, API_InteriorElevationID, API_ChangeMarkerID, API_DetailID, API_WorksheetID, API_CurtainWallID or API_StairID.
memo	[in] The memo field of the desired element will be created from the pointed structure (if the memo field is needed).
nSubElems	[in] The number of subelems passed.
subElems	[in] Subelem / marker related information.

Returns

• NoError - The function has completed with success.
• APIERR_BADDATABASE - The current database is not proper for the operation.
• APIERR_BADPARS - The element parameter is nullptr, or the element type is invalid, or the element type is not supported by the server application. The elementMarker->header.type is not API_ObjectID.
• APIERR_REFUSEDPAR - The element->header.type parameter was incorrect. It might happen if you want to create something in a window not capable to display it, for example a cut plane in a section window.
• APIERR_INVALFLOOR - The element->header.floorInd parameter is out of range.

Remarks

The type of the element to be created is defined by type in the element header. On return, the guid field of the header is filled in. Don't forget to call ACAPI_DisposeElemMemoHdls to dispose the handles when you don't need them any more. The meaning of the different parameters is explained in the table below:

element	memo	elementMarker	memoMarker	elementMarker2	memoMarker2
API_WindowType API_DoorType	addpar	window/door marker object	marker object parameters	-	-
API_SkylightType	addpar	window/door marker object	marker object parameters	-	-
API_CutPlaneType	cutplane coordinates	section marker object on floorplan	section marker object parameters	story handle marker object on section	story handle marker object parameters
API_ChangeMarkerType	polygon data (optional)	ChangeMarker marker object	marker object parameters	-	-
API_DetailType API_WorksheetType	polygon data (optional)	detail drawing/worksheet marker object	marker object parameters	-	-

ACAPI_Element_Decompose()

GSErrCode ACAPI_Element_Decompose	(	const API_Guid &	elemGuid,
		API_ElementDecomposerInterface *	elementDecomposer )

Enumerates the planes of a Multi-plane Roof.

Parameters

elemGuid	[in] Identifier of the element to be decomposed. Currently this must be a PolyRoof element.
elementDecomposer	[in] Interface pointer to an object implemented by the caller to be used during the decomposition.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The elementDecomposer pointer is nullptr or the element specified with elemGuid is not PolyRoof type.
• APIERR_BADID - The elemGuid parameter does not identify a valid element.

Remarks

Use this function to enumerate the planes of a Multi-plane Roof as a set of Single-plane API_RoofType elements. First you need to implement a derived class of API_ElementDecomposerInterface. An object instance of this class should be passed to ACAPI_Element_Decompose to be called back by its GeneratePartElement method.

Example

class PolyRoofConverter : public API_ElementDecomposerInterface {
public:
    PolyRoofConverter (const API_Guid& polyRoofGuid);
    virtual GSErrCode   GeneratePartElement (const API_Guid& guid, const API_ElemPartId& partId,
                                             const API_Element& partElem, const API_ElementMemo& partMemo);
};
 
// Call decomposition for a given Roof element:
void DecomposeRoof (const API_Guid& roofGuid)
{
    API_Element element {};
    element.header.guid = roofGuid;
 
    GSErrCode err = ACAPI_Element_Get (&element);
    if (err == NoError && element.roof.roofClass == API_PolyRoofID) {
        PolyRoofConverter polyRoofConverter (element.header.guid);
        err = ACAPI_Element_Decompose (element.header.guid, &polyRoofConverter);
    }
}

ACAPI_Element_Delete()

GSErrCode ACAPI_Element_Delete

(

const GS::Array< API_Guid > &

elemGuids

)

Deletes a number of elements.

Parameters

elemGuids

[in] This parameter identifies the elements to be deleted.

Returns

• NoError - The function has completed with success.
• APIERR_BADDATABASE - The current database is not proper for the operation.
• APIERR_MEMFULL - not enough memory to complete the operation
• APIERR_NOTMINE - The operation attempted to delete an element that belongs to another user. Likely to occur in teamwork mode.

Remarks

You can use this function to delete elements identified by elemGuids. To delete the selected elements use ACAPI_Element_DeleteSelected function. In the case there is at least one element which are not allowed to delete for some reason, the whole command is terminated. Such cases can be:

• it is locked,
• it is on a locked layer,
• it is part of a group, and suspend group is OFF
• it is a subelement of a composite element (Curtain Wall, Stair, or Railing)
• it is not in the users workspace, etc. The following notes are absolutely important:
• the list of target elements will be automatically extended by the other group members; if there are a group member in the set, and suspend group is OFF
• all the linked elements will be deleted; associative labels, dimensions etc. Note that this function is working on the Section/Elevation databases also, which may have references to the plan database; they called virtual symbols identified by the API_SectElemID element type. From Archicad 6.50 R2/V2 these elements can be deleted directly from the section database, with the limitation that the section window must be the front window.

Example

GSErrCode Do_DeleteSelectedWalls ()
{
    return ACAPI_CallUndoableCommand ("Delete selected walls",
        [&] () -> GSErrCode {
            API_SelectionInfo   selectionInfo;

• APIERR_MEMFULL - not enough memory to complete the operation
• APIERR_NOTMINE - The operation attempted to delete an element that belongs to another user. Likely to occur in teamwork mode.

Remarks

You can use this function to delete selected elements. To delete specific elements use ACAPI_Element_Delete function. In the case there is at least one element which are not allowed to delete for some reason, the whole command is terminated. Such cases can be:

• it is locked,
• it is on a locked layer,
• it is part of a group, and suspend group is OFF
• it is a subelement of a composite element (Curtain Wall, Stair, or Railing)
• it is not in the users workspace, etc. The following notes are absolutely important:

            }
 
            return ACAPI_Element_Delete (wallGuids);
        });
}

ACAPI_Element_DetachObserver()

GSErrCode ACAPI_Element_DetachObserver

const API_Guid &

elemGuid

)

Detaches the observer from the given element.

Parameters

elemGuid

[in] Identifies the element to detach the observer from.

• NoError - The function has completed with success.
• APIERR_BADID - The referenced element cannot be found in the database.

ACAPI_Element_DrawElement()

GSErrCode ACAPI_Element_DrawElement	(	API_Elem_Head *	elem_Head,
		UInt32	mask )

Shows/draws an existing element.

Parameters

elem_Head	identifies the element to draw/show
mask	[in] Element mask (from floor plan).

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - elemHead is nullptr
• APIERR_BADID - The element is not present in the Archicad database.
• APIERR_DELETED - The element is deleted.

Remarks

This function is used to draw/show an element identified by its element header on the floor plan or in the section or detail window. You should fill the guid field.

ACAPI_Element_Edit()

GSErrCode ACAPI_Element_Edit	(	GS::Array< API_Neig > *	elemNeigs,
		const API_EditPars &	pars )

Transforms a set of elements.

Parameters

elemNeigs	[in-out] An Array of API_Neig objects which enables you to work not only on an element as a whole, but on its internal parts too.
pars	[in] The details of the editing operation.

Returns

• NoError - The function has completed with success.
• APIERR_BADDATABASE - The current database is not proper for the operation.
• APIERR_BADID - The element guid is invalid.
• APIERR_DELETED - The element does not exist in the database
• APIERR_MEMFULL - Not enough memory to complete the operation
• APIERR_REFUSEDPAR - The edit parameters are incorrect.
• APIERR_BADPARS - The edit parameters are incorrect.

Remarks

This function transforms a set of elements with the parameters passed in the API_EditPars structure. These parameters identify both the operation code (drag, rotate, mirror...) and the transformation parameters. If elemNeigs is nullptr or empty, then this function works on the selection; otherwise the set of elements passed will be the target. What elements are transformed in the last case? The elemNeigs array is an API_Neig list which enables you to work on not just a whole element, but on its internal parts as well. If you pass for example a neig to a slab hole, only the given hole will be transformed, without touching the base contour of the element. Elements which cannot be edited for some reason are ignored. Such causes can be:

• it is locked,
• it is on a locked layer,
• it is part of a group, and suspend groups is OFF
• it is not in the users workspace, etc. The following notes are absolutely important:
• the list of target elements will be automatically extended with the other group members; if there is a group member in the set and suspend groups is OFF
• all the edited elements keep their unique ID
• all the inter-element links will be adjusted; including dimensioning also The new element's GUID will be returned for each edited element in the guid field. Note that this function is working on Section/Elevation databases also, which may have references to the plan database; they called virtual symbols identified by the API_SectElemID element type. From Archicad 6.50 R2/V2 these elements can be edited directly in the section database, with the limitation that the section window must be the front window. You can also change the geometry data of an element with the ACAPI_Element_Change function.

ACAPI_Element_Elem2UIPriority()

GSErrCode ACAPI_Element_Elem2UIPriority	(	GS::Int32 *	elemPriority,
		GS::Int32 *	uiPriority )

Returns user interface priority for a building material connection priority.

elemType	The element type.
neigID	One neig ID for that element type.

Returns

• NoError - The function has completed with success.

Remarks

This function return a neig ID (a special point) for the given element type. This is useful in some situations, for example element selection, where you have to pass the array of neig IDs of the elements you want to select, but it is not important, which point of the element is given. Note that the element type? neig ID mapping is not a one-to-one, but a one-to-many mapping.

ACAPI_Element_Filter()

bool ACAPI_Element_Filter	(	const API_Guid &	guid,
		API_ElemFilterFlags	filterBits,
		API_ElemVariationID	variationID = APIVarId_Generic,

variationID	[in] Optional variation ID for objects. Used in combination with APIFilt_IsOfVariation. The default value is APIVarId_Generic.
renovationFilterGuid	[in] Optional global unique identifier of the renovation filter. Used in combination with APIFilt_IsVisibleByRenovation. The default value is APINULLGuid.

Returns

• true - The given element (defined by guid) matches the criteria defined by filterbits
• false - The referenced element does not pass the criteria

Remarks

Note that the 3D visibility of GDL-based elements can also be modified through GDL parameters which work independently from the element settings. Due to this there may be cases where the ACAPI_Element_Filter function shows that an elem is visible on 3D, but its GDL script hides it on 3D-based views. Returns true, if the given element matches the criteria defined by filterbits :

filterbits value	Checks whether the element	Concerned elements
APIFilt_None	not filtered
APIFilt_IsEditable	is not on a locked/deleted/invisible layer	all (for windows, doors and skylights this tests the layer of the owner element)
APIFilt_OnVisLayer	is on a visible layer	all (for windows, doors and skylights this tests the layer of the owner element)
APIFilt_OnActFloor	is on the active floor	all (always true for cut planes and groups)
APIFilt_In3D	has 3D representation	API_WallID, API_ColumnID, API_BeamID, API_WindowID, API_DoorID, API_SkylightID, API_ObjectID, API_LampID, API_SlabID, API_RoofID, API_MeshID, API_ShellID, API_CurtainWallID, API_MorphID
APIFilt_InMyWorkspace	is in my workspace (in Teamwork mode)	all element types
APIFilt_IsIndependent	is independent (not a sub elem)	API_ObjectID, API_TextID
APIFilt_OnActLayout	is on the active layout	drawing type elements
APIFilt_InCroppedView	is visible inside the cropped part of a drawing database	drawing type elements
APIFilt_IsOfVariation	tells if the given element has the variation ID passed in the variationID parameter.	object type elements
APIFilt_FromFloorplan	additional flag; instructs the function to take the element from the floor plan database	all element types
APIFilt_HasAccessRight	additional flag; checks if the element is accessible for the current user	all element types
APIFilt_IsVisibleByRenovation	additional flag; checks if the element is visible by the renovation filter passed in the renovationFilterGuid parameter, default by the current renovation filter.	all element types
APIFilt_IsOverriddenByRenovation	additional flag; checks if the attributes of the element are overridden by current renovation filter	all element types
APIFilt_IsInStructureDisplay	additional flag; checks if the element is visible taking into account the current structure display setting	all element types
APIFilt_IsVisibleByDesignOption	additional flag; checks if the element is visible by the current Design Options settings	all element types

If the value of filterBits is 0, only the existence of the element is checked. This routine helps you quickly test different attributes without converting the whole model, for example when you walk through all the elements, and test for the existence of the 3D representation of an element.

Example

GS::Array<API_Guid> elemList;
ACAPI_Element_GetElemList (API_LineID, &elemList);
DBPrintf ("number of lines = %ld,", elemList.GetSize ());
 
short visible = 0;
short onStory = 0;
short inView = 0;
for (GS::Array<API_Guid>::ConstIterator it = elemList.Enumerate (); it != nullptr; ++it) {
    if (ACAPI_Element_Filter (*it, APIFilt_OnVisLayer))
        ++visible;
    if (ACAPI_Element_Filter (*it, APIFilt_OnActFloor))
        ++onStory;
    if (ACAPI_Element_Filter (*it, APIFilt_InCroppedView))
        ++inView;
}
DBPrintf ("%d visible, %d on the view\'s floor, %d in the cropped view\n", visible, onStory, inView);

ACAPI_Element_Get()

GSErrCode ACAPI_Element_Get	(	API_Element *	element,
		UInt32	mask = 0 )

Returns information on the main parameters of a given element.

Parameters

element	[in/out] The element participating in the operation.
mask	[in] Optional mask. Currently valid values are 0 and APIElemMask_FloorPlan. In the latter case, the elements in the floor plan database are counted directly, without changing the database first.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed parameter is nullptr; element
• APIERR_BADID - The element reference is invalid (guid). The element type is invalid, or the element type is not supported by the server application
• APIERR_DELETED - The element does not exist in the database

Remarks

This function returns information on the main parameters of a given element in the API_Element structure, which is a union of the different element structures. There is only one way (from API 18 or later) to identify the element:

• pass the guid of the element in the element header. The information returned is the main data of the element; further information can be obtained with the ACAPI_Element_GetMemo function, where applicable; the hasMemo field of the header indicates the existence of the extra information. Please use filtering with the ACAPI_Element_Filter function before calling this function; in this case you can spare the conversion time in certain cases. Please note that the attributes referenced by the element may be invalid. The layer attribute is the only one, which must exist. Other type of attributes my be deleted without editing the element database, it results that elements may refer missing attributes. In this case the ACAPI_Attribute_Get function returns an error code.

Example

GSErrCode           lastErr;
API_Element         element;
GS::Array<API_Guid> columnList;
 
lastErr = ACAPI_Element_GetElemList (API_ColumnID, &columnList, APIFilt_OnVisLayer | APIFilt_OnActFloor);

ACAPI_Element_GetCompoundInfoString()

GSErrCode ACAPI_Element_GetCompoundInfoString	(	const API_Guid *	elementGuid,
		GS::UniString *	infoString )

Returns the compound info string of the given element.

Parameters

elementGuid	[in] the Guid of the element
infoString	[out] the composite info string of the element

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - any of the parameters is nullptr
• APIERR_BADID - no element found by the specified Guid
• APIERR_BADELEMENTTYPE - element has no info string

Remarks

For hotlinked elements the info string is composed of the element's own info string and the hotlink element's info strings it placed via.

ACAPI_Element_GetDefaults()

GSErrCode ACAPI_Element_GetDefaults	(	API_Element *	element,
		API_ElementMemo *	memo )

Retrieves the actual default settings for the element of type.

Parameters

element	[in/out] The desired element for which the defaults are needed.
memo	[out] This is needed only in case of library part-based elements (including zone stamps).

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed parameter is nullptr ; element
• APIERR_BADID - The element type is invalid, or the element type is not supported by the server application
• APIERR_REFUSEDCMD - The element type is not a valid target for the operation; API_SectElemID

Remarks

This function is used to obtain the actual default settings for an element. The requested type is identified by the type field of the header. The function fills the central part of the API_Element structure with values from the Settings dialog. You have to fill in the geometric information yourself; if you need it. The memo parameter is used only for library part based elements (including zone stamps), where the params field is filled with the actual parameter values of the referenced Library Part. Do not forget to call the ACAPI_DisposeElemMemoHdls function to dispose of the obtained handles. To change the default settings use the ACAPI_Element_ChangeDefaults function. You can use the returned values to initialize the element attributes and parameters to create a new instance. Refer to the ACAPI_Element_Create function for more details. In order to get the default settings of markered element types (API_WindowType, API_DoorType, API_CutPlaneType, API_ChangeMarkerType, API_DetailType and API_WorksheetType) use the ACAPI_Element_GetDefaultsExt function instead.

Example

API_Element     element {};
API_ElementMemo memo {};
GSErrCode       err;
 
element.header.type = API_ObjectID;
element.header.type.variationID = APIVarId_WallEnd;

element	[in/out] The desired element for which the defaults are needed. The element->header.type can be API_WindowID, API_DoorID, API_CutPlaneID, API_ElevationID, API_InteriorElevationID, API_ChangeMarkerID, API_DetailID, API_WorksheetID, API_CurtainWallID, API_CurtainWallPanelID, API_CurtainWallFrameID, API_CurtainWallJunctionID, API_CurtainWallAccessoryID, API_StairID or API_ExternalElemID.
memo	[out] This is needed only in case of library part-based elements (including zone stamps).
nSubElems	[out] The subelem of the desired element for which the defaults are needed.
subElems	[out] The subelem(s) (normal, story handle, interior elevation common marker) of the desired element.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed element parameter is nullptr.
• APIERR_BADID - The element type should be API_WindowID, API_DoorID, API_CutPlaneID, API_ElevationID, API_InteriorElevationID, API_ChangeMarkerID, API_DetailID, API_WorksheetID, API_CurtainWallID, API_CurtainWallFrameID, API_CurtainWallPanelID, API_CurtainWallJunctionID, API_CurtainWallAccessoryID, API_StairID or API_ExternalElemID.

Remarks

This function is used to obtain the actual default settings for a Window, Door, Section, Elevation, Interior Elevation, ChangeMarker, Detail or Worksheet element, as an alternative of ACAPI_Element_GetDefaults. The requested type is identified by the type field of the header. The function fills the central part of the API_Element structure with values from the Settings dialog. You have to fill in the geometric information yourself, if you need it. The memo parameter is used only for library part based elements (including zone stamps), where the params field is filled with the actual parameter values of the referenced Library Part. Do not forget to call the ACAPI_DisposeElemMemoHdls function to dispose of the obtained handles. To change the default settings use the ACAPI_Element_ChangeDefaultsExt function. You can use the returned values to initialize the element attributes and parameters to create a new instance. Refer to the ACAPI_Element_CreateExt function for more details.

Example

API_Element     element {};
API_ElementMemo memo {};

        API_Neig    neig;
        API_Coord3D coord;
        hotspotArray[ind].Get (neig, coord);
        element.hotspot.pen = ind;
        element.hotspot.pos.x = coord.x;
        element.hotspot.pos.y = coord.y;
        ACAPI_Element_Create (&element, nullptr);

GSErrCode ACAPI_Element_GetTextLineLength	(	API_TextLinePars *	textLinePars,
		double *	length )

Returns the length of a line of text in mms.

Parameters

textLinePars	[in] parameters of the text to be measured
length	[out] the length of the text

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - one or both of the parameters are nullptr

Remarks

The index field of textLinePars determines the behavior of the function.

index	Behavior
-1	No line terminator; this is the last line of the text.
0	Line terminators are in the text; measure the whole string in textLinePars->lineStr.
> 0	Length of the line with the specified index.

The textLinePars->drvScaleCorr field determines whether any drawing scale correction is applied.

ACAPI_Element_GetTextSizeFactor()

GSErrCode ACAPI_Element_GetTextSizeFactor	(	short *	api_fontID,
		double *	textSizeFactor )

Returns the ratio of the font capital size and typography size.

Parameters

api_fontID	[in] Font attribute index.
textSizeFactor	[out] The ratio of the font capital size and typography size.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - Any of the parameters are nullptr.

Remarks

Archicad uses the capital font size. This function is used to determine the ratio of the font capital size and typographical size.

ACAPI_Element_GetUserData()

GSErrCode ACAPI_Element_GetUserData	(	API_Elem_Head *	elemHead,
		API_ElementUserData *	userData,
		UInt32	mask = 0 )

Obtains the user data attached to an element or an element default.

Parameters

elemHead	[in] Identifies the element or element default (only fields type and guid are used).
userData	[in/out] Pointer to the user data.
mask	[in] Optional mask. Currently valid values are 0 and APIElemMask_FloorPlan. In the latter case, the elements in the floor plan database are counted directly, without changing the database first.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - The passed parameter is nullptr; userData
• APIERR_BADID - The elemHead is incorrect.
• APIERR_NOUSERDATA - No user data attached with the gived signature

Remarks

This function is used to get the user attached data from an element or from an element default. To obtain data from element default only elemHead->type is necessary and elemHead->guid should be APINULLGuid. To obtain data from an element only elemHead->guid is necessary and it should be set to element's guid. Use the ACAPI_Element_SetUserData functions to push data into the element record. You can read more about this topic at the Save data into Element records paper.
