                hlColor.f_red += 0.1;
                if (hlColor.f_red > 1.0)
                    hlColor.f_red = 0.0;
            }
 
            bool wireframe3D = false;
            API_RGBAColor nonHighlightedElemsColor = {0.7, 0.7, 0.7, 0.95};

Parameters

filterAndCutSettings	[in] Parameters of the 'Filter and Cut Elements in 3D' dialog box

    ACAPI_Environment (APIEnv_Change3DImageSetsID, &filterAndCutSettings);
 
    filterAndCutSettings.elemTypeFilter.clear ();
    filterAndCutSettings.elemTypeFilter.insert ({API_WallID, true});

ACAPI_View_Change3DProjectionSets()

Changes the parameters of the 3D projection.

Parameters

proj3DInfo	[in] Parameters of the '3D Projection Settings...' dialog
switchOnlyAxonoOrPersp	[in] Optional parameter. If it is not nullptr and the value is true, only the isPersp field of proj3DInfo is considered

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - proj3DInfo is nullptr
• APIERR_NOPLAN - No open project

Remarks

This function is used to change the 3D projection. If you pass true in the switchOnlyAxoOrPersp parameter, the kind of the projection (parallel or perspective) will be changed only, all the other parameters will be ignored. If the value of camGuid or actCamSet field of API_3DProjectionInfo is non-zero, the perspective projection will be defined according to the camera identified by camGuid. If camGuid is invalid, the first camera of the camera set defined by the actCamSet field will be used. Otherwise the perspective settings will not be related to any floorplan camera element, and will be defined by the API_PerspPars data. These fields are irrelevant when changing the axonometric projection parameters.

Example

/* Change to the next perspective camera */
API_Element           element;
API_3DProjectionInfo  proj3DInfo;
GSErrCode             err;
 
BNZeroMemory (&proj3DInfo, sizeof (API_3DProjectionInfo));
err = ACAPI_Environment (APIEnv_Get3DProjectionSetsID, &proj3DInfo, nullptr, nullptr);
if (err == NoError && proj3DInfo.isPersp && proj3DInfo.camGuid != APINULLGuid) {
    BNZeroMemory (&element, sizeof (API_Element));
    element.header.guid = proj3DInfo.camGuid;
    err = ACAPI_Element_Get (&element);
    if (err == NoError && element.camera.perspCam.nextCam != APINULLGuid) {
        proj3DInfo.camGuid = element.camera.perspCam.nextCam;
        err = ACAPI_Environment (APIEnv_Change3DProjectionSetsID, &proj3DInfo, nullptr, nullptr);
    }
}

ACAPI_View_Change3DStyle()

• APIERR_NOACCESSRIGHT - The user does not have Teamwork privilege to modify 3D styles.

Remarks

Renaming styles is not supported, do not edit the style->name field as it is used for the identification of the existing style.

Example

// Get the name of all styles.
GS::Array<GS::UniString> stylesNames;
GS::UniString currentName;
ACAPI_View_Get3DStyleList (&stylesNames, &currentName);
 
API_3DStyle apiStyle {};

ACAPI_View_Change3DStyle ( &apiStyle);
 
// Create a new style based on the current one, with a different sky color. Finally set it as the current style.
GS::UniString testStyleName ("testStyle");
if (!stylesNames.Contains (testStyleName)) {
    apiStyle.bkgSkyColor = { 0.2, 0.2, 1.0 };
    GS::ucsncpy (apiStyle.name, testStyleName.ToUStr (), API_UniLongNameLen);

		API_Point *	point
	)

Convert a model coordinate to screen in the current database.

Parameters

coord	the coordinate to convert
point	the associated screen coordinate

Returns

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

Remarks

This function is used to determine the pixel of a real coordinate. It is the inverse function of ACAPI_View_PointToCoord function. Note that different coordinates may be assigned to the same pixel. The conversion mainly depends on the window size, on the actual drawing scale and zoom settings (ACAPI_Drawing_GetDrawingScale, ACAPI_View_GetZoom) which means the projection is database dependent.

Example

API_Coord    c;
API_Point    p
GSErrCode    err;
 
c.x = 1.0;
c.y = 2.0;
err = ACAPI_Database (APIDb_CoordToPointID, &c, &p);
err = ACAPI_Database (APIDb_PointToCoordID, &p, &c);

ACAPI_View_Change3DStyle ( &apiStyle);
 
// Create a new style based on the current one, with a different sky color. Finally set it as the current style.
GS::UniString testStyleName ("testStyle");
if (!stylesNames.Contains (testStyleName)) {
    apiStyle.bkgSkyColor = { 0.2, 0.2, 1.0 };

Remarks

This function is used to redraw the content of the current (front) window.

Example

GSErrCode    err;

To change the actual zoom box refer to the ACAPI_View_SetZoom and the ACAPI_View_Zoom functions.

Example

GSErrCode       err;
API_Box         zoomBox;
API_PrintPars   printPars;
short           numOfStepsBack;
 
BNZeroMemory (&zoomBox, sizeof (API_Box));
zoomBox.xMin = -1.5;
zoomBox.yMin =  0.0;
zoomBox.xMax =  1.5;
zoomBox.yMax =  3.0;
err = ACAPI_Automate (APIDo_ZoomID, &zoomBox, nullptr);

To get the actual zoom box refer to the ACAPI_View_GetZoom function. To restore one of the previous zooms use the ACAPI_View_ResetZoom function. You can modify the zoom of the 3D model window with the ACAPI_View_Change3DWindowSets environment function. In order to set the zoom of the top window, use the ACAPI_View_Zoom automation function instead.

Returns

• NoError - The function has completed with success.
• APIERR_BADWINDOW - The command cannot be executed on the topmost window.

ACAPI_View_Zoom()

GSErrCode ACAPI_View_Zoom	(	API_Box *	zoomBox = nullptr,

• APIERR_NOPLAN - There is no open project
• APIERR_BADDATABASE - The active database is not the top window
• APIERR_BADPARS - The passed zoomBox is incorrect (empty box) or zoomRect is too small

Remarks

This function performs a zoom or a fit in window operation on the front window, and rebuilds it. If the zoomBox parameter is passed, the given zoom factor will be set up. Alternatively you can pass a rectangle to define the zoom in pixel coordinates. If both parameters are nullptr, a Fit In Window command will be executed. To set the zoom box of a 2D drawing type window without rebuilding the database, use the ACAPI_View_SetZoom database function. You can retrieve the current zoom box of a 2D drawing type window with ACAPI_View_GetZoom. If the top window is the 3D model window, only the zoomRect parameter is considered. You can retrieve the current window size with the ACAPI_View_Get3DWindowSets environment function. You can also modify the zoom of the 3D model window with the ACAPI_View_Change3DWindowSets environment function.
