Function Documentation

ACAPI_CurtainWall_GetCWAbsoluteBottom()

GSErrCode __ACENV_CALL ACAPI_CurtainWall_GetCWAbsoluteBottom	(	const API_Guid *	guid,
		double *	bottom
	)

Retrieves the the base height of a curtain wall or its subelem.

Parameters

guid	[in] Curtain Wall or its subelem reference.
bottom	[out] Bottom of the element. This value is relative to the element's home story.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - guid or bottom parameter is nullptr.
• APIERR_BADID - guid is invalid.

Remarks

This function is used to obtain the bottom of the curtain wall or its subelem (panel, fram, junction or accessory). As against the function name the bottom is relative to the element's home story.

ACAPI_CurtainWall_GetCWHeight()

GSErrCode __ACENV_CALL ACAPI_CurtainWall_GetCWHeight	(	const API_Guid *	guid,
		double *	height
	)

Retrieves the height of a curtain wall element.

Parameters

guid	[in] Curtain Wall reference.
height	[out] Height of the curtain wall.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - guid or height parameter is nullptr or the guid is invalid.

Remarks

This function is used to obtain the height - maximal difference of z coords - of the curtain wall.

ACAPI_CurtainWall_GetCWSubElemParams()

GSErrCode __ACENV_CALL ACAPI_CurtainWall_GetCWSubElemParams	(	const API_Guid *	guid,
		API_AddParType ***	params
	)

Returns the calculated additional parameters of a curtain wall subelem.

Parameters

guid	[in] Curtain Wall subelem reference.
params	[out] Additional parameters of library part-based curtain wall subelem.

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - guid or params parameter is nullptr or the guid is invalid.
• APIERR_BADID - The given element os not library part-based.

Remarks

This function is used to obtain the additional parameters of a library part-based curtain wall subelem (panel, frame, junction, accessory). Don't forget to call ACAPI_DisposeElemMemoHdls to dispose the params handle when you're done. This function is a non-undoable data structure modifier function. See more details on this topic at Command Overview.

ACAPI_CurtainWall_IsCWPanelDegenerate()

GSErrCode __ACENV_CALL ACAPI_CurtainWall_IsCWPanelDegenerate	(	const API_Guid *	guid,
		bool *	isDegenerate
	)

Checks whether the curtain wall panel is degenerate.

Parameters

guid	[in] Curtain wall panel reference.
isDegenerate	[out] Is the panel degenerate?

Returns

• NoError - The function has completed with success.
• APIERR_BADPARS - guid or height parameter is nullptr.
• APIERR_BADID - guid is invalid or is not a curtain wall panel reference.

Remarks

Curtain Wall element may contain degenerate panel elements (eg. its length is Eps). These elements are not selectable but for technical reasons database must contains them. This function is used to filter these CW panels.

ACAPI_FreeCWContourPtr()

GSErrCode __ACENV_CALL ACAPI_FreeCWContourPtr

(

API_CWContourData **

contours

)

Frees the curtain wall contour pointer.

Parameters

contours

[in] A pointer to an array of API_CWContourData.

Returns

Remarks

This is the recommended way of disposing the curtain wall contour for compatibility reasons.
