Database items named elements are global collections of constuction and drawing elements which are placed onto the floorplan, Section/Elevation etc. windows.

API functions operating on the element databases begin with the ACAPI_Element_ prefix, refer to the Element Manager for more details.

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, then the server application parses the request based on the values and passes the return parameters in the same parameter. This is why most of the functions do not have the const directive in the prototypes.

Refer to the Save data into the Element records document to get information how to save/assign custom data to the element records and save it into the project file for later use.

New in API 26 In version 26 the Analytical element types were replaced by the externalElem member. The former structures (e.g. API_AnalyticalLinkType) can be obtained by the appropriate functions (e.g. ACAPI_AnalyticalModel_GetLinkFromElement).



Version: API 2.1 or later
