Add property to components (parts of a composite wall or slab)

Hello everyone,

 

Is it possible to add a property to a non-element object like a components (parts of a composite wall or slab) ?

 

I've found this method which allow to add a property to element : ACAPI_Property_AddProperty (API_PropertyDefinition& definition, const GS::Array<API_Guid>& elemGuids)

 

When i check which object is an element, components are not : https://graphisoft.github.io/archicad-api-devkit/union_a_p_i___element.html

 

My goal is to try to add property to the component itself so when I export an IFC, each IfcBuildingElementPart has it's own parameter value which can be different for each layer.

 

For what I know, only 3 things can be obtained about components:

  1. The ID (API_ComponentID) not a GUID, it's the number in the compound structure.
  2. The 3D geometry (API_Component3D) but I've never tried.
  3. The quantity (API_CompositeQuantity).

But I hope I'm wrong and that we can do more things, like manipulate properties.

 

Thanks
