Feature Request: API access to the cutting/section plane definition of an export solid

[WickiDominik]

Hi all,

I'm building a custom IFC section generator and need to read out the cutting/section plane definition of an export solid (Ausgabeelement) via the API.

I already found functions to work with export solids, e.g.:

• attribute_controller.is_export_solid(element_id)
• element_controller.get_export_solid_content_elements(element_id)
• element_controller.set_export_solid_contents(export_solid_id, element_id_list)
• shop_drawing_controller.assign_export_solid(ceo_element_id_list, element_id_list)
• cadwork.element_type.is_export_solid / set_export_solid

However, none of these expose the actual cutting/section plane (cut name + normal vector + distance from global origin, or a reference point) that defines the export solid's section geometry.

Use case:
My IFC section generator needs to automatically produce the corresponding section views per part. For this I need the geometric plane definition of each export solid directly from the Cadwork model, instead of reconstructing it manually.

Proposal:
A function along the lines of

get_export_solid_cutting_plane(element_id: ElementId) -> plane_3d  # or normal_vector + distance

get_export_solid_cutt_name(element_id: ElementId) -> name [str]

that returns the plane used to define a given export solid.

If there's already an (undocumented) way to get this, I'd appreciate a pointer as well.

Thanks!
