Openings in IFC

[Franz Sdoutz]

Why is WYSIWYG still NOT a thing?

I want to show ALL Elements “to be demolished” in IFC.

I want to evaluate that demolition quantity (easily and not via complicated schedule filterings that need to include NEW openings but only in existing elements  …)

[Franz Sdoutz]

No one?

Assuming the Problem lies with IFC standard definition (IfcOpening cannot be a solid)

the following workarounds are futile:

Also, Openings can NOT be reclassified as “solid elements” (-> ifcBuildingElementProxy) and Archicad elements can NOT be classified as IfcOpenings.

Openings can also NOT participate in Boolean operations.

One way to program this would be to automatically creat/accesse internal "intersection solids" (Boolean operation) and switch those on export for openings.

Call this model filter export setting: “All 3D Elements with openings as solids”

OR just NOT use openings AT ALL. (laborious, but feasible)
