In the last version of IFC manager I added an option(a bit experimental) to export extrusions for super simple geometry like a straight beam or floor slab. It does not work when there are cutouts.
Than you do get the best type of solids in IFC.
For example: Classify wall frame as an IfcElementAssembly, the beams as IfcBeam/IfcColumn or IfcMember, and inside the beam an object classified as IfcExtrudedAreaSolid.
@brewsky Curious, though. Theoratically, you could define the profile itself as an IfcRectangleProfileDef and the path as the IfcExtrudedAreaSolid?
It doesn’t seem to simplify though…
It kind of looks the way ProfileBuilder is handling it.
Do you have an example:)

The current functionality works a bit simpler, just make sure you place extruded geometry in a component classified as IfcExtrudedAreaSolid and set the z axis to the extrusion direction (from the top of my mind, I’m not behind a PC)
There are a few in the sample SketchUp model at SketchUp-IFC-Manager/sample at main · BIM-Tools/SketchUp-IFC-Manager · GitHub
The roof beams for example.
