This is a bug that we know about, the cut surfaces are treated as an outer surface and projected with cover fills. I can’t say anything about the schedule when will it be corrected, please contact support for information.
There is a rather complicated workaround:
– each piece of the model that has the same building material can be projected using parameters to model only that part, fills overridden with the attributes from a “Building_Material_info” request.
– the visible and overhead parts have to be projected in a separate call, they show correctly only with a full model.
For an example see “CWFrameRegDouble” macro.

Thank you so much for your answer, Péter!
Somehow a “relief” to know it’s a bug.
But good grief! I think I’d rather wait for the bugfix then 😀 (I’m using the complex profiles, so I don’t know what’s actually displayed with the object, which makes the workaround undoable).
Hopefully it doesn’t take too long to fix. Will it be retrofitted into AC 24 (which still got this issue) and 23?
