True, this is the other way. I always forget that we have this option now.
Well, I think the issue will persist as long Archicad doesn't incorporate the FPCP correctly for CWs. See, what I was seeing (nothing) was totally "correct"! Just because Archicad will always look from above for the projection! I mean, that's kinda obvious somehow, if you think about it. In Archicad terms a projection is always something you'll do from above.
The floor plan display option has "Projection" and "Projection with Overhead" – but the latter only means "please project the element even if above the FPCP" (a simple projection would not show up at all). It doesn't mean it would actually generate a RCP-like floor plan projection! And I think THAT is the main problem.
It will get solved. I hope you are as patient as I am. 😌
