Curtain Wall > Ceilings?

Just wondering if anyone has been using the new Curtain Wall tool for celings? Using the Place by Shape option, a horizontal CW plane can be generated.

The Ceiling tool has been around for a long time... targeted at relatively simple requirements and written well before BIM object libraries were so readily available.

It would be great to leverage the excellent work already done with the Curtain Wall tool... a quick test on rotating CWs in 3d throws up a few problems.
