Hi

I want to create the ceiling using Dynamo like Floor.ByOutlineTypeAndLevel for typical flat ceiling ( basic & compound for different material type)  
I don’t think we have that feature yet in Dynamo 1.0.

We need Roof.ByOutlineTypeAndLevel also as the basic generation from Dynamo to Revit even though the clockwork has Roof.SlabShapeByPoints.

Roofs should be possible with the “NewFootPrintRoof” method. There’s an existing topic on that:
