Converting Dead Geometry to Parametric Building Elements in Dynamo/Revit

[BimAmbit]

for some reason, the file link doesn’t work. but i think you can isolate the bottom edge of the face and use one of these since they only want a curve.

i encountered the null output a while ago, and here’s an explanation from jacob.

Can't select all the faces of a mass

This is because for the node to work the surface has to be tied to a geometry reference of a Revit element. Such references are fairly easy to construct with solids in the Revit API, but I do not see an easy method to do so for meshes… backing into one by playing with the stable representation might be the only way, and that is… alot.
