I feed closed PolyCurve to this node and it makes floor ok. Then, I try modifying using SlabShapeEditor, and always one point doesn’t work and remains at 0 level. If I edit the floor sketch it reveals that the floor creation node adds a Span Direction Edge when making floors, and this messes up the slab shape. Two questions:

1. does someone have a better, python floor node that doesn’t have this problem? And
2. can we delete Span Direction Edge from the floor sketch with Python?

Thanks for your feedback Luke, we will look into the slab shape point behavior, could you supply an example definition? I guess it would make sense if we’d expose some more features like the span direction and/or slope.

Interestingly, it seems that I have resolved the issue by using more predictable geometry. In other words, the Revit node does create a span direction, but this does not stop the ShapeEditor from working.

My next step will be to build a floor node that is not bound to dynamo element, so I can use List.Map without losing previous elements.
