Hi everyone,
I’m automating ceiling creation in Revit with the DirecShape command.
After the “fake” ceiling elements are placed, I’d like to align their material pattern with project geometry.
I dug into solid/face/material/grid…etc deconstruction, but didn’t find the proper functionality.
This is what I know so far:
Thanks!
