I’m trying to create a floor opening using the Create Shaft component shared here: Rhino.Inside®.Revit
Feeding it a closed polyline curve, like a simple rectangle, i keep recieving an error saying “grasshopper Lines must be in closed loops” I’ve tried again and again with different polylines, genereated in different ways but with no luck.
I’ve then tried with a simple circle as the input curve. In this case the component works perfectly, generating an opening in the desired floors in Revit.
Anyways i’m missing something? Anyone can help?
