I have a 3D curve that I’m trying to extrude. During the axis extrusion, there is collision where the line double backs on itself creating surface.
I’m ultimately trying to mill this piece on a lathe, however this ridge adds material to the true model.
Is there a way to restrict the loft so it does not create a surface in the closed loop portion?
I have attached my .gh and a picture of the physical milling the model to help show the issue.
