In the attached file I have a profile of a window I am trying to create in a surface. The “frame” is the projection of a planar window shape on the surface.
My thought was to create the window opening by using the shape to create a surface, extrude the surface, then subtract the extrusion (offsetsrf).Problem Windows.3dm (3.0 MB)
The problem that when i try to use edgesrf or notworksrf then offsetsrf, I get a weird shape (note surfaces at the side)
It does work if I use Patch but patch is very slow.
I am not wondering if I am approaching this in the wrong way and, if so, how to go about doing this.
