This is really a general Rhino problem, but I’ll post it here since I’m using the WIP.
In the attached file I’m trying to blend the seat surfaces to the flat top. As you can see I piped their intersection and trimmed back. I seem to be having the problem with the back round edge of the seat, for some reason it won’t select when I try to chain the edges for BlendSurface. Same with Sweep2. I can make 3 separate sweep surfaces (side, back, side),but they don’t have continuity.
What am I doing wrong?
