I have this loft that works fine at 3.590", but I need it at 3.600. If I try to extend the plane that the second sketch is on the additional .010, I get the self intersecting error. The top & bottom sketch's are the same but it twists at 90. I would think shorter would be harder for the twist. I've attached the file.
Thanks in advance for any input.
