I’ve got these curves and whenever I try sweep 2 rail or network srf I always get creases. I’ve tried exploding it and match surfacing it but that usually makes things worse.
The crease happens where the two outer curves meet at a point. So I tried smoothing that out with a blend surface but then I can’t even make a sweep or network surface
Chan someone explain why this crease happens?
