Surface folding

[Aerojedi (Jeff)]

I built a curve from 22 control points. I did a 2d scale and made length shorter and moved it up the y-axis of the ref plane. If I build a surface between the two curves (EdgeCurves) I get a good surface.

If I move the upper curve back on the x axis (same y location) and build a surface I get a surface the folds on itself. It appears the control points on the upper have reversed from the lower curve. Same curve and control points only moved out x axis 5.5 inches. I’ve tried to find a way to reverse the order of the control points but no luck. Any suggestions? Using 8.0 windows.

If you can send a file that would help a lot understanding the problem and helping you forward.

looks like history may be biting you?

try historypurge then try your transform.

I found my issue. I created a line between the first control point between each curve and the last control point of each curve to bound my surface. then used “Edge Curves” and the surface works.
