Interpcrvon (multiple) surfaces?

Hello, I’m trying to make an interpolated curve between the two points that you can see on the picture. The problem is that when I start the interpcrvonsrf command it divides the surface (which was extruded together from only one curve) into multiple surfaces so I can’t draw the curve between those two points. How do I fix this? (drape is not an option)

Hello - there are a couple of ways out of this - if you set UseExtrusions to make ‘polysurfaces’ (or surfaces) and not extrusion objects, then you can set ExtrudeCrv > SplitAtTangents=No - if the input curves are tangent, then a single surface will result. Another solution is to make a temproary version of the curve to extrude which has been rebuilt.
