I draw a lot of short lines to surround a complex area, then I want to pull it up into a solid, but find that I can’t select it. I think this may be because some of the lines were drawn in the wrong direction - by which I mean that most of the lines were drawn so that from the beginning to the end of a short line, it went in a clockwise direction around the area, but not all did - some were the other way around. Is it possible to get SU to recognise the area without having to redraw it correctly?
Another example is this : I draw a circle, then attach to it the cross-section of a V-pulley. I select the circle, click the Follow-me tool and double-click the cross-section to make a 3d pulley - and it works fine, but I then find that I can’t select the circle, because it has turned into the sides of a many-sided polygon. Can I recombine them into a circle so that I can select the plane subtended by the circle, and extrude it?
