Let’s say I create an uncapped pipe around a line. This results in a surface that is closed in U-direction and open in V-direction. The naked edges only run around the two pipe ends.
How can I “open” the U-direction, that is, also have naked edges along the seam? I have tried the UnjoinEdges command but that does not work.
If I split it elsewhere along a V-isocurve (i.e. in the same direction as the desired open seam), I end up with two pieces. I want one piece that is open in U- and V-direction.
