I have a series of complex polysurfaces (including and similar to the one attached) which I am trying to unroll so that I can extract a set of 2D curves that plan out each surface, unrolled and in sequence as if the whole polysurface was gradually unrolled surface by surface. I’ve tried unrolling and UVcrvs but can’t seem to get anywhere - can anybody help?
@theoutside Why do you recommend Smash or Squish instead of UnrollSrf or UnrollSrfUV? My experience is for developable surfaces UnrollSrf and UnrollSrfUV are generally more accurate than Smash or Squish.
ExrtrudeCrv will refuse to make a bad object if the input curve has vertical segments. It is possible to Loft between two curves with vertical segments and create a bad object.
The original file contains a single polyline. I assume the polysurface was created with Gumball Extrude, which in contrast to the ExtrudeCrv command extrudes the curves no matter what.
Thanks very much, this is great. When you say repair the degenerate surfaces, did you literally just re-draw them or is it something else you did to fix them?
