I was trying to revolve a curve for a turned newel post. The revolve command gave me a “self intersection curve” warning? I exploded the curve into its 47 segments joined re-joined, etc., till i found the problem. There must be an easier way to find there errors? I looked up and found old test commands that are no longer recognized. Does this mean they are just gone, or turned into actual rhino commands?
IntersectSelf is not perfect but will find these a lot of the time. If your curve has 47 segments, there is a good chance it can be made more simply.
a “hack” is to close the curve then run curve boolean (in this case 2x) … this will clip out all the bad bits and leave you with a curve that should have no self intersections-
now… is this curve awesome? no. should it be rebuilt? very likely yes.
does it have any self intersections?
