In my FlowAlongSrf workflow, I use CreateUV or Unroll to set up my base shape. For Flow, I measure the length and then create a crv of the same length on the CPlanes. Am I missing a command to ‘unroll’ a curve into a straight line?
Well, if you want to create a line along the X axis the same length as your curve, you could use something like this:
import rhinoscriptsyntax as rs def UnrollCrv(): crv=rs.GetObject("Select curve to unroll",4,True) if not curve: return rs.AddLine([0,0,0],[rs.CurveLength(crv),0,0])
