When I sweep it in Rhino the result is an equally tidy polysurface.
When I sweep it in GH the result is a gnarly single surface.
Should I take this to mean that if I want a clean polysurface I needs to explode the path, and orient the section curve on each segment, sweep them individually, then join?
Or is there a component eluding me that will do this.
Crease splitting options aren’t exposed in out-of-the-box Grasshopper components, so, yes, you will have to run the operation on the individual segments.
