Rhinocommon tip on trimming breps to pipes

pipe = Rhino.Geometry.Brep.CreatePipe(crv, off, True, Rhino.Geometry.PipeCapMode(0), True, tol, atol)
Rhino.Geometry.Brep.Flip(pipe[0])

You can flip closed polysurface (solid) pipes inside out and trim your breps.
McNeel, please don’t “fix” this. :joy:

Hi @Asterisk,

I’m sorry, but I don’t understand. Is there a question here?

No, no question, just a tip that a solid’s normal can be oriented inwards as long as it’s not a real object. Which is helpful when I want to trim breps on the inside of a solid.
