WireCut adds complexity to geometry

I’ve noticed in V9 that WireCut tends to add complexity to my geometry (and in V8, too).
I like to keep my geometry as simple as possible, of course, but running WireCut operation often divides otherwise simple surfaces and solids into multiple arbitrarily joined surfaces.

I’ve taken to using this workaround:

  • Copy geometry to WireCut
  • Open an instance of Rhino 7
  • Paste geometry into V7
  • Perform WireCut operation in V7
  • Copy geometry back into V9 (or V8)

It’s a bit of a chore, of course, but it gets the job done and I can move forward in V9 with geometry that is still simple like I built it.

Surely this is not how WireCut is intended to work in future? Hope you guys can fix this!

Best, Christian

Would make sense to add an example and a screenshot showing the issue…

Confidential client work, so can’t share.
But I can try to replicate with some generic geometry, if this isn’t a common issue.
Just need to meet my deadlines first…

Are you cutting with a polyline with many segments?

If so, try rebuilding the curve first

Yes, please. Wirecut simply creates an extrusion in the cut direction, then mutually splits the extrusion and the object to be cut and rejoins the parts, discarding unneeded stuff if necessary. It should not complexify anything, if it does, it may be a bug that needs fixing.
