Rendering and Profiler use a Parasolid function called Spun-outline Profile. This function doesn't work properly on every part. We are working with the authors of the Parasolid kernel to improve this functionality and will continue to update GibbsCAM as they come available.

Known side effects of Spun-Outline failures are:
  • The system is crashing when the user triggers CPR or Profiler.
  • It takes forever to start CPR or Profiler.
  • The shape provided by Profiler is wrong.

  • To bypass these failures we introduced the "Use Spun Outline for Lathe Profile" switch located in File-->Preferences-->Machining dialog. You can disable this option by unchecking it.
