Parallel Curves

How to create a parallel curve using a law?

When creating a parallel curve with the following characteristics:
  • non linear input curve
  • non planar support
  • radius law which vanishes into a flat shape
may lead to quality defects in the zone such as angular discontinuities as shown:

 

Workarounds
Add a small offset value to the radius law (value higher or equal to 0.001mm) so that it does not get null.
