• Problem: Offset surface may become self-intersecting. If the curvature radius of a face is smaller than the offset distance, the surface will become corrupt or it will vanish when it is offset.

• Possible Solution:

◦ Use a smaller offset distance that avoids self-intersecting surfaces.

◦ Use the surface analysis command to check which values are the maximum possible.

• Problem: Offset surface loses contact to a neighboring face. This may happen if an adjacent face is tangentially or nearly tangentially connected to the offset face.

• Possible Solution:

◦ Use the Lift command to add new faces.

◦ Offset the neighboring faces with the same value also.
