Hi John,
When you use the "Smart edge display" do you see something wrong in your model ?
In this display mode:
- dotted edges are sharing two faces, and are soft edges.
- straight edges are sharing two faces, but are sharp for extraction and lightning
- bold straight edges belongs only to one face
If you see bold edges where you meant they should share 2 faces, delete the involved faces and recreate them.
Send your project to support@realviz.com so we can isolate the problem.
Thanks,
Stef
