To Remove from Wireframe
1. Select one or more wireframe pieces of any type.
2. Click Constrain > Wireframe > Remove from Wireframe. Alternatively, right-click in the graphics window and click Remove from Wireframe.
◦ If the selected wireframe is black or green, it is deleted resulting in a one-sided edge pair. Removing green wireframe breaks the topological connection it represents.
◦ If the selected wireframe is blue, the surface split it represents is removed and the UV-curves originally used to create the split are displayed again.
