Description
The Spin Edge command allows you to change the way an edge divides two faces, by rotating the edge. A single edge which is connected to precisely two faces must be selected in order for this command to work. The edge will in effect be rotated by using a different pair of the faces' vertices for its endpoints.
Notes
- It may be necessary to perform this operation multiple times in a row to achieve the desired edge placement.
