Spin Edge
Modify > Spin Edge
Description:
The Spin Edge (Modify
> 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.
