Spin polygonal edges

You can spin edges on a polygon mesh using the Spin Edge Forward or Spin Edge Backward option. Spinning an edge modifies your polygonal mesh by changing the selected edges’ connectivity 1 vertex at a time. You can use this to quickly change the flow of topology of your mesh. An example of this is shown below.

You can spin an edge forward or backward based on its winding direction. If you spin an edge that was spun before, or spin an edge multiple times, Maya edits the offset attribute of the existing history node rather than creating a new one.

Spinning an edge does not affect the vertex IDs or edge IDs, however as you spin an edge, the adjacent faces rotate along with it.

Note: You can only spin edges that are attached to two faces. You can spin multiple edges at once, but only 1 edge per face.

To spin an edge or edges

1. Select the edge(s) you want to spin.
2. Select Edit Mesh > Spin Edge Forward or Edit Mesh > Spin Edge Backward. Alternatively, you can also press Ctrl + Alt + Right Arrow or Left Arrow to spin the edge forward or backward respectively.

   The edges spin in the appropriate direction based on their individual winding orders.
