Connect
Modify > Connect
 

Description:

      The Connect (Modify > Connect) command is a quick way of splitting faces and adding extra edges. In vertex mode, if two or more vertices in a face are selected when the call to Connect is made, the face will be cut by edges connecting those selected vertices.  In edge mode, if two or more edges of a face are selected, each of those edges will be split in half by a new vertex and the face will be split by edges connecting the new midpoint vertices.  If more than two edges of a polygon are selected, this will have the effect of insetting a new polygon into the first.


Notes:

- This command is often used in conjunction with Select Ring (Selection > Select Ring) in order to quickly subdivide a ring of edges..
