Connecting edges creates new edges between adjacent pairs of selected edges. The Connect Edges dialog settings let you specify the number of new edges, the amount of separation from each other, and their general location.
Tip: Connecting edges, and in particular the Slide function, work best with ring selections.

Segments—The number of new edges between each adjacent pair of selected edges. Default=1.
Pinch—The relative spacing between the new, connecting edges. Negative values move the edges closer together; positive values move them farther apart. Default=0.
If Segments=1, the Pinch setting has no effect.
Slide—The relative positioning of the new edges. Default=0.
By default, the new edges are centered. Positive values move them in one direction, while negative values move them in the opposite direction. The new edges cannot move beyond existing edges.
