Video tutorial (Part 2) showing how you can use some of the different editable polygon commands to change the underlying structure of an object.
You can attach different objects together and use the "Bridge" command to then join selected polygons from each object to form a set of new polygons between the selection.
"Hinge From Edge" creates new polygons based on the edge that has been selected and the angle chosen in the caddy.
"Extrude Along Spline" uses a separate spline object as the basis for extruding out from a selected polygon.
