I wrote this script because I wanted a linear polygonal bridge between two objects, with the editable taper and twist funtionality. The linear option of the default Maya Bridge command doesn't allow access to the taper curve while the smooth and smooth plus curve option doesn't provide a straight bridge path. This script solves the problem by bridging between two faces using the polyBridge command's curve function. It then rebuilds the curve as a one span linear curve. This creates a straight bridge section beween the two polygonal faces but also allows the user to access the bridge profile feature of the node. The user interface allows you to adjust the curvy-ness of the bridge curve before applying.
-Select two polygonal faces on the same object. Combine two polygonal objects. The objects can be open, but the polygons cannot be on a border edge.
-Type source ekBridgeUI.mel;ekBridgeUI; into the commandline and press enter.
CurvyPath controls how much curve the bridge will have, 1 is the same as standard smooth plus curve option in the bridge, 0 is linear with a curve, and -1 reverses the curve. (Try 2 and -2 for wacky results)
Divisions controls the number of divisions in the script.
-Press Bridge Polys.
-Delete history on object and delete curve(s) when done.
Please note: This script was written for 8.5 on OS X. It works on OS X 2008 and while it should work, please be advised that I have not tested it on any other platform. As always, use at your own risk.
