This script exports the selected mesh to xfig (www.xfig.org) file format (i.e.: .fig)
The starting point of this script was Anthony D'Agostino's raw triangle format export.
(some code is still here and there, cut'n pasted from his script)
Usage:<br>
Select the mesh to be exported and run this script from "File->Export" menu.
The toggle button 'export 3 files' enables the generation of 4 files: one global
and three with the three different views of the object.
This script is licensed under the GPL license. (c) Dino Ghilardi, 2005
