- 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
