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.
