Changed... me = NMesh.GetRaw(ob.data.name) To me = NMesh.GetRaw(ob.getData(name_only=1)) The line above converts the entire mesh to a python thick wrapper just to get its name, then only to that that same mesh again?? A lot of older scripts did this but theres no reason to do it. in most (all?) cases.. me = ob.data - should be ok, but theres a subtle difference and I dont want to break anything. xfig_export, xsi_export and videoscape_export need error checking too.

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.
