This script exports meshes to DEC Object File Format.
The DEC (Digital Equipment Corporation) OFF format is very old and
almost identical to Wavefront's OBJ. I wrote this so I could get my huge
meshes into Moonlight Atelier. (DXF can also be used but the file size
is five times larger than OFF!) Blender/Moonlight users might find this
script to be very useful.
Usage:<br>
Select meshes to be exported and run this script from "File->Export" menu.
Notes:<br>
Only exports a single selected mesh.
