Hi Baz, thanks for the link! I'll have to d/l it and play with it a bit. I like Arbaro and have had some success with it. It does tend to make some poly-heavy models, but
they hold up real well next to the camera like a "hero tree" should. I've found that .dxf format is the way to go as far as export for this app. The object file format tends to make the app hang, especially with complex models.
You may have to manually add ".dxf" or ".obj" when you name your file.
