Hi mnemonicimage, that is the right demo version that does have saving enabled.

But yes - only surface data can be exported to a mesh file format.

If your model consists only of curve objects (like lines for example), then that won't export to a mesh file format.

If you'd like, you can send your model file to me at moi@moi3d.com and I can take a look to see what the problem is.

I don't really know of a good location to download iges files... But to do a basic test you could do something like draw a sphere or box using the "Draw solid" tools in MoI. You should be able to export solids like that to a mesh file.
