#IDEAS Software??
Yes, we support both ASCII and binary STL files. STL files are triangles only,
no surface or sub-object information. The faces are oriented properly for nice
one-sided (not double-sided) rendering in 3DS. Extremely complex? Well, it
depends on the original geometry. 3DS has its limits: 65,536 faces per object.
If you tesselate an object very tightly, it might result in an STL file with
more triangles than 3DS can handle.
We hope to release InterChange for Windows in a few weeks. If you'd like to see
a sample conversion, feel free to send it to me on disk in the mail, or in
private e-mail, and I'll send it back to you.
