There is another way you can do it with ACIS if your 3D design is in
solids ( R13). You can export the file via .SAT (ACISOUT) to
TriSpectives Professional ( TriPro has a clean .STL out
capability including tesselation control. TriPro runs $399.95 on sale.

When ouputting .STL from any of the AutoCAD Revisions, even on a setting
10, the files still can suffer poor tessellation. A couple of ways to
overcome this:

1) Increase the part size by a certain factor (2x, for example), then do
STL output. Once the .STL is output you can reduce the part back to
   percentage. This basically fools the output into more triangles. I've
never tried,
   but hear this works.

2) Output an .IGES file and use Brockware or other translators to output
   file. On AutoCad, CADkey and some of the other less expensive
   option is preferrable to using their own .STL utilities.

Best of Luck,
