Does ProgeCAD export to any other file formats other than DXF, such as IGES?

I tried the PolyTrans evaluation, and I don't think it will work for you, it is more built to read polygon mesh data out of a DXF file and not to translate curves and lines.

I know that Rhino will work to translate this - you can download a demo version that will save 25 times at http://www.rhino3d.com if you want to try it.
