CAD application: (third party sortware)
- solidworks is used to create/edit models. Save in binary format, high triangulation of models would result in smooth curves.
- Google SketchUp (last tested with version 8) is freely available and works well for our purposes. It does not output STL files, but the plugin skp_to_dxf.rb will allow for export to ASCII STL file (via the Tools menu in SketchUp). Make sure to clean up the geometry before export, and don't export guide lines. The exported STL file must be converted to binary format for use in Objet Studio. Use the attached stl_ascii2bin.py script to convert it.

- OpenSCAD http://openscad.org yet another open source CAD program. Uses a different "programmatic" approach for defining the parts instead of a visual one. Can output ASCII STL files, use above converter.
- Ashlar Vellum Argon http://www.ashlar.com/sections/products/argon/argon.html a professional 3D CAD software, offers a monthly rental model ($40/month, minimum two months).
- Free-CAD http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page, cross platform, open-source CAD software. Can be scripted using Python. Seems to be missing a way to indicate resolution of round objects in STL export.
