kokopelli is an open-source tool for computer-aided design and manufacturing (CAD/CAM).
It uses Python as a hardware description language for solid models. A set of core libraries define common shapes and transforms, but users are free to extend their designs with their own definitions.
The CAM tools enable path planning for two, three, and five-axis machines. At the moment, paths can be exported to Universal and Epilog laser cutters, the Roland Modela mini-mill, three and five-axis Shopbot machines, and plain G-code. A modular workflow system makes adding new machines easy.
In addition, models can be saved as .svg and water-tight .stl files.
kokopelli has been tested on Mac OS 10.6+ and Ubuntu 12.04 LTS.
A Mac application is available here.

kokopelli grew out of the MIT course "How to Make Something that Makes (Almost) Anything".
In that course, I worked on fast geometry solvers and developed a fairly basic UI. My work expanded on the fab modules project, which allows fab lab users to make physical artifacts on a variety of machines.
This work grew into my Master's thesis at the MIT Center for Bits and Atoms. This thesis focused on volumetric CAD/CAM workflows. Now that it is complete, I'm releasing this tool for others to use and develop. It has already been used by folks in How to Make (Almost) Anything and Fab Academy, but I'm excited to offer it to a larger community.
