There doesn’t seem to be any source for Vex building instructions on the web, so I went ahead and created the HobbyVex CAD project. The HobbyVex CAD project is based completely on the FREE tools from the LDRAW.org package.
The instructions to get started are now available at http://hobbyvex/CAD/index.htm. Give it a try. Publish those building instructions!! The first bundle of parts (most of the starter kit) is now available along with a preliminary version of the first robot model and instructions on [http://hobbyvex/Robots/index.htm.
Given that people are intermingling Vex and Lego, using the LDRAW tools has a singular advantage that all the Lego parts are already defined. The tools in the LDRAW.org package include a simple way to produce rough building instruction images and also a more complex way to produce professional quality building instructions.
I hope the Vex community will be interested in producing building instructions for the many robots already out there. I’m willing to help where I can; right now I’m working on getting the rest of the parts library converted over.](http://hobbyvex/Robots/index.htm.)
