Introduction
If you want to contribute CAD Designs to OSE, then join this team! OSE is always looking for help in developing the GVCS and ultimately in creating a collaborative network of people to draw upon for all open source projects. Whether you're a seasoned engineer or brand new to CAD this is a great place to learn, share and create in an open, collaborative environment with people from around the world.
Head on over to the CAD Team for more information.
How to Join
You can start by posting a short text about yourself and your skills on the Introductions category of the discussion forum.
Then, please read the Team Culturing page and fill out the survey, as described there. Don't forget to add [[Category: CAD team]] to your survey page so that you get listed.
Standardized Building Materials
In order to facilitate modular designs and make it easier for growing communities to bootstrap their development, we should try to develop a minimal list of "building blocks" out of which to build larger machines. Although different mechanical systems require differently sized components, we don't need continuous variation in every property. By limiting the number pieces we use in the machines we gain several advantages: sourcing parts is easier, buying more of fewer parts will likely get us better prices on parts, communities require fewer tools to be fully bootstrapped if there are fewer parts that need manufacturing processes. In addition to these benefits it would be nice for the project as a whole to have a good list of what everything costs to allow for easy cost calculations of different design choices.
