    FreeCAD

    FreeCAD

    a parametric 3D CAD modeler

    This is an official mirror of FreeCAD. Code and release files are primarily hosted on https://github.com/FreeCAD/FreeCAD and mirrored here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

    CompassCAD

    CompassCAD

    very good CAD software

    CompassCAD is a simple, light, yet minimalist 2D-only CAD software. It lowers the barriers for novice CAD users to learn about CAD and sketch their very own design from scratch, and ensures everyone can try CAD. If applicable, it could also be used as a professional software with features such as collaboration (up to 2 persons, more will be added later on), SVG exporting, ready to be printed and shared with your co-workers. CompassCAD has a very small project size bundled in a single file, so your file is ready for distribution without breaking any of your favorite messaging app's file limit.

    Pyfab

    Python library for fab/lab control

    Allows one to program fablab (factory and/or laboratory) in the same way as we program computer. Imagine commands like: "dim screw12 as new screw" or "mold(form_piston_081212, brass)" or ''gear(3)=lasercut(steel2,"biggear.gc")". This approach will let us program highly automated and self-deploying or even self-replicating factories. I am more engineer than programmer and just beginner in python. So it looks like community help will be needed :)
