3d Cad Design Libraries With Free Download

WARNING: FreeCAD has moved!

FreeCAD code and release files are now hosted on github at https://github.com/FreeCAD/FreeCAD

Only older files and code are available 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.

Features

Rock-solid OpenCasCade-based geometry kernel, allowing complex 3D operations on complex shape types, and supports natively concepts like brep, nurbs, booleans operations or fillets
Full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python
Complete access from python built-in interpreter, macros or external scripts to almost any part of FreeCAD, being geometry creation and transformation, the 2D or 3D representation of that geometry (scenegraph) or even the FreeCAD interface

Thank you very much for the program! Thank you for distributing it under a free open source license!
I'm using version 0.19. Get it from github.com/FreeCAD/FreeCAD. I've found freecad to be as powerful as the costy packages out there, and it's open source. You can compile it (I have) and you can add in plugins as well. I gave it a 4 out of 5 for ease because it's too powerful to be easy, although the tutorials on youtube really go far in smoothing the learning curve. I've designed very complex gear systems after only a couple of days of playing. I now design things, export to stl files, and then 3d printed them. Such freedom!
Excellent program for the design of buildings and structures. Thanks to the author of the project!
