FreeCAD is the only Free and Open Source CAD/CAM program on the market. It is a very capable CAD program but the most important aspect of it, is the freedom. It allows you full control over your creations without an expensive license. If you plan to use your designs commercially, SolidWorks and Fusion 360 expect you to hand over some cash.
It is under active development and is getting better every week. You can try out new features by downloading the weekly development builds on GitHub. If you like FreeCAD, and it has been useful to you, please consider supporting the project by committing to a small monthly donation. If you can’t afford to do that, share your FreeCAD projects on social media to spread the word and show others what FreeCAD is capable of!
