I prefer to use free and open source options when I can, but when it comes to CAD I use the free but proprietary Onshape. I’ve previously tried but didn’t enjoy FreeCAD, but now we have Ondsel, an improved version that fixes problems and addresses community requests.

In this video, I compare Ondsel to FreeCAD, Onshape and even Fusion360 (this is the most I’ve ever used it). Trying to separate frustrations from being unfamiliar, I make a list of what works well, what is limited, and what still needs to be improved.

I really despise pointing out flaws in something free and open source, but I’ve tried to do so constructively, providing specific examples where these limitations are a problem. I’m sure some FreeCAd advocates will be upset over my conclusion, but the way it and Ondsel approach 3D modelling is quite different from Onshape/Fusion360/Inventor/Solidworks/SolidEdge/etc. They have converged on an intuitive and logical approach. FreeCAD/Ondsel deviates from this, but is it an improvement or hindrance?

Thanks to my patrons Derek and Novaplusplus for their assistance in making this video.
