I would love for you to explain how the workflow is any different than in something like SolidWorks? I use SolidWorks in my day job and I use FreeCAD exclusively for my personal projects. It was a pretty seamless transition for me. Sketch->Feature, repeat, paying attention to order of operations in your model tree. What’s so different?
Is FreeCAD’s UI a little rough in places? Perhaps, but a lot of the things that people complain about in FreeCAD are present in commercial software. If there’s one thing that SolidWorks might do better is allowing you to get away with things like over-defining geometry accidentally. It’s more forgiving of lazy modeling.
FreeCAD has improved significantly in just the last few years. There is a good community around it. We need more people using it and learning how to model.
I also have this question. What is so different about the workflow between FreeCAD and other 3D CAD software? If you can do one, you can do the others.
