It seems like it has lots of capability but still "punch your monitor" levels of difficulty just trying to do the most basic stuff.
MangoJelly has done an amazing job in churning out high quality tutorials for FreeCAD: https://www.youtube.com/watch?v=t_yh_S31R9g&list=PLWuyJLVUNt...
(this is just one playlist, there's a lot more on his channel).
Also second the MangoJelly tutorials. You will have a much better time if you walk through a few lessons first as opposed to just winging it and expecting to understand how everything works immediately.
Deltahedra is a great YouTube channel for getting the basics.
And it presents nonsensical problems, like offering to create a sketch on the face of an object and then complaining that the sketch doesn't belong to any object. So you have to manually drag it under the object in the treeview. So gallingly DUMB.
Despite all that, I will wrestle with its ineptitude before giving Autodesk a penny. I get stuff done with it and respect those who give their time to develop it.
> complaining that the sketch doesn't belong to any object
The sketch is by default attached to the "active body". Active Body is a simple, but important concept to understand. Any operation you do, including adding a sketch, is applied to what is designated as the active body. You designate the active body by right-clicking on the desired body in the object pane.
> It suffers from too many "workbenches"
Another understandably common source of confusion. There's the ever-confusing Part and Part Design workbenches.
I think it's best to just ignore Part and use Part Design whenever possible. Part lets you do operations at a more granular level, but Part Design provides a lot more QOL enhancements and is more intuitive. For the vast majority of things, Part Design is more than capable. I would only use Part workbench when absolutely necessary.
You probably understand all of this already. It's directed more towards the reader. I feel the need to defend FC when certain accusations are brought up. It's immensely powerful, capable, and usable. In my case, I can work very rapidly with it - though it's taken some time to arrive here. The project deserves more than just aspersions.
The combo of tracing a bitmap (from a scanned drawing) with Inkscape and then saving the result as SVG to bring into FreeCAD has been a frequent workflow for me. It generally works very well.
To clarify about the "active body" though: This problem occurs even when there's only one active body and the shape upon which you've supposedly draw the sketch is part of it. So why is FC complaining?
I'm sure I could grind harder and learn more and make FreeCAD work, but I'm not sure why I'd bother.
I mostly design functional 3D prints. I've found FreeCAD 1.0 fixed most of the annoyances I ran into and I'm pretty productive with it. But, I didn't come into it with an expectation of a SolidWorks or Fusion clone. I learned the tool with its own idioms and it seems pretty straightforward to me. It's not perfect by any means and I've run into the occasional bug. To that end, I've found reporting bugs with reproducible steps goes a long way to getting things fixed.
I'm not sure what it is about CAD in particular, but I find everyone wants the "Blender of the CAD world" while skipping over the decade of investment it took to get Blender where it is. For a long time, discussions about Blender were dominated by complaints about the UX. If we didn't have folks willing to work past a hit to productivity in order to make an investment into Blender, we wouldn't have the amazing open source tool we have today. FreeCAD has all the expectations of a high quality open source CAD tool with hardly any of the investment. Just getting people on /r/freecad to file issues is surprisingly challenging.
By all means, if you're happy with Fusion and don't mind the licensing, have at it. I'm sure there's functionality in there without an equivalent in FreeCAD. I'd personally rather not have my designs locked up in Fusion and see FreeCAD as the best option for me, even if it suffers from the challenges of open source UI design.
