I just started learning FreeCAD version 0.21 and finding it tough slugging. And no wonder, I supposed. FreeCAD folks and the Ondsel polls have acknowledged that UI is a weakness. But thanks to the excellent MangoJelly tutorials [0] on YouTube, I feel like things are finally starting to soak in. And in watching those tutorials, I've come to realize just how powerful FreeCAD is. The 0.22 release will be a big step up and I'm looking forward to it.
I'm hopeful that with the renewed focus in the project that it becomes the next Blender or the next KiCAD: an open source tool that can hold its own against current commercial offerings. Go FreeCAD Go!
