I use Autodesk Inventor when at work, but I’m trying to learn FreeCAD for my own hobby project. And while I’ve had to reprogram some workflows I’m slowly getting there. What really excites me about FreeCAD is the different workbenches, such as CfdOf which gives you a nice and understandable gui for OpenFOAM, finally making CFD somewhat accessible to the masses.
There’s also a lot of new and improved functionality coming out with 0.22.
My favorite feature of FreeCAD is the spreadsheet. F360's Parameters window...it's been awhile since I've used it, but you weren't able to rearrange or sort parameters, there weren't any hotkeys or ways to quickly enter values so you had to move your hand from the keyboard to the mouse a lot, plus it wasn't as multifunctional.
F360 parameter entry was so lacking. And what a strange feature to not fill out since as you say it's basically just a spreadsheet. Hell, let us import actual spreadsheets so I can have a baseline each time for parameters I'm always inputting such as 3d printer specs (line width etc)
