My preferences go NX -> SolidWorks -> FreeCAD -> Creo
Not sure why people still use Creo but that's all my current company uses. I've been using FreeCAD for personal use over the past 10 years or so and it's better every time I open it. I wish I was a better coder so I could contribute!
I used to use AutoCAD years ago, but I haven’t used a CAD program since then. Are those 4 projects all aiming to fill the same space? And if so, why do you continue using your third favorite?
I use FreeCAD if there's something I want to mess around with off the clock. The other 3 cost exorbitant amounts of money that only businesses can afford. I think student versions might exist for some but it's easier to just have a CAD program free and clear.
