What non-FOSS software have you been unable to quit?
For me, Google video search, Google books (Internet Archive is good, but doesn't always have the same stuff), Adobe InDesign (but in the process of learning LaTeX), and Typewise. As for the Google stuff, I liked Whoogle a lot, but almost all their instances seem to have been blocked or shut down. Also, apologies if this is repeating an earlier post.
Solidworks - A reliable FOSS 3D CAD package would be amazing... Parametric Blender?
Photoshop/Illustrator - I know how to do 50% of what I need to in GIMP/Inkscape, but I lean on Adobe usually!
I used to use Solidworks and NX some. I think there are similarities. That is sketch based. I admit though, not really learned FreeCAD either. On my list some day.
There is also ondsel, which is basically freecad with some polish maybe. It looks the same to me. But one day when they solve the topology renaming thing and when they have an interface that's not openly hostile I'd love to try it
I would agree that FreeCAD is the best, but it's not slick and doesn't feel particularly robust. Don't get me wrong, I have no rose tinted glasses on when it comes to Solidworks, but it's generally very usable and very powerful.
I worked with Creo for years, and ProE before that. I still have nightmares about the cascading unresolved reference screens. I've never used NX, but my understanding is it is AAA, though not super user friendly by default. I've pretty much exclusively used Solidworks for over a decade now, and I have to say that it's generally pretty well behaved, and I've never really found I couldn't do what I wanted to in it. Thus it has become my crutch.
Solvespace is a FLOSS light weight 3D CAD alternative. Although it lacks the advanced features of Solidworks works really great for most of my 3d designs.
