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!
FreeCAD is the best FOSS program I know for solid modeling. Librecad works for 2D.
Man, I tried to learn FreeCAD, but coming from the Inventor/Solidworks paradigm it was hard.
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.
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.
Actually Solidworks is consider low to mid market. NX and whatever PTC calls their high end now are the main stream CAD systems as far as I know.
