Fusion is a really cool tool to learn.
replyIt's a flavor of 3D modeling called "constraint-based." You've heard the adage that if you give a million monkeys typewriters, eventually one will write something coherent? Constraint systems embody that same idea: There are infinite possible 3D models. You keep adding constraints until you narrow it down to only one possible solution that fulfills all of them.
I've been learning FreeCAD, while it's still more frustrating than Fusion or SolidWorks it's much better than it used to be pre-1.1, and it's FOSS. Also constraint-based, I've been using the new spreadsheet view as the source of all constraint dimensions, with parts derived by binding to top, front, or right-side orthographic "master" sketches. Much like hand-drawn design, where you draw the orthographic views and use those directly to create an isometric view.
replyI love FreeCAD, designed some parts, did a bunch of Solidworks challenges and entered CAD comps.
replyI also love playing with build123d, dune3d (uses solvespace constraint) and SolveSpace.
Do love Solidworks but I'm on linux now so time to embrace the other options more.
