My usual FreeCAD workflow involves drawing constraints-based 2D shapes in Sketcher, then extruding/revolving them. There are some numbers typed in, but those are mainly just key dimensions.
One of FreeCAD's bigger faults IMHO is that the right/best way to do things isn't easily discoverable (as seems to be common in CAD), and the documentation (like many OSS projects) is a bit hit-and-miss...
For example (I've only skimmed this video, there are likely better ones), check out https://www.youtube.com/watch?v=rgstQi9jpGc
Now I find the sketching pretty intuitive, albeit a bit clunky and slow. The number one feature I'm missing is the program telling me WHAT degrees of freedom are still unconstrained in a sketch.
Following the tutorials is a lesson in futility. The UI is clunky and small mistakes can have catastrophic outcomes for new users. Undo works in mysterious ways.
When I found myself stuck on a tutorial, a google search rewarded me with the phrase "pary designer workflow has changed substantially in 0.17." I followed a second tutorial on the wiki. Whatever eas changed - it's worse. I considered installing an older version.
Instead, I dropped FreeCAD, installed OpenSCAD, and had my part drawn in a couple hours.
