> what makes you prefer SolveSpace to FreeCAD or programmatic cad like CadQuery?
I prefer GUI apps over CLI/scripting.
SolveSpace is my main 2D/3D CAD since SolveSpace 2.0 became[0] FLOSS. (previously used KOMPAS-3D, but it is proprietary)
Now I'm QA (tester) & i18n (localization) contributor to the SolveSpace development for 6 years now, so you may ask me anything about it.
Itself I'm a teacher of design and technology, with a bachelor degree in technical drawing & CGI + master degree in PM, so really like to take part in FLOSS development as UI/UX QA & PM, see my profile on GitHub[1]
In last 20 years for curious reasons also I use OpenSCAD QCAD/LibreCAD, FreeCAD and a lot of other FLOSS CAx & GIS apps from-time-to-time (mostly for testing & bug reporting).
> What do you use it for?
For all CAD-related works (see my #DailySolveSpace[1] resources): solid 3D modeling & producing 2D drawings, simple CAE analyzing, etc.
JFTR, I'm moderator of /r/SolveSpace sub on Reddit too.
