Parametric CAD is judged by what survives a design change. SolveSpace is a lightweight constraint-based CAD tool; test it with a part that resembles your work rather than a perfect tutorial rectangle.
Sketch a bracket with holes, dimensions, and a relation between features. Change one dimension and check whether the model remains valid. Create a simple assembly or drawing if your workflow requires it, then export to the format used by your fabricator. Review SolveSpace's documentation for supported operations and export formats.
Compare alternatives on constraint clarity, error recovery, performance, and whether a teammate can edit the design without rebuilding it. Verify units, tolerances, and exported geometry in a second viewer. If you need advanced surface or collaboration tools, state that explicitly; a small CAD tool can be excellent within a well-defined scope.
