Coming from Sketchup and being a Software Engineer, parametric design in FreeCAD is a game changer for me.

For example being able to define a cabinet side length as the outdoor dimension minus twice the side panel thickness allows you to decide wood thicknesses after finishing the design without redoing everything.

However, FreeCAD seems to be highly unstable on macOS and Retina screens are not supported very well.

You’re correct that parametric is cool & FreeCAD adds that flexibility.

One note about Sketchup is it encourages choosing standard sized items from the parts library. Choosing from the library (for example, choosing a standard 2x4 board or a standard door) means you’ll find real-world equivalents at Home Depot & avoid a lot of cost.
