Ah, I thought as much. I assumed it must be FreeCAD as it's the most feature rich one. These days whenever I need CAD I usually turn to SolveSpace which is also parametric but significantly lighter and straight to the point. For sure it lacks some of the useful features FreeCAD has but I rarely need those. Another one I reach out for is OpenSCAD, being a software developer this one clicks very well with me.
