It's not a perfect analogy, and Blender does have some parts which resemble the sort of data structures you'd use in a CAD modeler. I think with enough plugins and customizations, you _could_ twist blender into something that resembles a CAD modeler, but it's really an uphill fight compared to selecting tools which were designed with that goal in mind from the start.
