I agree with this, the process of mechanical design very much involves messing around with things visually. I've interned in a place that still used "good old" 2D, non-parametric autocad, and a lot of the "premilinary" design work took place on scratch pieces of paper. Sketch stuff up quickly, see how it looks and fits together iterate. Move to autocad for a to-scale sketch, then to drafters to the official engineering drawings.
