you should see my sketch books from FIRST, i had more pages of gear calculations, BOMs, and math than i did sketches of actual parts. i ended up sketching out my gearboxes with a compass before i even touched solidworks.
HOWEVER.....
using SW to put hard numbers on your designs, and figure out the nitty gritty is much more work than the napkin sketches you use to jot down ideas. to go from sketch to product (especially in real world engineering) takes a lot more professionalism, thoroughness, and precision than a napkin can provide.

BOTH the innovation for a elegant design and the know-how to make it work are required to make ideas reality. Otherwise your just a drafter or a dreamer
