Thanks for all the useful replies, especially Roger's. Obviously we got through last season without it, but it's reassuring to know that it's not required for good designs.

We use every method that you can think of. Solidworks, DryEraseboards, graph paper, the blank side of my Latin quiz, wildly gesturing hands, an actual prototype (gasp!), an unused napkin during dinners on Thursdays and Fridays during regionals... I agree with Roger and EricH that each have their place.
