Re: pic: DryErase is the new CAD...
As JVN likes to say, design is an iterative process. Whatever technique helps you iterate will improve your design.
We like to re-cover a very large (4 ft. x 16 ft.) workbench with heavy brown paper, taped down in the corners. The paper stays there from kickoff until ship day. It is used to sketch ideas full-scale, often by tracing actual parts.
I have sometimes witnessed sketches from the big bench cover being cut out with scissors to make templates for aluminum parts. We have also used cardboard and plywood to make templates and prototypes.
Dry erase is good for quick sketches, calculations, and what-if discussions. CAD is the best way to make sure complex things are going to fit before you cut them.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
