Most inventors keep more than written records about their work. Many draw to capture their nonverbal thought processes and to explore ideas and consider options. Inventors may sketch their initial ideas and, once their concept is better defined, make scale drawings by hand or with CAD. Drawings are often found on napkins, in notebooks, or on computer files. Drafting materials, art supplies, and computer programs attest to an inventor’s skills and preferred materials.
