Dave has always incorporated the use of free-hand sketching in the design  and presentation development process.  It has been shown that the most creative approach to design is through the brain/hand connection.  Computers have become the means for developing the drawings needed to build a project, but the direct link of the brain and hand still prove to provide the quickest means for developing design ideas that can be understood by clients..  These sketches for a design competition proved to be the winning ideas that got the architect the project.
