CHS UCB My Agenda within BID u Teaching Applicable Design Skills u Developing Better CHS UCB My Agenda within BID u Teaching Applicable Design Skills u Developing Better CAD Tools & Methods. Tight coupling: Research Instruction

CHS UCB BID Issues u Different fields of design have the same key issues, CHS UCB BID Issues u Different fields of design have the same key issues, but different nomenclatures. Goals: Unify the language; Create a catalog of issues, a list of potential solutions.

CHS UCB Doing Design u In my courses on graphics and on geometrical design, CHS UCB Doing Design u In my courses on graphics and on geometrical design, I found that students often acquire a decent overview of various CAD tools & design techniques – but only at a textbook level. u When asked to design a plastic spoon, they are completely stumped or come up with totally impractical design plans. My goal is to remedy this situation.

CHS UCB (my) “BID Manifesto” The proof of any new methods lies in their CHS UCB (my) “BID Manifesto” The proof of any new methods lies in their application to relevant design problems. u Apply u Have new theories & methods of design. the students actually design things – which then (hopefully) prove to be demonstratively better than earlier design.
