title	The Strategic Use of CAD: An Empirically Inspired, Theory-Based Course

summary	The inefficient use of complex computer systems has been widely reported. These studies show the persistence of inefficient methods despite many years of experience and formal training. To counteract this phenomenon, we present the design of a new course, called the Strategic Use of CAD. The course aims at teaching students efficient strategies to use a computer-aided drafting system through a two-pronged approach. Learning to See teaches students to recognize opportunities to use efficient strategies by studying the nature of the task, and Learning to Do teaches students to implement the strategies. Results from a pilot experiment show that this approach had a positive effect on the strategic behavior of students who did not exhibit knowledge of efficient strategies before the class, and had no effect on the strategic behavior of those who did. Strategic training can thus assist users in recognizing opportunities to use efficient strategies. We present the ramifications of these results on the design of training and future experiments.

summary	The exploding functionality of current computer-aided engineering (CAE) systems has provided today’s users with a vast, but under-utilized collection of tools and options. For example, MicroStation, a popular CAE system sold by Intergraph, offers more than 1000 commands including 16 ways to construct a line (in different contexts) and 28 ways to manipulate elements using a “fence”. This complex array of functionalities is bewildering and hardly exploited to its full extent even by frequent, experienced users. In a recent site visit to a federal design office, we observed ten architects and three draftsmen using MicroStation.
