Overview

Current CAD/CAE interfaces force the user to know precise dimensioning and data from the start, restricting and inhibiting idea flow. Most design-support systems are more aptly called drafting systems because they force the user to sacrifice design creativity for structured input. These interfaces limit the production of better first-time designs that would reduce the product development cycle.

The goal of the MECDE project was to derive effective conceptual-design aids. Specifically, this effort investigated the role of shape in the concept development stage of the design process. The MECDE project adopted the innovative approach of developing cognitive models. For example, one model represented shape conceptualization and was used to analyze how a product definer thinks about shape information. A second model illustrated the process of shape manipulation that is required for developing an automated system in support of conceptual design activities.
