A prototype sketch-based architecture modeling system with traditional design habits

Widely used for architectural design, CAD systems such as AutoCAD, 3ds MAX, provide powerful modeling functionality. However, they are often too complex for an architect to use, especially during the conceptualization stage involving primarily sketching of design ideas. Also, interactions with conventional CAD systems are typically driven by mouse and keyboard, but these devices cannot be used as freely as a pencil. For an architect, a tabletPC with stylus provides an ideal interface for design sketches. In this report, we study sketch-based architectural design and modeling and develop a prototype system which respects simplicity and traditional conceptual design habits. Our system provides a seamlessly integrated design/draw environment with intuitive and focused interaction built in, both in an attempt to provide a design environment that closely conforms to the architects' conceptual design habits.
