||Recent advances in computer graphics and 3D user interfaces have enabled the emergence
of 3D sketch modeling as a viable approach to architectural design, especially in the early
schematic phase. This paper describes how a system can be built and used which integrates
the capabilities of a good structural analysis system in the user-friendly working
environment of a design-oriented modeling program.
The structure of a building model as seen by finite element algorithms is a schematic
idealization of the building's physical structure into nodes, elements, internal releases,
boundary conditions, and loads. The more familiar architectural model used for design
visualization represents spatial elements such as roofs, floors, walls, and windows.
Rather than treat these models independently, the structural model can be defined in
relation to the architectural as a virtual model with inherited common characteristics and
additional relational and attribute information, using feature-based geometry data
structures to organize topological intelligence in the spatial model. This provides the basis
for synchronous modification of structural and architectural aspects of the design.
