摘要
The paper discusses proposed solutions for constraint-based modelling, with special emphasis on constructive approaches. A new constructive scheme is proposed that is based on a nonevaluated, constructive solid model. The model definition language is presented and discussed, with the general architecture of the system and the structure of the internal model representation. The proposed approach supports the instantiation of predefined models, parametric geometric operations in 1D, 2D and 3D, variable topologies, and operations with structural constraints.
