| summary |
Presented is a method for explicitly representing dimensions, tolerances, and geometric features in solid models. The method combines CSG and boundary representations in a graph structure called an object graph. Dimensions are represented by a relative position operator. The method can automatically translate changes in dimensional values into corresponding changes in geometry and topology. The representation provides an important foundation for higher level application programs to automate the redesign of assemblies and to automate tolerance analysis and synthesis. A prototype interactive polyhedral modeler based on this representation was implemented |
