Scheme for automatic dimensioning of CSG defined parts (Q1110248)

A general scheme for automatic dimensioning of objects defined by solid modelling techniques is presented. The first part of the paper describes a theory that relates the geometrical definition of a solid and the dimensions that appeared on the engineering drawings. The second part demonstrates a method that automatically generates adequate dimensions from boundary representations of the solid models. Implementation of the scheme on a constructive solid geometry modeller, PADL2 of the University of Rochester, is also described.
