Titel
Modeling shape and semantics through an intermediate model
Abstract
The idea that many important design tasks and industrial applications could be performed with the help of CAD systms has led to the development of several geometric modeling techniques. Recently, much attention is given to feature-based modeling which aims to capture the semantics of the parts together with the geometric information. The features of a part, which can be generally defined as form elements with some functional meaning, have been identified in the engineering community as the key elements which both provide a convenient language for modeling product parts using geometric and functional information and allow each application to have its own view of the product. In this paper we study the problem to extend a traditional CAD system to a feature-based modeling system through the definition of an Intermediate Model, here presented. The Intermediate Model is based on previous works on Selective Geometric Complex and is able to represent features of non-homogeneous dimensions be sides parameters and geometric constraints. The main advantage of the proposed model is to simultaneously handle different views of the same object by keeping them consistent.
