Semantic representation of CAD models based on the IGES standard

Abstract

The design process of a product is iterative due to a series of changes that range from client specifications to quality defects. From each of such changes, designers end up with a considerable amount of design files, additionally, if files have to be exchanged with other partners they have to be translated based on the available neutral file formats. In order to identify specific elements stored on the resulting translated files, the designer needs to make use of a CAD system. If the amount of files to consult is significant, the task becomes excessively time consuming. The approach presented here, focuses on the creation of semantic models providing the user; query capabilities over a collection of CAD models in order to identify a specific design based on particular conditions along with exploration capabilities to detect key elements from any IGES CAD file. Both capabilities possible without the need of using a CAD system. © Springer-Verlag 2013.
