In order to optimally exploit the large amounts of engineering information stored in contemporary PLM systems, the concept of knowledge based engineering (KBE) can be considered from a PLM perspective. By eventually combining product structures and implicit semantics provided by PLM-systems on the one hand, and domain-specific standards on the other hand we believe to have identified a key enabler KBE. As an initial step we describe a coupling of a CAD system with a semantic representation of engineering knowledge using formal ontologies. By application of automatic reasoning, engineering knowledge gained from the product structure and domain-specific standards allows us to reduce time-consuming manual work in classifying overlaps between parts in a CAD model as intentional overlaps (e.g. with gaskets) or design failures.
