Representation and system-agnostic automated CAD interoperability testing based on model interchangeability

In this paper, we present theoretically-supported frameworks to test CAD system interoperability based on shape comparison criteria. We introduce a command line tool that provides indirect, representation-independent comparisons of CAD models via abstract proxies and query-based interpretations. Our frameworks support local comparisons using differential properties and offer a broad range of global comparisons. We allow testing for generic CAD software designed for different operating systems or scripting languages. Users can specify tolerance values for testing, ensuring accuracy. This approach bridges CAD model representations, enabling effective interoperability evaluation across diverse systems without requiring in-depth knowledge of CAD software or representations.
