An Automated Approach for the Discovery of Interoperability
share
In this article, we present an automated approach that would test for and discover the interoperability of CAD systems based on the approximately-invariant shape properties of their models. We further show that exchanging models in standard format does not guarantee the preservation of shape properties. Our analysis is based on utilizing queries in deriving the shape properties and constructing the proxy models of the given CAD models [1]. We generate template files to accommodate the information necessary for the property computations and proxy model constructions, and implement an interoperability discovery program called DTest to execute the interoperability testing. We posit that our method could be extended to interoperability testing on CAD-to-CAE and/or CAD-to-CAM interactions by modifying the set of property checks and providing the additional requirements that may emerge in CAE or CAM applications.
