An Automated Approach for the Discovery of Interoperability
This addresses interoperability issues for CAD system users, but appears incremental as it builds on existing methods for shape property analysis.
The paper tackles the problem of testing interoperability between CAD systems by developing an automated approach that discovers interoperability issues based on approximately-invariant shape properties of CAD models, showing that standard format exchanges do not guarantee shape preservation. They implemented a program called DTest for this testing.
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.
