3D Interoperability

Healing and Preserving 3D Model Intent

Part and parcel with model-based engineering is model translation. Because the model is now the specification, accurate translation from one system to another becomes essential. But even if a model is accurately read, the intent of the model has to also be properly interpreted. Key to proper model interpretation is healing — the process of modifying model data so that it conforms to the rules of the target system, while adhering to the intent of the source.

One-Way Associativity for 3D CAD Analysis Applications

Analysis applications often use solid models generated by CAD systems as their input; for example, the structural analysis of an engineering model. The user of the system applies a set of loads and boundary conditions to the model, and then the software performs its analysis and supplies a set of deformations or stresses in the material, allowing an engineer to look at the results and decide whether the design fits its purpose.

Desperately Seeking System Tests

In one of my former lives as QA manager, one of the problems that continually grated on my nerves was the mysterious nature of our nightly regression test failures. Our test suite was incredibly fragile, such that in analyzing failures during our convergence period to determine whether they were truly indicative of a potential customer problem or just whiny tests, I was constantly faced with making decisions based on vague error information emitted from black box tests of unknown origin. A lot of manual analysis was required for every release.
