NIST has released updated versions of the Creo models with GD&T (geometric and dimensional tolerancing) information. The models are part of a test system to measure conformance of CAD software to ASME standards for PMI. The test system includes test cases defining part geometries with PMI concepts applied to them, test models that are implementations of the test cases in CAD software, and model verification and validation based on comparisons between test models implementing the save test case.
For more information and to download the free CAD models, go to http://go.usa.gov/mGVm
