Free Solidworks models with PMI developed by NIST

Discussion created by Robert Lipman on Dec 30, 2014

NIST has released updated versions of the Solidworks 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 same test case.
