Those FTC test cases were remodeled to be smaller, have simpler PMI, include fasteners to join the parts, and to be more easily manufactured. The models are based on FTC-07 (box), FTC-08 (lid), and FTC-09 (plate) from above. This dataset is based on the project Design, Manufacturing, and Inspection Data for a Box Assembly. Some of the PMI defined in a test case might not have been modeled in a CAD system as semantic and/or graphical PMI. Inventor 2018, Inventor 2019, Inventor 2021ĬAD models indicated by * above were verified as part of the testing project and documented in the Test Results below.

The FTC and CTC are not intended to represent best practice in how to apply GD&T (geometric dimensioning and tolerancing) to a part. Representative STEP AP242 and AP203 files for each test case, many with graphical and semantic PMIįor an explanation of FTC and CTC, follow the link to the left for the MBE PMI Validation and Conformance Testing Project.Browse the PMI annotations in the test cases. These files can be used to create your own CAD models of the test cases. The definition files contain PDFs of each test case drawing, STEP AP203 files of only the test case geometry, and an explanation of the GD&T.
There are three types of files to download:
