![]() ![]() 3D model of the assembly generated by the STEP File Analyzer and Viewer.Download the SolidWorks and Siemens NX models.The parts and assembly were modeled in Dassault Systemes SolidWorks and Siemens NX 1953. 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 test cases are intended to be valid presentations of GD&T defined in the ASME Y14 tolerancing standards, some of which may not be commonly used. Simpler GD&T strategies could have been used. The FTC and CTC are not intended to represent best practice in how to apply GD&T (geometric dimensioning and tolerancing) to a part.
