Machined test part NIST CTC-01 (STEP)
A realistic machined part from NIST's PMI CAD test models (Combined Test Case 1), designed to exercise geometric dimensioning and tolerancing in CAD software. STEP AP203 solid geometry: open it in the viewer to rotate, measure and section it, or use it as a reference part for CAD, CAM and inspection workflows. The matching dimensioned drawing is in the Drawing Library.
