Example parts

Ten real parts, from a motor plate to a watch movement bridge.

Each example is a part an engineer would actually order: named, toleranced, drawn to ISO and sized to the standard parts it mates with — a NEMA 17 motor, SMA jacks, a microscope slide, M3 screws. Open any render or drawing full size, turn the part in 3D, download the drawing and the STEP model.

How they are proven: each part's program is written with Studio's own CAM and run to the end in the twin with the closed-loop drive model, and the finished workpiece is compared with the design part cell by cell; each card shows the run time, the comparison with the design and any alarms. More example parts come with updates after 1.0.

Eleven more parts are designed and drawn, from a lens mount to a centrifugal impeller. Each comes with a Studio update, and onto this page, once its program has run to the end in the twin and the result matches its design.
