Current inventory

30,000 part drawing pairs are available. Each pair contains a mechanical part model in STEP format and its technical drawing in DWG format.

Sample

The sample contains 25 pairs selected from the component parts in the Mechanical Assembly sample. They are ordered by STEP face count, from highest to lowest. The selected parts have 14 to 603 faces.

Each pair has its own folder with model.step, drawing.dwg, drawing.pdf, and render.jpg. manifest.json records the face count, file size, and SHA-256 checksum for each file. Model dimensions use millimetres.
