step
What is a .step file?
model/step
STEP (Standard for the Exchange of Product model data) is an ISO 10303 CAD format that stores precise boundary-representation solid geometry and product data as structured text. Unlike mesh formats, it preserves exact curves and surfaces for engineering use. It is the leading neutral format for mechanical CAD interchange.
How to use a .step file
Use an example STEP file to test CAD B-rep parsing, precise-geometry import, and interoperability tooling between mechanical design and CAM applications.

- STEP — AP214 Cube Corner PointsA minimal, well-formed STEP AP214 file holding the eight corner points of a 10 mm cube. For testing STEP header and entity parsing and CAD-exchange tooling.
- Spur Gear — 16 teeth (STEP)The same 16-tooth spur-gear profile as STEP AP214 CARTESIAN_POINT entities — the CAD-exchange twin of the DXF, for testing STEP parsing.
