What is a .step file?

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 this file

Use an example STEP file to test CAD B-rep parsing, precise-geometry import, and interoperability tooling between mechanical design and CAM applications.
