What is a step file?

A STEP (Standard for the Exchange of Product model data) file is a standardized file format used for 3D computer-aided design (CAD) models. STEP files are used for exchanging CAD data between various software programs and systems, making them a popular file format for collaboration and interoperability in the manufacturing industry.

STEP files can contain geometric information, such as shapes and dimensions, as well as metadata like materials, textures, and assembly structures. They can also store specific design details, such as tolerances, annotations, and product information.

STEP files are commonly used in industries like aerospace, automotive, and manufacturing where accurate and precise 3D modeling is necessary. They are supported by most CAD software programs and can be easily converted to other file formats for compatibility with different systems.
