What is an STP file?

An STP file is a 3D assembly file supported by various mechanical design programs such as TurboCAD and Fusion 360. It contains three-dimensional object data saved in the Standard for the Exchange of Product Data (STEP) format. STP files are saved in a text-based ASCII format that conforms to the STEP Application Protocols ISO 10303-2xx.

More Information

STP files are primarily used for transferring 3D graphics between different CAD and CAM systems. Many manufacturers use the STP file for designing and pricing molds or manufactured parts.

NOTE: STP files may also use the less common .STEP extension.
