What is MIME type "model/step"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
MIME Type: model/step
This type is used for 3D model files that follow the ISO 10303-21 standard. It defines how detailed product data is structured for engineering and manufacturing. The format supports precise geometric and topological information.
- Used for exchanging complex 3D design data between different CAD systems.
- Ensures consistent interpretation of product models across software applications.
- Facilitates collaboration in industries like automotive, aerospace, and industrial design.
- Enables seamless integration of design revisions and product specifications.
Common file extensions include STEP, STP, and P21. Although named differently, they all contain the same type of STEP data.
This MIME type is essential for industries that rely on accurate and interoperable 3D model exchanges.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type
on the command line. Many programming languages also provide libraries to detect MIME types.
Why are multiple MIME types listed for one extension?
Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
