What is MIME type "model/vnd.3dm"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

model/vnd.3dm is a MIME type for 3D model files. It indicates that the file holds data for 3D objects and design elements.

This type is often used in professional design and computer-aided design software. The files using this MIME type store detailed geometric data such as curves and surfaces. They may contain annotations and metadata for accurate modeling.

The format is mainly seen with files like 3DM, which belong to a family of 3D model files.

Main use case: Storing 3D designs for architecture, product design, and engineering.
Technical detail: It serves as a container for complex geometric data that CAD and 3D modeling software can interpret.
Interoperability: Helps exchange detailed 3D models between different applications and platforms.

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.
