Which MIME types are related to file extension ".gdl"?
The .gdl file extension is associated with 1 MIME types:
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .gdl Files
GDL files are files that hold three-dimensional model data.
They use the MIME type model/vnd.gdl. This indicates they contain vendor‐specific 3D structure elements.
- 3D Modeling: They store geometric data used to render or visualize objects.
- CAD Applications: They can be used in computer-aided design and architectural software.
- Rendering: They may include surface and texture details useful in graphics engines.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .gdl file?
A .gdl file typically contains a script written in Geometric Description Language. It is primarily used by Graphisoft ArchiCAD to define parametric 3D objects, doors, windows, and other architectural building elements through code.
How can I open a .gdl file?
The most reliable way to open and visualize these files is using Graphisoft ArchiCAD. Since the file contains code that generates geometry, you need the specific GDL interpreter found within ArchiCAD to render the 3D model correctly.
Can I edit a .gdl file with a text editor?
Yes, because GDL is a text-based scripting language similar to BASIC, you can view and edit the source code using simple editors like Notepad or TextEdit. However, you will not see the resulting 3D shape without loading the script into a compatible CAD program.
How do I convert a .gdl file to other formats like DWG or OBJ?
You generally cannot convert the script file directly. Instead, you must open the file in ArchiCAD, generate the 3D view of the object, and then use the Save As or Export function to save the geometry as a DWG, DXF, or OBJ file.
What is the MIME type for GDL files?
The standard MIME type associated with these files is model/vnd.gdl. For more information on model-related media types, you can visit mime-type.com.
Why won't my standard 3D viewer open a .gdl file?
Most standard 3D viewers expect static mesh data (like polygons), whereas a .gdl file contains parametric instructions to build the model. Without the specific GDL engine to interpret these instructions, a generic viewer cannot display the object.
General 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 can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
