What is MIME type "application/iges"?

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

application/iges is the MIME type for files using the IGES format. IGES stands for Initial Graphics Exchange Specification and is used to share complex geometric and technical drawings.

This format is essential in CAD environments. It lets different software exchange 2D sketches and 3D models while preserving design details.

Primary use case: Data exchange between diverse CAD/CAM systems
Supports: Curves, surfaces, and solid geometry
Industry applications: Automotive, aerospace, and industrial design

Files related to this MIME type are usually saved as IGS or IGES.

Usage Examples

HTTP Header

When serving content with this MIME type, set the Content-Type header:


    Content-Type: application/iges

HTML

In HTML, you can specify the MIME type in various elements:


    <a href="file.dat" type="application/iges">Download file</a>

Server-side (Node.js)

Setting the Content-Type header in Node.js:


    const http = require('http');    
    
    http.createServer((req, res) => {    
      res.setHeader('Content-Type', 'application/iges');    
      res.end('Content here');    
    }).listen(3000);

Associated file extensions

FAQs

What file extensions are associated with application/iges?

The standard file extensions for this MIME type are .igs and .iges. You can learn more about these specific extensions at /file-extension/igs and /file-extension/iges.

How do I configure Apache to serve IGES files correctly?

To ensure your Apache server sends the correct headers, add the AddType directive to your .htaccess file or main configuration. Use the line: AddType application/iges .iges .igs.

Can web browsers display application/iges files natively?

No, most modern web browsers (Chrome, Firefox, Edge) cannot render IGES 3D geometry natively. When a user clicks a link to this file type, the browser will typically download the file so it can be opened in desktop CAD software like AutoCAD or FreeCAD.

Why is my browser displaying the IGES file as raw text?

IGES files are typically ASCII-based, so if the server is misconfigured, it may send the file as text/plain. To prevent the browser from rendering the raw code, ensure your web server is configured to send the application/iges Content-Type header.

How do I add support for IGES files in Nginx?

You should modify your mime.types file or the types block within your nginx.conf. Add the following entry to map the extensions: application/iges iges igs;.

What is the difference between IGES and STEP files?

While application/iges is excellent for surface models and wireframes, STEP files are generally preferred for solid 3D models and preserving assembly hierarchies. IGES is an older standard (Legacy), whereas STEP is the modern successor for data exchange.

Is application/iges a binary or text format?

The application/iges MIME type usually refers to the ASCII (text-based) version of the format, which consists of 80-character fixed-length records. Although a binary version exists, the text-based format is the industry standard for interoperability.

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 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.
