File format information for 3DM to OFF

Extension: 3DM

Full Name: Rhinoceros 3D

Type: 3D Model

Mime Type: x-world/x-3dmf

Format: Binary

Description

The 3DM format also known as Rhino3D or Rhinoceros 3D is a 3D graphics model file format developed and used in CAD applications, Industrial Design and 3D Printing. The format has some compatibility with Adobe Illustrator and can be exported as an AI file using vector graphics.

Although it is a 3D file format it stores data in the NURBS geometry format which allows for greater mathematically precision compared to triangle/polygon based mesh geometry formats such as STL. Along with support for converting between other CAD formats the 3DM format can also supports two different scripting languages.

3DM Notes

If your 3DM file contains textures, these will be ignored. If a material contains color information this will be translated where possible.

Supported Features

  • Mesh geometry
  • Mesh material colors

Unsupported Features

  • Textures
  • Animations

Extension: OFF

Full Name: Object File Format

Type: 3D Model

Mime Type: text/plain

Format: Text

Description

The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shape, edge information and also has support for including color information. As the format is text based the files can become rather large with no built-in compression options available.

OFF Notes

OFF files support per face color information. If your uploaded model contains color information our tool will attempt to save this in the OFF file at the end of the conversion process.

Supported Features

  • Mesh geometry
  • Face colors
