File format information for 3DM and STL

Extension3DM
Full NameRhinoceros 3D
Type3D Model
Mime Typex-world/x-3dmf
FormatBinary

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 Converter Capabilities

Our 3DM 3D Model/Mesh tool does not support any color material data contained within 3DM files so the converted file will not contain any color information.

ExtensionSTL

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

STL Converter Capabilities

Our 3D conversion tool does not support color/material information in STL files so your file will not contain any color information.

Information for converting from 3DM to STL

Your 3DM file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our 3DM 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. Our tool will not attempt to transfer any color information if present in your 3DM file, your final 3D model will contain geometry data only.
