🔺 How to convert Mesh files to 3DM? Choose files and upload them on the page. Select 'to 3DM' and click 'Convert'. After a few seconds, you can download 3DM files. 3DM file is an OpenNURBS 3D Model. The openNURBS Initiative provides CAD, CAM, CAE, and computer graphics software developers the tools to accurately transfer 3-D geometry between applications. The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned 3dm to pdf.

What is a 3DM file?
A 3DM file is an open-source 3D model format and native file format for Rhinoceros. It contains a 3D model which includes surface, points, and curve information. 3DM files allow CAD, CAM, CAE, and computer graphics software to accurately save and exchange 3D geometry using both NURBS and polygon mesh representations.
The 3DM open-source library is available at www.opennurbs.org/.

| Description | The Rhinoceros file format (.3DM) is useful for the exchange of NURBS geometry. The Rhino developers started the openNURBS Initiative to provide computer graphics software developers the tools to accurately transfer 3-D geometry between applications. An open-source toolkit, openNURBS includes the 3DM file format specification, documentation, C++ source code libraries and .NET 2.0 assemblies to read and write the file format, on supported platforms (Windows, Windows x64, Mac, and Linux). | STL is a file format native to the stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages. It is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact. |
| Technical details | An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary. | |
