The 3DM file format is a 3D Computer Aided Design (CAD) format primarily used by the Rhinoceros CAD software. It enables the storage of both simple and complex 3D models within a standard package and has found many uses within the architectural, engineering, and manufacturing arenas.
The format allows the storage of 3D model geometric data, including mesh and texture coordinate data. This 3D data is stored in the NURBS format, allowing complex objects to be represented with high precision.
Although primarily designed for use with the Rhinoceros CAD software, 3DM files enjoy support amongst other CAD software, with many supporting the import and export of data to the format.
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.
The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.
STL files come in two flavors: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.
The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.
STL Converter Capabilities
Our 3D conversion tool does not support color or material information in STL files, so your file will not contain any color information.
