A 3DM file is a native file format for 3D models in Rhinoceros CAD application software. It contains surface, point and curve information.
3DM files can be exported in both NURBS (non-uniform rational B-spline) and polygon mesh representations, making it possible for other CAD / CAM / CAE / graphic design software to edit those models.
In addition to Rhino CAD software, 3DM files can be opened with Autodesk Fusion 360.
A PRT format is used to store components of 3D CAD models. It may contain lines, surfaces, textures, dimensions, and metadata.
The .prt extension is mostly associated with the Siemens NX Part (PRT) file type as an acronym for "part". PRT files may be exported to various standard CAD and 3D modeling formats (e.g. OBJ and STL) in addition to being utilized natively in Siemens NX.
The PRT file is also a part created by PTC Creo Parametric 3D software. In PTC Creo, project part files can be combined in a single assembly file with an ASM extension.
Despite the same extension name different CAD software produce PRT files differently, i.e. PRT files produced with Creo are not the same as PRT files generated from NX.
The PRT extension is also compatible with Dassault Systèmes SOLIDWORKS.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
