Overview

Characteristics

Rhinoceros is primarily a freeform surface modeler that utilizes the

mathematical model. Rhinoceros's application architecture and open SDK make it modular and enable the user to customize the interface and create custom commands and menus.

File formats

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.

Compatibility

Rhinoceros offers compatibility with other software as it supports over 30 CAD file formats for importing and exporting. The following CAD and

image file formats An Image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be ...

Rhinoceros's import and export modules are actually plug-ins, so they can be easily updated via a service release. Rhinoceros Service Releases (SR) are frequent and freely downloadable. Rhinoceros 5 SR10 can import and export DWG/DXF file formats up to version 2014.

3D printing

Rhinoceros 3D relies on a few plug-ins that facilitate 3D printing and allows the export of .STL and .OBJ file formats, both of which are supported by numerous 3D printers and 3D printing services.
