What is .3dm?

.3dm is a file extension used by Rhino 3D modeling software. It stands for "Rhino 3D Model" and contains 3D models and designs created within the Rhino program. The file format is proprietary to Rhino and is not compatible with other 3D modeling software unless they offer support for importing/exporting .3dm files. The .3dm file format is used in various industries such as industrial design, architecture, engineering, product development, and more. It supports NURBS (Non-Uniform Rational B-Splines) curves and surfaces which allows for precise and flexible modeling of complex shapes.
