rhino3dm

rhino3dm is a set of libraries based on the OpenNURBS geometry library with a "RhinoCommon" style. This provides the ability to access and manipulate geometry through .NET, Python or JavaScript applications independent of Rhino.

Functionality includes

Create, interrogate, and store all geometry types supported in Rhino. This includes points, point clouds, NURBS curves and surfaces, polysurfaces (B-Reps), meshes, annotations, extrusions, and SubDs.
Work with non-geometry classes supported in Rhino like layers, object attributes, transforms and viewports
Read and write all of the above information to and from the .3dm file format
Use as a client to make calls into the Rhino Compute cloud server for advanced manipulation of geometry objects
Available on most platforms (Windows, macOS, Linux)
