Max.NET is a .NET CLR wrapper for 3d Studio Max's (3dsmax) software development kit (SDK). It allows developers to write tools for 3dsmax in a managed and reflective environment using any of the common .NET languages such as C#, VB.net, J#, and C++/CLI. Moreover it provides access to all of the classes and their members accessible to normal unmanaged SDK.
