The advent of IronPython allows Python programmers to explore Microsofts .NET framework in a dynamic way. It also allows Python programmers to explore AutoCAD's .NET interface in a dynamic way. Pyacad.NET is an attempt to program AutoCAD via it's .NET interface with IronPython.
At this point in time Pyacad.NET is more of a proof of concept than anything else. Don't expect to be able to write production ready code with this software.
If you're interested in working on this project you can access the code via the subversion repository. You can also email me for write access to the repository.
You can take a look at some of the samples here.
