Can anyone with .NET 2.0 Runtime and a version of AutoCAD greater than 2005 installed test an assembly for me? I compiling against the 2005 versions of the managed dll files and am wondering if anyone else can use them, mainly since the method of writing to the command line has changed between 2005 and future versions.
To Run:
* netload the PyAcadDotNet.dll
* issue the pyfile command
* browse to the folder you unziped to and select print.py
If you see a bunch of text strings dumped onto the commandline then it worked. If not please let me know. I'm doing some trickery to automatically add the AutoCAD managed dlls as references in python so that may be screwing things up.
Here is the source code for the dll if anyone is interested.
