Hi Marsel,

thanks for your reply. I can now compile the sample plugin, and it is copied to plugins/MaxDotNet folder after compiling the project. But 3ds Max does not load the Plane plugin, e.g. there's no "Max.NET Tutorial" category inside the Geometry rollout.

In the Plugin Manager, the AUTODESK.MAX.WRAPPERS.DLU is successfully loaded, but where's the Plane.dll? There are no error messages or something like that at startup. So how can I get Max.NET to load the Plane.dll?

Thanks again,

Christian

Ok, I found out now that I have to specify the plugin path in the plugin.ini:

[Directories]
Max.Net Plugins=C:\Program Files\Autodesk\3ds Max 2009\plugins\MaxDotNet

Seems that in previous versions, the MaxDotNet path was used by default. I guess you need to upgrade your tutorials, too :)
