Troubleshooting

Note that when Rhino is in headless mode there is no document defined. The static property RhinoDoc.ActiveDoc will thus be null which may trip up your plugin code.
If you have any problems getting this to work or you have a more complex use case, then please get in touch via the issue tracker.
