Thanks for the suggestion. I tried clearing the gen directory in
site-packages/comtypes and no dice. The code in question that I am
using is the sample code from the web site but I'll post it here again
just for clarity:

app = comtypes.client.GetActiveObject("AutoCAD.Application")
modelSpace = app.ActiveDocument.ModelSpace

This is using AutoCAD 2004. I don't have a copy of AutoCAD 2008 to try
currently. Do you have a copy of AutoCAD 2004 that you could try?

Thanks for your help so far.

Anthony
