Ok, that's "interesting". I have a VMWare image that I have available
for testing installations so it is a clean machine to start with. I
installed AutoCAD 2004 and Python 2.5.2 and comtypes 0.5.1 on there
and all works as expected. Installing and uninstalling comtypes on my
personal machine makes no difference. I suspect the problem is my
installation of AutoPLANT which sits on top of AutoCAD -- but pywin32
seems to have no difficulty with it and I really need that for my work
so I can't simply uninstall it. Why AutoPLANT would cause
difficulties, though, I'm not sure. There seemed to be some difference
in how the generated class was built so I copied the generated file
from the working machine to my own machine but that made no
difference. It seems like what is happening is that
app.ActiveDocument.ModelSpace is actually returning app.ActiveDocument
for some reason so its obvious then why no such interface is
supported. But why the property for ModelSpace is returning the
document I have no clue. Any further suggestions on how to figure this
out?
