Dear 孔欣驰,
I might be wrong, but your question is more related to autoCAD rather than
comtypes. In particular the use of "hatch.AppendOuterLoop([circle])" method.
What type of arguments does it take? Could it be that the argument types you
are passing are inappropriate?
What "circle" contains i.e. is it a list or an object?
Try "hatch.AppendOuterLoop(circle)"
or
"hatch.AppendOuterLoop([circle, ])".
Just shooting in the dark. I would suggest you reading the "AppendOuterLoop"
method description.
Cheers,
Alkin
