[python-win32] problem AddLine AutoCAD win32com.client

[Mark Hammond]

Re-added the python-win32 list - please keep replies on list.

Your code uses:

 >         pt1 = array.array('d', [0.0,0.0,0.0])
 >         pt2=array.array('d',[1.0,1.0,__0.0])

But these aren't supported by pywin32 in the way you expect - what 
happens if you change this to:

          pt1 = [0.0,0.0,0.0]
          pt2 =[1.0,1.0,0.0]

?
