Daniel,
I've tested a prerelease version of pywin32 that contains the new
win32com.client.VARIANT class and it works well with AutoCAD. Once
released, you can write something like this:
import win32com.client
import pythoncom
def POINT(x,y,z):
return win32com.client.VARIANT(pythoncom.VT_ARRAY | pythoncom.VT_R8,
(x,y,z))
acad = win32com.client.Dispatch('AutoCAD.Application')
ms = acad.ActiveDocument.ModelSpace
ms.AddLine(POINT(0,0,0), POINT(1,1,0))
Additional information in Mark's original post on win32com.client.VARIANT:
