hello，i need your help.
i read your doc and try to use other function referening AutoCAD ActiveX documentation.
but find some error,however the function did work.
here is the codes（quite simple）:

#---------------------------------------------------------------------------
from pyautocad import Autocad, APoint
acad = Autocad(create_if_not_exists=True)
p1 = APoint(0, 0, 0)
p2 = APoint(25, 0, 0)
p3 = APoint(60, 60)
line = acad.model.AddLine(p1, p2)
offset = line.Offset(12)

#---------------------------------------------------------------------------
and here is the message:

D:\pythonWorkSpace\first_folder\Scripts\python.exe D:/workspace/first_python/manipulate_cad/TestCad.py
Traceback (most recent call last):
File "D:/workspace/first_python/manipulate_cad/TestCad.py", line 14, in
offset = line.Offset(12)
File "D:\pythonWorkSpace\first_folder\lib\site-packages\comtypes\client\lazybind.py", line 182, in caller
return self._comobj._invoke(descr.memid, descr.invkind, 0, *args)
File "D:\pythonWorkSpace\first_folder\lib\site-packages\comtypes\automation.py", line 730, in _invoke
return var._get_value(dynamic=True)
File "D:\pythonWorkSpace\first_folder\lib\site-packages\comtypes\automation.py", line 457, in _get_value
typ = _vartype_to_ctype[self.vt & ~VT_ARRAY]
KeyError: 9

Process finished with exit code 1

#---------------------------------------------------------------------------
the same error occured when i use '' line.ArrayPolar(3, 3.14, p1)''
But just as i said, auto cad did work well and draw the graphics rightly.
How can i settle this? I need your help.
By the way ,the version of my auto cad is 2018.
Thanks~!
