如何解决如何使用python保存和关闭AutoCAD应用程序？

我正在尝试保存并关闭AutoCAD应用程序。我尝试使用.Quit()，但没有用。

from comtypes import COMError
from comtypes.client import CreateObject,GetActiveObject


def main():
    # Capture opened AutoCAD
    try:
        acad = GetActiveObject("AutoCAD.Application")

    # Open new AutoCAD instance
    except (OSError,COMError):
        acad = CreateObject("AutoCAD.Application",dynamic=True)

    # Path to dwg file
    filepath = r"C:\test.dwg"  # Replace it with the actual drawing path
    doc = acad.Documents.Open(filepath)

    load_lisp = '(load "C:/DemoExtracao.fas") '  # Notice that the last SPACE is equivalent to

    doc.SendCommand(load_lisp)

    execute_lisp = "(DEMO) "

    doc.SendCommand(execute_lisp)
    
    doc.Quit() # This line doesn't work


# Início da aplicação principal
if __name__ == "__main__":
    main()
