将 python 连接到 Autocad 的问题

Question

我目前正在 Python 中使用

AutoCAD

，最近尝试在 Python 和 AutoCAD 之间建立连接。我写了一个简单的脚本来测试连接：

from pyautocad import Autocad

def main():
    # Create an instance of AutoCAD
    acad = Autocad()

    # Check if there's an active document
    print(acad.doc.Name)

if __name__ == "__main__":
    main()

但是，我遇到了以下错误消息：

Traceback (most recent call last):
  File "C:\Users\engli\PycharmProjects\pythonProject\Architecture\create a line.py", line 12, in <module>
    main()
  File "C:\Users\engli\PycharmProjects\pythonProject\Architecture\create a line.py", line 8, in main
    print(acad.doc.Name)
          ^^^^^^^^
  File "C:\Users\engli\PycharmProjects\pythonProject\.venv\Lib\site-packages\pyautocad\api.py", line 74, in doc
    return self.app.ActiveDocument
           ^^^^^^^^

    self._app = comtypes.client.GetActiveObject('AutoCAD.Application', dynamic=True)
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    clsid = GUID.from_progid(progid)
            ^^^^^^^^^^^^^^^^^^^^^^^^

  File "_ctypes/callproc.c", line 1008, in GetResult
OSError: [WinError -2147221005] Invalid class string

错误消息

Invalid class string

表明无法找到或访问 AutoCAD 的 COM 对象。我不确定如何解决这个问题。任何帮助将不胜感激。

您有完整版的 AutoCAD 或 AutoCAD LT 吗？
