发生错误： (-2147352567, '发生意外。', ('无法获取 Document 对象', 'AutoCAD', 'C:\Program Files\Autodesk\AutoCAD 2020\HELP\OLE_ERR.CHM', -2145320900, None))

My code: from pyautocad import Autocad, APoint

尝试连接到已经运行的AutoCAD实例

acad = Autocad(create_if_not_exists=True)

检查是否成功连接到AutoCAD

if acad: try: acad.prompt("Hello, Autocad from Python\n") print(acad.doc.Name)

    p1 = APoint(0, 0)
    p2 = APoint(50, 25)
    for i in range(5):
        text = acad.model.AddText('Hi %s!' % i, p1, 2.5)
        acad.model.AddLine(p1, p2)
        acad.model.AddCircle(p1, 10)
        p1.y += 10

    dp = APoint(10, 0)
    for text in acad.iter_objects('Text'):
        print('text: %s at: %s' % (text.TextString, text.InsertionPoint))
        text.InsertionPoint = APoint(text.InsertionPoint) + dp

    for obj in acad.iter_objects(['Circle', 'Line']):
        print(obj.ObjectName)
except Exception as e:
    print("发生错误：", e)

else: print("无法连接到AutoCAD")
