python - pyautocad 给出不可谷歌的错误

Question

OSError: [WinError -2147221005] Invalid class string

完整的回溯

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/MONSTR/Desktop/Ванжые/Yusuf bey/GUI/test1.py", line 10, in <module>
    for text in acad.iter_objects('Text'):

当我尝试从 here 编译此代码时，出现此错误

from pyautocad import Autocad, APoint

acad = Autocad()
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)

在谷歌上搜索了几个小时后，我决定在这里思考
可能是什么原因？

发生该特定错误是因为您的程序无法正确打开 AutoCAD；但是当我自己打开AutoCAD然后运行你的代码时，出现以下错误:

_ctypes.COMError: (-2147467262, 'No compatible interface', (None, None, None, 0, None))

根据我的经验，COMError 经常由于与所使用的程序的连接不良而出现。我通过将 win32com 与 pyautocad 结合起来解决了此类问题。对于这个特殊情况，它会是这样的:

from pyautocad import Autocad, APoint
import win32com.client

AutoCAD = win32com.client.Dispatch("AutoCAD.Application")
acad = Autocad(create_if_not_exists = False)

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(['Hi']):
    print('text: %s at: %s' % (text.TextString, text.InsertionPoint))
    text.InsertionPoint = APoint(text.InsertionPoint) + dp

for line in acad.iter_objects(dont_cast = True):
    print(line.ObjectName)

AutoCAD.Visible = True
