pyautocad给出了难以合理的错误

Question

Oserror：[WinError -2147221005]无效类字符串

全追溯

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'):

  File "_ctypes/callproc.c", line 918, in GetResult
OSError: [WinError -2147221005] Invalid class string

当我尝试从此处编译此代码

时，我会遇到此错误

from pyautocad import Autocad, APoint
acad = Autocad()
acad.prompt("Hello, Autocad from Pythonn")
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Google上几个小时后，我决定在这里想知道
原因是什么？

发生特定错误，因为您的程序无法正确打开自动加速；但是，当我自己打开AutoCAD然后运行您的代码时，它会出现以下错误：

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

根据我的经验，COMError通常是由于与二手程序的联系差而出现。我通过将win32com与pyautocad相结合来解决此类问题。对于这种特殊情况，这将是这样的：

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
