Spaceclaim ACT 中报错Cannot import name GetAllBodies

[maruidiyi2]

当我在spaceclaim中建立一个script，它是可以正常运行的。但是当我尝试建立一个wizard来封装script时，程序无法运行。在log文件中显示

Error when invoking function 'QFN'.
Traceback (most recent call last): 
File "D:\0插件库\spaceclaim\ACT\SoledrjointGen\SoledrjointGen\SolderjointGen_main.py", line 717, in QFN 
StandardError: Exception has been thrown by the target of an invocation.
Traceback (most recent call last): 
File "D:\0插件库\spaceclaim\ACT\SoledrjointGen\SoledrjointGen\SolderjointGen_main.py", line 717, in QFN 
ImportError: Cannot import name GetAllBodies

我已经在py文件的开头进行以下声明
import os, sys
clr.AddReference("Ans.Utilities")
from Ansys.Utilities import ApplicationConfiguration
version = ApplicationConfiguration.DefaultConfiguration.VersionInfo.VersionString
 
sys.path.append(os.environ["AWP_ROOT"+version]+"/scdm/Scripting")
clr.AddReference("SpaceClaim.Api.V20".format(version))
clr.AddReference("SpaceClaim.Api.V20.Scripting".format(version))
exec('from LoadSCDMAPITypesV20 import *'.format(version))
exec('from UtilitiesOnLoadV20 import *'.format(version))
有人知道为什么吗？
