CATIA macro from python

问题:

I would like to use my macro (.CATScript) to open the catia interface and make the changes listed in the macro script to the .CATpart and give output as .stp file. Is it possible to use python to realise this function?

There was an example in Run a Catia macro with a python script, but it didn't work in my case. I edited the code as below and gave it a run.

import win32com.client catapp = win32com.client.Dispatch("CATIA.Application") catapp.StartCommand('Macro_schweller_model_lsopt.CATScript') 

The error I had was

File "C:\FK-Programme\python36-32\Anaconda\Install\lib\site-packages\win32com\client\dynamic.py", line 91, in _GetGoodDispatch     IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch)  com_error: (-2147221005, 'Ungültige Klassenzeichenfolge', None, None) 

My .CATscript looks like this

Sub CATMain()      Dim FileToOpen as String     Dim partDocument1 As Document     Dim part1 As Part     Dim AnglePara As Parameter     Dim parameters1 As Parameters     Dim AmplitudePara As Parameter     Dim WavelengthPara As Parameter      FileToOpen = "E:\Datei\Results\Optimization\LS_OPT_results\Optimization_model_1\Schweller_fully_corrugated.CATPart"      Set partDocument1 = CATIA.Documents.Open(FileToOpen)      Set part1 = partDocument1.Part      Set parameters1 = part1.Parameters      Set AnglePara = parameters1.RootParameterSet.DirectParameters.Item("Angle")      AnglePara.Value = -7      Set AmplitudePara = parameters1.RootParameterSet.DirectParameters.Item("Amplitude")      AmplitudePara.Value = 30      Set WavelengthPara = parameters1.RootParameterSet.DirectParameters.Item("Wavelength")      WavelengthPara.Value = 30      CATIA.DisplayFileAlerts = False      partDocument1.Part.Update      partDocument1.ExportData "E:\Datei\Results\Optimization\LS_OPT_results\Optimization_model_1\Schweller.stp", "stp"    End Sub

The StartCommand method can (as far as I know) only start macros assigned to toolbar buttons. I advise you to instead use the SystemService.ExecuteScript method, which allows you to run the script directly. Your example would then be modified to look something like this:

import win32com.client catapp = win32com.client.Dispatch("CATIA.Application") catapp.SystemService.ExecuteScript(     # Macro library name/path     r"C:\Path\To\Directory\Containing\The\Script",     # Type of macro library (document/directory/VBA project)     1,  # directory     # Macro name     "Macro_schweller_model_lsopt.CATScript",     # Function name     "CATMain",     # Arguments     tuple(), ) 

More information on the SystemService.ExecuteScript method is available at http://catiadoc.free.fr/online/interfaces/interface_SystemService.htm#ExecuteScript.
