Good day.
A non-systemic (random) error occurred while calling SetAutomaticKutList of one part in different configurations.

The macro works, but only with swModelPart.Visible = true enabled. But this greatly increases the execution time of the macro. Whoever encountered this, please help me fix the code without swModelPart.Visible = true.

Code below

swModel = (ModelDoc2)swApp.ActiveDoc;

AssemblyDoc swAssy = (AssemblyDoc)swModel;
swAssy.ResolveAllLightWeightComponents(true);
Object[] vComps = swAssy.GetComponents(false);

for (int i = 0; i < vComps.Length; i++) 
{
   swComp = (Component2)vComps[i]; 
   NameswComp = swComp.GetPathName();
   if (swComp.IsSuppressed() == false)
   {
      NamePart = GetName(NameswComp);
      configName = swComp.ReferencedConfiguration;
      if (NamePart != "")
      {
         swModelPart = swComp.GetModelDoc();
         Feature swFeat = swComp.FirstFeature();
         while (swFeat != null)
         {
            if (swFeat.GetTypeName2() == "SolidBodyFolder" & NameswComp.ToLower().IndexOf(".sldasm") == -1)
            {
               SolidBodiFolder = swFeat;

               swModelPart.Visible = true; <<<<<<<<<<<<<<<<<<               swBodyFolder = (BodyFolder)swFeat.GetSpecificFeature2();
               boolstatus = swModelPart.ShowConfiguration2(configName);
               boolstatus = swBodyFolder.SetAutomaticCutList(true); <<<<<<<<<< Does not give an error
               boolstatus = swBodyFolder.UpdateCutList();
               boolstatus = swBodyFolder.SetAutomaticCutList(false);

               swModelPart.Visible = false; <<<<<<<<<<<<<<<<<<<How to get rid of this ???
               swApp.CloseDoc(NameswComp);
               break;
            }
            swFeat = swFeat.GetNextFeature();
         }

      }

   }

}

It works only with a visible part window. But that doesn’t suit me???
