If I open assembly of "K" and resolve components using (_ModelDoc (AssemblyDoc)).ResolveAllLightWeightComponents (false),  components resolved very quickly. If I first open the drawing document ,using the same elements as assembly of "K", search  all views and  resolve assemblies in views using SetLightweightToResolved(). Components of assemblies resolved very slowly, why so?
