Hello, I have an assembly with multiple sub assemblies.  The sub assemblies have tube routes which reference geometry in the main assembly.  Whenever I add/manipulate/remove components these sub assemblies like to get rebuild errors.  To fix these errors I am forced to go through each sub assembly and save/rebuild them.

I was wondering if there is a more dependable way to route my assembly.  Should I bring all of my routing to the main assembly?
