Hi,
I have a hydraulic module which contains some valves, pipes, hoses etc. If a drawing is created for this, all the components will be floating which is not the right way to represent. So I need few other modules(sub assemblies) for reference where this hydraulic module will be mounted to. But the tricky part is I do not need these reference modules to be visible/duplicated when the hydraulic module is called in a top level assembly (as the top level assembly already have these modules). Please suggest any techniques to over come this, we did tried a bit with Shrink wrap, Envelop with skeleton but we are still learing this and not able to find the solution.
