There is currently no easy way to copy design an assembly that contains a Tube and Pipe assembly. Currently, the easiest way to accomplish this is to perform the copy design in Vault and set the Tube and Pipe subassembly to "Reuse". Once the copy design is complete, open the new assembly in Inventor and copy the Tube and Pipe assembly. Paste a second copy of the Tube and Pipe assembly into your new assembly and constrain it to the origin planes. Delete the original instance of the Tube and Pipe assembly to clear adaptivity. Right click on the second (now only) instance of the Tube and Pipe assembly and select Make Adaptive. This will initiate Inventor to save a copy of every sub-component of the tube and pipe assembly with the correct naming convention to match your new assembly file name.
There are several problems with this method:
1. The Tube and Pipe assembly being copied and all of its children must be checked out from the Vault prior to selecting Make Adaptive. If it is going to Save As and replace all parts why does it need the original checked out? This creates issues when users forget to go back and Undo Check Out on the original Tube and Pipe assembly since it is no longer a part of the open assembly and doesn't show up in the model tree.
2. All fittings connections are lost. There needs to be a way to copy the Tube and Pipe assembly without losing all fittings connections. Since the Tube and Pipe assembly was constrained to the origin prior to the Make Adaptive everything appears to be connected correctly but all of the connections are gone.
