You can use the Transfer command to transfer a tube to a new or existing assembly. When you transfer a tube, the system copies the path for the tube into the target assembly and creates an associative link between the tube and the copied path. The path in the target assembly is not associative to the path in the source assembly, so you can edit the new path without affecting the path in the source assembly.
All of the parameters of the tube are copied to the new assembly.
Any relationships applied to the path segments in the source assembly are reestablished in the target assembly. If the part that contains the port remains below the target assembly, the relationships are reestablished. If the part that contains the port is transferred to an assembly that is not below the target assembly no warning is displayed and the associativity of the port is broken. You can use the Hide Previous Level command to make sure the part containing the port is below the target assembly. To do this, in-place activate into a subassembly and select the Hide Previous Level command. If you can see the part in the graphics window, it is at the current level or below in the tree structure. If the part disappears when you select the Hide Previous Level command, the part is above the active assembly level. If you want to move the tube down the tree structure, make sure that the port part will remain at or below the target level. If the target assembly is below the current level of the port part, you should transfer the port part to the level of the target assembly before transferring the tube.
If the tube being transferred refers to sketch elements, a new sketch is created in the target assembly. The sketch will contain only the 2D elements referenced by the tube being transferred.
