What is a reused assembly?

Manufacturing needs are often different from design needs, and the engineering design is created in a CAD package that sometimes cannot be changed by manufacturing personnel. Manufacturing engineers often need to create a manufacturing subassembly in an MBOM from parts in an EBOM. They then need to align the assigned parts in the MBOM with those in the EBOM.

If parts are added to the EBOM that are reused multiple times in the MBOM, such as chair parts in this example, you can update the MBOM by copying those parts to a single reusable assembly. If the same sets of parts in the reusable assembly exist in the EBOM multiple times and are located and oriented in a repeated pattern relative to each other, you can create a reusable assembly from those parts in the MBOM. You can then search the EBOM for other collections of the same parts and patterns and add the same assembly to the MBOM for each collection. Those parts share the same item ID or part number, thereby reducing your inventory and the complexity of your manufacturing process. The reused assemblies are automatically aligned with the EBOM and transformed in the graphical view.

Note

• If the reusable parts all exist at the same location (for example, 0,0,0), they are ignored.

• Welds, mirrored transforms, and scaled transforms are not supported.

• Patterns in which the same part could exist in multiple assemblies—such as a line of five parts that are ten inches apart and a subassembly that contains two parts ten inches apart—are not supported. All possible combinations that match the reusable assembly's pattern are returned in the search.

• Parts in the EBOM that are configured out using variants, effectivity, and other overrides are still considered when you create a reusable assembly.

• If you have a second EBOM with parts copied from an original EBOM, they share the same in-context IDs (IDICs). If you set the second EBOM as the scope to be used in an MBOM assembly reused from the original EBOM, Teamcenter will searches and returns found parts in a collection from the second EBOM.
