About collaborative designs in manufacturing

When you use 4th Generation Design (4GD) to author design data, you can assign or consume this data in a manufacturing representation of the data that is based on a BOM view revision structure. Teamcenter can bridge the gap between the two data models to allow you to perform accountability checks and propagate attributes from a collaborative design to a manufacturing structure (MBOM).

Note

The term MBOM refers to a structure that is based on BOM view revisions and not on a collaborative design.

When developing the MBOM, the manufacturing planner performs some of the following tasks:

Authors manufacturing assemblies in the BVR structure, while consuming design elements from the collaborative design.
Adds provisional elements (placeholders) for parts not yet defined in the collaborative design.
Adds nongeometrical elements to assemblies, for example, consumable raw material not modeled in CAD such as glue, oil, or water.
Restructures assemblies by moving parts from one manufacturing assembly to another.
Decomposes assemblies into subassemblies for creating kits.

Multi-BOM Management includes the Content Explorer as well as supports secondary views to view 4GD data without leaving the application. You can only load a subset definition as root into this view. You cannot load a collaborative design, a design element, or a workset as root. Loading a subset definition allows you to logically and flexibly slice the product (the collaborative design) into manageable sections (the recipe) and to use this definition to assign into the MBOM. At any point, you can view which parts (design elements) and manufacturing features (design features) have not been assigned or updated by activating the accountability check between the subset definition and the MBOM. The rich recipe query in a subset definition enables you to specify the logical representation of the product subset which dynamically displays the most updated product subset.

The general workflow for working with collaborative design data in manufacturing is as follows:

Create a 4GD subset definition in the Content Explorer that represents the scope of the design elements that must be included in the manufacturing BOM.
Open the subset definition in the Multi-BOM Management application.
Create a BOM structure to represent the manufacturing BOM.
Assign design elements from the subset definition to the MBOM with the goal of assigning all relevant design elements to the MBOM.

Note You can only assign design elements to precise BOM view revisions.

Use the MBOM to support process structures and downstream integrations.
After changes are made to the design, compare the design structure to the MBOM using an accountability check to find differences and propagate these differences to the MBOM where necessary.
