Product Structure (BOM)
Definition
A product structure, also known as a bill of materials (BOM), hierarchically describes the composition of a product.
Product structures are created, for example, when assemblies are modeled in Vertex G4 or SolidWorks, using existing items or creating new items to represent parts or subassemblies.
A product structure can also be created in Flow and later have its geometry designed using CAD software.
In the item structure of a part model, the raw material (raw material item) serves as a substructure for the part.
Items representing purchased components typically do not have a structure. They are represented only by an (inventory) item used to identify the component.
