About Parts Lists and BOMs in iAssemblies

iAssemblies require custom views of parts lists and the bill of materials.

A Bill of materials shows one structured view for iAssemblies. The bill of materials contains the full aggregate list and item numbers for all members. If a member file is open, access to the bill of materials is not available. iAssemblies support only the First-Level Structured view. The All-Levels Structured view or the Parts-Only view is not available.

The structured iAssembly view is not member-specific, unlike the model data view. The structured view is common to all members.

For example, if you use Table Replace to reference different iPart members, each iAssembly member can have a different iPart member reference. These references appear as separate rows in the structured view with unique item numbers. If they are merged using part number merging, any column that varies per member shows "varies." QTY columns are specific to members. If an item quantity is zero for all members, it is not shown in the structured view.

Multiple assemblies can contain an iAssembly, and any instance, part, or assembly, can be excluded in the iAssembly. In the BOM, separate QTY and Item QTY columns display for each member as the item count is affected individually for members with component exclusion. A QTY override per member is available. Item QTY refers to a column choice that displays a calculated quantity for an item which is separate from a QTY for an item.

Note: You can edit a QTY for an item. The Item QTY is calculated and you cannot edit it.

A parts list can be created for selected members or for the whole iAssembly. An aggregate parts list of specified members is available. Only one bill of materials view containing the aggregate list of items and numbers is available.

Tip: You can edit the parts list and bill of materials to show specific member quantities.
