Before a parts list is created, you must enable structured and parts-only bill of materials (BOM) views in the BOM Editor. As with normal Autodesk Inventor components, library fittings from the same part family are always rolled up together in parts lists since they have the same part number. However, conduit parts behave differently.
In the current version of Autodesk Inventor, conduit item rows in parts lists are not grouped by default. In either drawing templates or specific drawing documents, you can enable the grouping and determine a sequential order of keys to accomplish the grouping. For instance, set the first grouping key to the raw material property (Stock Number).
By default, conduit parts have an empty part number but they may need to be designated as separate components. Though the parts list grouping does not apply to invisible items and items with blank properties, but two drawing properties are typically used to roll up parts lists correctly specifically in a drawing document or universally in drawing templates:
Parts lists are generated from BOM views. Typically, changes to item numbers in BOM views are automatically reflected in the parts lists. To update BOM views when changes are made to item numbers in the parts list, you can manually override the item quantities in BOM views.
When working with drawing documents of a tube and pipe iAssembly factory, you can create a parts list of selected members or a traditional single assembly parts list. You can also create an aggregate parts list of specified members. However, only one BOM view is provided containing the aggregate list of items and item numbers.
By default, the parts list is created based on the active assembly member. To select all or other members, you must edit the parts list at a later time. Separate QTY and Item QTY columns exist as each members item count are affected individually for members with component suppression.
