Answer
The PLM uses an automatic engineering BOM (EBOM). This means every time you save an assembly the BOM will be created/updated on each 'claimed' or 'new' assembly node.
The BOM uses the positions and quantities of the instances in the CATIA tree, using a top-down approach.
Please note:
- Only CAD Documents identified as 'Master' 'Representation type' are automatically included in the BOM. See the full FAQ to understand how to manually add documents of alternative 'representation types'.
- The first instance of a reference found in the tree structure is what determines its position in the BOM.
- There are manual ways to override the CATIA positions & quantities, see the FAQ below.
You can also trigger a forced manual BOM synchronisation at any time from the “More” menu of the CAD Document profile card in the PLM platform.
