The BomRow object is of type PsObject and represents an individual line item in a BOM of a specific Fusion 360 Manage Item.

The $bomRow object is dynamically created depending on the defined Custom BOM fields which are assigned to a View in the Bill of Materials Tab and additionally provides all the members from the corresponding Item.

The BOM specific properties have the same name as the BOM Fields in Fusion 360 Manage starting with the ‘Bom_’ prefix (regardless of the used display names in the different BOM Views).
Properties that include whitespaces can be accessed by enclosing them in single quotes.



The following Standard BOM fields are always available in addition to the Item members:






The line number of the item in the BOM



The quantity of the item in the BOM



The Unit Abbreviation value of the BOM line item (e.g. EA, kg, mm,…).

The Unit of Measure property on the according Item returns the full Unit name instead.”


Similar as for Item Fields, the Custom BOM field properties are converted to a corresponding PowerShell data type based on the configured Field types in Fusion 360 Manage.


Example of a single line item in BOM of Item ‘699-00001 - p681 GeForce GT210’:
