Updating Aligned Engineering BOM
Update an engineering BOM by dragging a design occurrence to a part occurrence
Procedure
Set an active change, if required.
Search for the required design structure (design revision) and open it.
Click Align > Open Alignment View.
The design structure and the engineering BOM (Usage BOM or Assembly BOM) are now displayed side by side.
Drag a design occurrence to a part occurrence.
In the displayed dialog box:
- Select the Run in Background check box if you want to move on to other tasks while the engineering BOM is updated. You will be notified in Alerts once the engineering BOM is updated.
- Click Generate.
An aligned part occurrence is created under the part where you dragged the design occurrence to.
Results
A report is generated in the Newstuff > BOMGeneration folder. You can go through the contents of the report to troubleshoot any part occurrence creation and alignment issues. You can also perform an alignment check to verify if the design occurrences and part occurrences are aligned correctly.
