Managing part BOMs
Align a part BOM using a smart search
While you can manually apply heavy or light alignments to part BOMs from CAD BOMs, you can also search for design objects based on a variety of attribute criteria that exists in the system or is defined by your administrator, and create heavy or light alignments based on search results:
If you never aligned part/CAD BOM items before.
If you previously aligned them but the alignment somehow became broken.
Procedure
Decide whether you want to perform a heavy or light alignment.
Right-click a part in the part BOM and choose Search for Design and Create Heavy Alignment or Search for Design and Create Light Alignment.
In the Create Heavy Alignment to Design or Create Light Alignment to Design dialog box, any CAD BOM objects found to share attributes in common with the selected part object in the part BOM are displayed.
Click Set/Add current selection to align the objects.
For the current session only, if you want to search for other matching objects and want to automatically align the objects if a single exact match is found, select the Do not show this dialog again for single exact matches check box, and then click OK.
A message is displayed reporting that the CAD and part objects are aligned.
- If you would rather not see this message again while aligning other objects, select the Do not show this warning again in the session check box.
