The Sync command copies the item numbers of the *Structured* BOM view of the current (main) assembly to the *Structured* BOM view of the subassemblies.

{% hint style="info" %}
This command modifies components' item numbers in subassemblies.
{% endhint %}

{% hint style="warning" %}
This command is to be run in the main assembly only.
{% endhint %}

## Description of changes performed by the command

In the *Structured* BOM of the main assembly, components 004, 005, and 006 have item numbers 4, 5, and 6 (after the dot symbol). Item numbers of components 004, 005, and 006 in the structured BOM view in subassembly 010 are 1, 2, and 3.

After running the command, structured numbering in the subassembly matches the structured numbering (behind the dot symbol) of the main assembly. The subassembly file is physically modified by the command.
