The Reset Part / Sheet Symbol Unique IDs dialog

Summary

This dialog allows you to reset the Unique IDs for Parts and Sheet Symbols.

The component UID is used to link each schematic component to its PCB component. If these are reset, you will need to re-establish the link, which can be done at any time by selecting the Project » Component Links command in the PCB editor. This command updates each PCB UID to match the current schematic UID. Note that when the UIDs are not matching, the software relies on the designators instead, therefore, these should be matching before resetting schematic component UIDs.

Access

The dialog is accessed from the schematic editor by clicking Tools » Convert » Reset Component Unique IDs from the main menus.
