how do you prevent the reuse of reference designators of components that you deleted

Yokem Yelom

I'm in layout and I'd like to prevent the reuse of reference designators of components that I deleted.  Can I use the Tools -> Annotate -> Advanced Annotation -> Preserve user assigned valid references?

    You can use 'Incremental Reference update' from Tools > Annotate.

    For ex: If R1, R2, R3 and R4 are there. You deleted R2. Now you place one more resistor and you don't want this resistor to have refdes as R2 but R5. You can use 'Incremental Reference update' from Tools > Annotate.

    Hope it helps! Let me know if it works for you or if you have any further issue regarding this.

    There's still the problem when you delete R5 and use the incremental reference update that R5 will be reused.

    Incremental annotation works this way. It looks for last assigned designator for any prefix and start assigning from there for upcoming part on schematic. If user deletes R5, then R4 becomes automatically the highest number of designator and for next part, it starts assigning from +1.

    It won't do hole filling. If R2 or R3 gets deleted then they will not be assigned for any upcoming part.

    Hope it clarifies!

    Thanks for the response.  This would be a nice feature to add.

    Just to be clear there is no automated CIS solution.
