#1 Best approach for modifying a system that uses sheet/line number labeling

I'm designing my second system in Skycad and switched to the style where all components and wires get a page number and row number.  One concern I have is best practice when updating the design.  Lets say I need to modify a panel where this naming convention has been used, how does one update the drawings? It seems that even a simple repositioning of the component on the sheet would either require relabeling of the component or break the usefulness of such a naming strategy.  

Any guidance or best practices?

 

Thanks

Yep...

Thanks for posting on the forum.

You've pin pointed the main flaw of that specific numbering system: moving stuff around breaks the logic.

The best way to avoid that when modifying an existing set of schematics is to try to use Off-page references as much as possible and send added elements on extra pages you add at the end.  But it doesn't always fit all scenarios.

At least with SkyCAD there is a way to freeze existing labels so executing a global renumbering won't change existing tags.

That's pretty much all there is to it.  

Let us know if it is helpful, and if you need more information.

Here are my unsolicited 2 cents. It isn't really a SkyCad-specific issue, but really an industry-wide issue with that numbering system. I use that numbering system and while it drives me crazy after a machine is built and I am forced to move things and they aren't in their proper row anymore, they are usually in the same area. So the number system gets you pretty close to them and still serves its purpose.

Alain makes a good suggestion about using OPRs, if you have to make a big change that is your best bet.

Thanks for all the replies.

Thanks for all the replies. Just to clarify, I didn't mean to imply that this was a skycad specific issue. I see that this would be a challenge any time this naming convention is used.  The main questions is if there was any good approach to address the issue that may be used across the industry.

Based on the feedback above I am going to keep using this style of labeling and will develop a standard approach for documenting changes that help maintenance personnel if there are changes to a panels design after the initial build.

Thanks!
