Using ACADE 2006 but had same problem with 2005, not with 2004, and on the same drawings:
I use Section Codes to separate portions of a project.
Using a Component Tag format %A-%N$F and a Wire Number and Cross-Reference format %A-%N I get intermittent results sometimes showing the Section Code (%A) and sometimes dropping it off.
Usually, if it works at all, upon installing a new component or wire the Section Code will show, for example: MC-1002CR, for a Tag and for a new wire number: MC-1004.
BUT, it does not always work and especially when I do a "Component Retag" or "Wire Number Update", the Section Code drops off and the Tag will be labeled -1002CR and the Wire Number will become -1004. Sometimes the Component Tag will come back with another dash in front of it like
-MC-1024CR which is not right either.
Please see attached document for more details.
Thank you for any help offered!
