Question About Changing Multiple Tags

[doctor.ake27]

Hi, I want to change the tag for some equipment (VAVs). They are currently all tagged, but the naming was done incorrectly. Is there a way I can quickly change all the VAV tags? Each VAV name is not the same so I can't use "find & replace" command. Any suggestions on how to streamline this process would be appreciated. I don't want to change each tag individually. Thanks for any help. 

For example I want to change the tag "A1-VAV-01" to "VAV-01-AC-1",  "A1-VAV-02" to "VAV-02-AC-1", etc.

Probably export the parameters to an external file, sort and edit them in there and re-import them? 

DBlink or DiRoots Sheetlink or similar could help with that.

Or you could use DiRoots Reordering or similar.

Without a uniform format though how will any type of software know how you would want to rename the items - I think a certain amount of manual effort will be unavoidable.

You don't change the tag, you change the parameter in the family that is tagged. the tag just reads and displays the value of the parameter (it is dumb, which in this case makes it smart).

I assume the "mark" parameter is what you use. 

Unless we talk about millions of VAV, you could manually change the parameter in the schedule. That would be easier than to hunt all of them in different views and it would be obvious which ones aren't changed yet.

You can change the tag and that will also change the parameter - tags are not dumb, they display exactly the same data as a schedule or the properties pallete and are fully interactive.

Using a schedule is however a better way or, as I described, export to a spreadsheet or data base to make use of the sorting and auto-fill capabailities and then re-import.

Using DiRoots re-ordering tool you can also do it semi-automated graphically by selecting the order in which you want to number the items and using a predefined prefix and suffix which might better suit @doctor.ake27 's numbering method.

So there are several different methods available.
