HOW TO REMOVE OLD LINE NUMBER

[Mdelaney_Jr]

When creating an ISO from the model I use the pipe routing that allows you to assign a line identifier. The problem I have is if I no longer need that pipeline I can remove the identifier from the layer drop-down but not the dropdown list that is created in the pipe routing element. Can someone show me how to purge these line numbers out once I have deleted the line itself?  (See Pic)

Have you tried AUDITPROJECT from the project manager?

Thanks, I tried Audit, PLantaudit, and auditproject and they are still attached to the file.

Have you tried the PnPLocalDataCachePurger.exe ?

You can find it here: C:\Program Files\Autodesk\AutoCAD 20xx\PLNT3D
Make sure to close Plant 3D before running it.

Thanks, I will work on this and get back to you if it worked or not.

Try Using

auditproject and compressproject

I've tried all, and the line is still showing. Can someone use the Route Pipe Function by assigning a line number, size, and spec to a line, then delete the line, purge the line info (PU), then see if you still see the line in the Route Pipe dropdown. See pic @Ray_K @Michiel.Valcke @DACOMA3

If the purge is not helping then I suppose there must still be objects left in your drawing that have the old line numbers. Most likely they'll be fasteners that weren't selected when changing the line numbers the first time.

You can use the datamanager to find them.
