Layers that won't purge?          
Sometimes while using AutoCAD, you want to delete a layer, but even
after removing all entities from the layer in question, it will not
purge. Hopefully the following troubleshooting will help.


Causes
There are really only two causes. An entity is referencing the
layer you are trying to delete, or it's a corrupt drawing. Look for
entities in these places:


  • Block definitions

  • Empty text strings

  • Viewports with frozen layers



Solutions
Depending on the version of AutoCAD and 3rd party applications
that you have:

  • If you have Express Tools, use the Layer Merge command to merge entities from the mystery layer onto layer 0 (zero).

  • Go to http://www.manusoft.com
    and take a look at SuperPurge. This tool will delete any referenced item using it's hard purge method. This low cost tool is well worth it's price.

  • Find the entities that are referencing the layer you wish to
    delete and delete those entities, or move them to another layer.

    • Use BEDIT or REFEDIT to check your block definitions.
    • Turn on QTEXTMODE in order to see empty text strings.
    • If you have viewports, switch to each and make sure the layer isn't frozen.



If none of these work, you may have a corrupt drawing. Try using WBLOCK to create a new drawing.

Hi R.K., May I suggest informing users that when Wblocking that they do not use a crossing window (right to left) nor do they answer the prompt with "all". Both of these could include the offending entities in the new dwg. Always window from left to right and/or directly pick the entity(ies).
