Layer Deletion

[jnicholsDAEW5]

In this file I am unable to delete 16 unused layers that I don't want in the layer properties. I would like to delete everything after "11 ANNOTATIONS - DIMENSION".

Pure the blocks then purge the layer. If it can't purge, then use LAYDEL

The message says the layers still have content on them. If you think otherwise, then merge those layers you no longer want with layer 0 and see what shows up on that layer if anything does (and they will be gone forever to boot).

Is there a way to identify the objects on the layers that I want to delete?

I'm thinking if I could select all the objects on the layers I want to delete I could then move them all at once. Hopefully I would move nothing because the layers are empty (I thought), but if I notice something move I can just delete it then

@jnicholsDAEW5 If using LAYWALK through them to find out what you need is not enough then you'll probably need to ask in the LISP forum for a way to drill down into block content etc. to find out more https://forums.autodesk.com/t5/autocad-customization/ct-p/AutoCADTopic1

Hi,

>>"Is there a way to identify the objects on the layers that I want to delete?"

see Patchys answer, he used command LAYDEL to see if a layer is used inside a block,

for a test it is okay and a good help  (don't save, undo this step).

Just the hint to use laydel if you can't purge a layer isn't a really good hint (in my eyes),

LAYMRG to 0 is the way to go.

But laydel and laymrg is just good to find layers in blocks,

newer software products can use PURGE command to find much more,

for example Attributes which refer to a layer.

Purge, switch to the second view (unpurgeable objects), select the item you want to purge and

read the information listed below.

This was EXTREMELY useful. The second tab helped me identify what and why it was not deleting. THANKS A TON
