Delete Layers Off

How Can I Delete All Layers Which Are Off?

Format > Layer Tools > Layer Delete. Use the Name option.

thanks remark, i know what you say but i have alot of layers which are off so i need delete them all without enter name of layers.

Have you tried searching for a custom Lisp program that would do this? I think that would be the easiest way to go.

Try over at CADalyst Magazine in the CAD Tips section.

Look at tip #962 by Mike Aaly.

He has a pair of routines that lets you delete all entities on layers selected within a dialog box.

Registration is free. Use the search feature with the words delete layer.

Or alternatively, you could W-Block all visible entities to a new drawing, and leave all those layers turned OFF behind.

thanks guys, Dear Remark you say (Routines that lets you delete all entities on layers selected within a dialog box) but i want delete them without selection it seems like i tell autocad for all layers off delete them

i wish you understand me now

thanks again

Without selection will require a Lisp routine. When you finish writing it you can share it with us. Thanks.

Try this one from JTB World. I just tested it and it worked for me. No selection required. layers-erase.lsp

Cad64 to the rescue. Kind of like Car 64 Where Are You.
