lisp to isolate layers using wildcards in the name...
That's a lot easier, since isolating Layers is just a function of having them On and all other Off, both of which [unlike deleting them] are achievable within the Layer command's regular options:
(setq laynames (getstring "\nEnter Layer Name(s) to isolate [wild-cards can be used]: "))
(command "_.layer" "_off" "*" "_yes" "_on" laynames "")
Or, if you will always want a group of Layer names with the same beginning, and to wild-card the rest:
(setq laybase (getstring "\nEnter start of Layer Names to isolate all that begin that way: "))
(command "_.layer" "_off" "*" "_yes" "_on" (strcat laybase "*") "")
You may also want to include something to set the current Layer to one of those that will be on, which makes it a little more complicated but is certainly doable. Or you may choose to answer "_no" to the question of whether to turn the current Layer off.

I find very useful routine to delete layers using laydel with wildcards in the name here:

my question is:
Is it possible to modify some of these programs in this topic in order to isolate layers in a same way?
I tried to solve this issue but I have a problem: Layiso command used layers picked by user and I don't know how to take these layers names as initial values
Any help will by very appreciated.
Hi Igal,
perhaps something like this:
(defun c:demo ( / laynames ss)
(if (and (setq laynames (getstring T "\nEnter Layer Name(s) to isolate 'wild-cards can be used': "))
(setq ss (ssget "_X" (list (cons 8 laynames) (cons 410 (getvar 'CTAB)))))
)
(command "_.layiso" ss "")
(prompt (strcat "\nNo objects found in layers " laynames "... "))
)
(princ)
)
Hope this helps,
Henrique

Thank you for your efforts. Routine working good!
Now i need an "emulation" of LAYUNISO function. After invoking "demo" function for example regular LAYUNISO function can not return previous position...
I think on this step need to involve layerstate-save and layerstate-restore functions..
How can I do it?
You're welcome!
'regular LAYUNISO function can not return previous position...'
???
Command: DEMO
Enter Layer Name(s) to isolate 'wild-cards can be used': _*
_.layiso
Current setting: Hide layers, Viewports=Off
Select objects on the layer(s) to be isolated or [Settings]: 1814 found
Select objects on the layer(s) to be isolated or [Settings]:
6 layers have been isolated. Layer _model is current.
Command:
Command: LAYUNISO
Layers isolated by LAYISO command have been restored.
LAYUNISO command, will restore the previous layer state...

If you use a regular-Layer-command approach [such as suggested in Post 2], then the LAYERP command will take you back to the previous condition.
