Turn off layers previously on

[notview]

Is there a way to turn off the layers previously on?

 

 

E.g., I have layer1, layer2, layer3, and so on. I turned off layer2, after doing something.. I decided to turn it on again.

 

 

Any guys can help?

There is multiple ways to achieve what you want a few, obvious layer manager LA, use the option in the layers toolbar, set up filters in the layer manager, use a lisp, use a macro LA on layer1 I am sure others will make more suggestions

Thank you Bigal, I want lisp, this will be helpful in my work if anyone can make.

I would instead isolate layers 1 & 3 (or whatever layers you want to work on), do whatever you need to do, then unisolate and layer 2 will return.

 

Layiso & layuniso are the commands I think [i usually just use the buttons on the 'Layers 2' toolbar]

[BIGAL]

If not Organic answer, so you want pick 1 or a few layers turn off then later on turn these back on is that correct ? This can be done by making a global list turn off, the 2nd lisp turn them back on. If this is what you want welcome.

(defun C:layoff ( / lay layname)
(while (setq lay (entget (car (entsel))))
(setq layname (assoc 8 lay))
(command "-la" "off" layname "")
(setq AHlaylist (cons laylist layname))
)
)

; layback turn layers back on
(defun c:layon ( )
(foreach layon AHlaylist 
(command "-la" "On" layon "")
)
)

Thanx Organic, Layiso and Layuniso is applicable if doing up to 3 layers, but more than that I think is not good.

 

 

Something like that Bigal, but allow me to make some additional explanation, I only want to be turned on is the last layer I turned off, then Esc to end, otherwise, hitting the Enter/Space for second time will be make turned on all the layers off.

Is this possible?

Kind help will be much appreciated.

I am sorry if I do not understand the question, but why not use the _layerp?

VVA, this is what I need, haha!

Thank you VVA!!

 

Layerp, it is already a command in my Cad.. (otherwise question above) is using layer on, then that's the time will be on all the layer off. but, anybody can make it in one command, that's very good!!

Just a couple of observations....

 

... Layiso and Layuniso is applicable if doing up to 3 layers, but more than that I think is not good.

 

I'm not sure where you learned this, but this limitation is not described in the documentation, nor has the LAY*ISO Commands ever failed when selecting 4 or more layers in my experience.

You may find the LAYWALK Command to be of use as well.
