Autocad 2009 routine for LAYUNISO

[eoconnor95662]

This is my code:

 (defun c:test ()
 (command ".layer" "thaw" "*" "")

(princ)

)

It returns NIL. Is there something wrong with that tiny bit of code? It doesn't do anything when used other than return NIL.

Feedback appreciated. Thank you!

It works fine here in 2019

Impossible, please load it again and try it again.

Copy & Paste to your commandline, it should also work in 2009

Perhaps your Layer are OFF and not freezed, or both?

(defun c:test ()
(command "_.layer" "_thaw" "*" "_on" "*" "")
(princ)
)

What it looks like it is doing is it correctly turns the freeze layer on even when returning NIL but the layer doesn't show up on the CAD drawing. I was testing this by using a combination of layiso and layfrz.

The objective is to have it turn back on layiso layers and not turn on previously turned off layers.

I don't have an answer, nor do I understand what the Thawing in Message 1 has to do with the thread Title.  But maybe you can use a routine I did that improves on certain aspects of LAYISO/LAYUNISO, called LayerIsolateOnOff.lsp available >here<.  See the description there and comments in the file for how the commands defined in it differ from AutoCAD's version.  There's also >another one< that does the same using Freeze and Thaw instead of Off and On, called [logically enough] LayerIsolateFreezeThaw.lsp.

>here< is exactly what I was looking for. Thanks Kent!
