I used to have this really handy lisp but have switched companies and forgot to bring it with me.
The command was LPO and it would turn every off layer on, even xref, and I would be able to individually click the layers that I wanted to remain on. After clicking enter, the other layers would return to the off state. One of the most useful routines I have ever seen.
I have very basic knowledge of lisp around would really appreciate some help.
I also did a search and couldn't find anything similar.
Thanks in advanced.
