Question
Hello, I'm looking for a lisp routine that will allow me to choose a layer that I would like to thaw by selecting an entity on that layer.  I imagine that it would have to temporarily thaw all layers and retain the label of the layer that I pick, then "refreeze" all of the layers that were frozen prior to calling up the lisp routine, except for of course the layer that I chose. Any help would be great, thank you very much!

Answer
That's a little different than what is available out there now. It certainly could be written. It's close to a routine called isolate -
if you want to end up with that one layer only on. The manual step would be you'd have to thaw/on everything, remembering current states first.
Usually the 'best practice' is to use freeze/thaw for permanently off stuff, and on/off for temporary visibility changes. There are plenty of routines like that available on the net.
