Hello All, I have looked around a little bit and haven't been able to find the answer I am looking for. I know commands like LAYTHW AND LAYON. I also used the info from "Michael's Corner" latest post. Everything is turned on and everything is thawed. However, it does not thaw layers that are labeled as VP Freeze. Instead of going to the layer properties manager, select all, and thawing the layers that are frozen in the view port freeze, is there a way to thaw all of them with a simple command or a button that is already created or one that I can make in the CUI? As always, any and all comments are appreciated. I have a feeling ReMark, BlackBox, BIGAL may have some insight in to this, or at least point me in the right direction.

Is it possible to create a macro, and turn that macro into a keyboard shortcut that will THAW, your most recent turned off layer, or layers if multiple were frozen at the same time? This would be super helpful if somebody could help me out here! Thanks, Matt W.

Hi, I found and modify a lisp routine, I would like to know if it is on the right track. Also to mention that I don't really understand all the mechanics of it but first, here's what I want to achieve : -I have a Layer named "Arch - Niveau 1" -I would like to enter in the command prompt "a11" -It would read if the layer is frozen or thawed and if it is frozen, it will thaw it (? sorry bad english) And if the layer is thawed, it would freeze it That's it! What could be added is: To check up if the layer exists and if not, create it. Would do the same for 2 other layer named "Arch - Niveau 2" command "a22" and "Arch - Niveau 3" command "a33". Is it clear? Now the lisp I've found and modified is this: (defun c:a11 (/ lay ldef flag) (setq layn "Arch - Niveau 1") (command "_.LAYER") (if (not (tblsearch "LAYER" layn)) (command "_Make" layn) (progn (setq ldef (tblsearch "LAYER" layn) flag (cdr (assoc 70 ldef))) (and (= (logand flag 1) 1) (command "_Thaw" layn)) )) (command "") ) This lisp looks if it exists, if not, create it and only thaw the layer. I'm not sure I want to understand all the mechanics because I'm not enough familiar with the "not", the "progn" the "flag", "and" and "logand" (!!!!) Can you help me complete my lisp please? Thanks a lot !
