Similar to the Multi - Layiso

The isolating works great my problem now is I don't know which ones I have done and haven't done. I need to freeze the layers. Cant really turn it off because I will be using the layon command.

How about a lisp that freezes all 3 layers based on the original Road ... Road, Road - cen, and Road - edg.

 

So lemme get this straight.
a) you needed to create the add'l 2 layers by picking the 'base' layer....
check.
b) you needed to pick one of the 'base' layers, and turn on only those 3 layers,
all others off... check.
c) now you want to freeze those 3 layers.
First you'll need to either set current layer to something other than the 3
layers you'll be freexing, like perhaps 0. Then you can freeze the 3 layers,
turn everything else on, and then select your next base layer to
multi-isolate...right?

(defun c:muf () ; multi-freeze
(setq layername (getvar "clayer"))
(setq allnames (strcat layername "-cen," layername "-edg," layername))
(command "layer" "t" "0" "s" "0" "f" allnames "on" "*" "")
(princ)
)

(defun c:mui () ; multi-isolate
(princ "\nSelect layer to isolate:")
(setq layername (cdr (assoc 8 (entget (car (entsel))))))
(setq allnames (strcat layername "-cen," layername "-edg," layername))
(command "layer" "s" layername "off" "*" "n" "on" allnames "")
(princ)
)

done and haven't done. I need to freeze the layers. Cant really turn it off
because I will be using the layon command.

Road, Road - cen, and Road - edg.
