Turning on and freezing 1

[Melko]

I am just curious...
What is the difference between the two possibilities?

A part the fact you can not freeze but you can turn off the current layer, of course....

When a layer is turned off it is still redrawn at each regen.
When it is frozen it isn't. Can help performance in large drawings.

Assumption:
A block is created using layers CAT, DOG, and PUDDING and is inserted on current layer PEANUTBUTTER.

Results:
If you turn OFF PEANUTBUTTER, the block is still visible

If you turn OFF or FREEZE CAT, the remaining elements are still visible (The same is true for DOG and PUDDING)

If you FREEZE PEANUTBUTTER, the block disappears regardless of the settings for layers CAT, DOG, or PUDDING.

Just to follow up. I freeze those layers I don't ever (or rarely) need to see. Such as dim text or title block layer from xrefs or point numbers from survey shots, or piping line material attributes. Then as I edit the drawing I will turn on and off the layers I need to see what I'm doing clearly. When done, a simple "LO" gets the ones I want see back on.

Just fer fun:


(defun C:LO ()
(command "-layer" "on" "*" "&quot)

(defun C:LF ()
(command "-ayer" "off" "*" "&quot);;leaves current layer on

(defun c:LFX () (command "-layer" "off" "*|*" "&quot)

(defun c:LOX () (command "-layer" "on" "*|*" "&quot)

(defun c:LOXx () (command "-layer" "on" "~*|*" "&quot)
