Restore layers Visibility after layiso command - LayerState??

[andre81]

Hi All,

 

I'm Autolisp beginer and first problem which I would like to solve with it is how to restore layers Visibility after Layiso command.

 

In few steps it's looks like:

 

1. Before use Layiso command I'have some layers that are on others are off.

2. I'm using Layiso and makes some changes on drawning.

3. After changing I want to restor layers visibility from point 1 (before Laiso command).

 

My idea is to use LayerState functions: layerstate-save, layerstate-delete and layerstate-restore. I have problem with using LayerState functions.

 

 

I could name functions for example "Iso" and "RestoreState".

LayerState name could be "XX"

 

Program structure:

 

Step 1 - c:Iso

I'm checking if "XX" exist.

If "XX" exist then using layerstate-delete I'm deleting "XX".

I'm creating LayerState "XX" using layerstate-save.

 

Step 2

(command "Layiso")

 

Step 3

I'm doing some changes in drawing.

 

Step 4 - c:RestoreState

I'm restoring "XX" using layerstate-restore.

 

My problem is that I don't know how to use LayerState functions.

 

Many info I've found here:

http://www.cadtutor.net/forum/showthread.php?39986-LayerState-Manipulation-Info.-Coding

but still don't know how to for example make Layerstate "XX" using it.

 

(layerstate-save XX)

or

(layerstate-save "XX")

don't work. How it should look like?

 

 

Also I've tried to use only commands:

 

(defun c:iso ()

(command "-layer" "state" "save" "XX" "" "" "" "LAYISO"))

(defun c:RestoreState ()

(command "-layer" "state" "restore" "XX" "" ""))

 

 

This code don't has checking if "XX" exist but works.

How to write code using LayerState functions??

Anyone can help?
