Saving a named object in dwg then purging it

[Ahankhah]

Hi all,

 

is it possible to:

1- Get properties of a table group (such as a layer, textstyle, dimstyle, ...)

2- Save the information inside drawing (via Dictadd, etc.)

3- Purge the processed table group.

 

So it will be possible to restore the information when needed.

 

 

If possible, any suggestion is greatly appreciated.

Try it

(defun savetable (table / d)
   ;;; table - "LAYER" "DIMSTYLE" "STYLE" "LTYPE",
