non-printing object

I want to create one non-printing object - not all objects in a layer ... how?

Set the dxf 60 to 1 then print after that reset the value to 0 to show back the previous selected objects .

Search the forum and you should find at least two threads as far as I can remember .

A work around will be to store a "no-plot" flag into entities as extended data and redefine the PLOT command to temporary move all entities bearing it into a no-plot layer, proceed to plot and move them back to their original layer.

Is not about visibility... but i think is impossible other way...

If you hide it, will not be printed either, so Tharwat is correct.

Really ?

How far are you sure ?

I'm not sure... I will be happy to be wrong...

Try this and let me know who's wrong .

(defun c:hideobjs (/ ss i sn)
 ;;    Tharwat 30.July.2014        ;;
 ;;    Hide objects temporary        ;;
 (princ "\n Select objects to hide ")
 (if (setq i  -1
           ss (ssget "_:L")
     )
   (while (setq sn (ssname ss (setq i (1+ i))))
     (entmod (append (entget sn) (list (cons 60 1))))
   )
 )
 (princ)
)
;;                            ;;
(defun c:showobjs (/ ss i sn)
 ;;    Tharwat 30.July.2014        ;;
 ;;    Show hidden objects         ;;
 (if (setq i  -1
           ss (ssget "_X" '((60 . 1)))
     )
   (while (setq sn (ssname ss (setq i (1+ i))))
     (entmod (append (entget sn) (list (cons 60 0))))
   )
 )
 (princ)
)

Your lisp is perfect! Sorry for my english, but this is not what i want ... i was thinking about setting an object to be non-printable but still visible... and THIS I think is impossible...

So you should take Mircea's Advise .

Convert plotstyles to .stb, set one style to color 255,255,254 and apply it to each object you don't want to be plotted.
