needa a lsp.

I have a drawing with many hatches on the same layer. I need a lsp that will allow me to select one of the hatches and send the entire layer to the back. Any ideas?

Are you referring to the drawing order of the objects?

yes, i am dealing with many areas of concrete pavement all with a hatch. I have many utilities and such that are below the walk hatch and i need to be able to send the entire layer to the back (draw order) as opposed to sending each hatch back one section at a time.

This should do the trick - will work on any entity:

(defun c:hatchback (/ lEnt lLay lSels)
 (setvar "cmdecho" 0)
 (while (setq lEnt (car (entsel "\nSelect Entity on Layer to Send to Back > ")))
     (setq lLay (cdr (assoc 8 (entget lEnt)))
       lSels (ssget "X" (list (cons 8 lLay)(if (getvar "CTAB")
                                         (cons 410 (getvar "CTAB"))
                                        (cons 67 (- 1 (getvar "TILEMODE")))))))
     (command "_.draworder" lSels "" "B"))
 (setvar "cmdecho" 1)
 (princ))
