Block on top of hatch

[rodrigo_sjc_sp]

What is the simplest way to know if there is a block over a hatch

 

I have the following code

 

           (setq selec33 (ssget "_WP" lis_coords
           (list
                       (cons 0  "HATCH")
                       (cons 8  "H1,H2,H3")
          )
          )
          )
          (setq b 0)
          (if (not (equal  selec33 nil))
          (progn
               (repeat (sslength selec33) 
               (setq entblk33 (ssname selec33 b))     
               (setq lis_ent33x (entget entblk33))     
               (setq nomeblk33 (cdr(assoc 8 (entget entblk33))))
               (setq valor_hatch (vla-get-area (vlax-ename->vla-object entblk33)))

..................
           (So far the code works, I got the hatch) 
..................
           (NEW!   I need to check if there is a block on this hatch , the block name is TESTER. If it is over this hatch sending an alert and continue code) 
..................
                (setq b (+ b 1))
   )
  ))

Try this, for hatch boundaries containing segments only.

 

    (setq EL (entlast))            
   (vl-cmdf "_-hatchedit" entblk33 "_B" "_P" "_N")
   (if (/= EL (entlast) (setq bnd (entlast)))
       (progn
           (mapcar
               '(lambda (x)
                    (if (eq (car x) 10)
                        (setq Lv (cons (list (cadr x) (caddr x)) Lv))
                    )
                )
               (entget bnd)
           )
           (entdel bnd)
           (if
               (or
                   (ssget "_F" Lv (list '(0 . "INSERT")(cons 2 "TESTER")))
                   (ssget "_WP" Lv (list '(0 . "INSERT")(cons 2 "TESTER")))
               )
               (alert "The block TESTER is on the hatch.")
           )
       )
   )
