Wipeout Lisp That helps me avoid the manual typing.

I was doing alot of wipeout and was not enjoying the typing to create them when i wanted to select the same things each time.

I wrote this lisp to help me speed the process up.

It is very simple and is great for showing how you can use lisp to create short cuts for autocad comands.

I would love the recive comment/critesim for this lisp and anything to help be better understand lisp.

;wipeout shotcut
(defun c:wp()
 (setq pl1
 (entsel "\nSelect closed polyline to convert to wipeout:")
);setq
(command "wipeout" "polyline" pl1 "yes")
 (command "change" "last" "" "properties" "color" "green" "")
);defun

one of this issue i had with is lisp is the command function. If you want an ENTER you have to "" not " ".

It is better to check if the selected entity reach our requirements and after that we can implement the action on it.

Check is out ....

(defun c:wp (/ pl1)
 (if (and (setq
            pl1 (entsel "\nSelect closed polyline to convert to wipeout:")
          )
          (vlax-curve-Isclosed (car pl1))
     )
   (progn
     (command "_.wipeout" "_polyline" pl1 "yes")
     (command "_.change" "last" "" "properties" "color" "green" "")
   )
   (princ)
 )
 (princ)
)

Why not use a background mask on mtext instead of using a wipeout?

Why not use a background mask on mtext instead of using a wipeout?

Good point Dink .

That's what came to my mind but there is a small problem with it is that when the entity is mtext and its width is wilder than its characters , the background going

to follow the width of the mtext and not the width of all chars in a text .

Sunny & Tharwat's lisp no effect with cirlce or pline ( line + arc ). you can combine with my lisp ( for circle ) & develope more... Good luck

(Defun c:WC ()
(command "undo" "be")
(setq luubatdiem (getvar "osmode"))
(setvar "osmode" 0)

(Princ "\nHay chon CIRCLE :")
(setq XX (ssget '((0 . "CIRCLE"))))

(setq L 0)
(setq M (sslength XX))
(while (< L M)
(setq DT (ssname XX L))
(setq DT (entget DT))
(setq TAM (cdr (assoc 10 DT)))
(setq BANKINH (cdr (assoc 40 DT)))

(command ".polygon" "30" TAM "" BANKINH) 
(command ".wipeout" "" "last" "y") 

(setq L (1+ L))
)

(setvar "osmode" luubatdiem)
(command "undo" "end")
(Princ)
) 

Sunny & Tharwat's lisp no effect with cirlce or pline .....

(Defun c:WC ()

Really ????

By the way , cool name for the routine .

Why not use a background mask on mtext instead of using a wipeout?

Yes i always use a background mask for text it is just a whole lot simpler.

But i used the wipeout for other things like Blocking out the road under a Bridge

Sunny & Tharwat's lisp no effect with cirlce or pline

Just to clarify Tharwat's and mine only work on closed pline.

Hi again i just was using the lisp and decided that i could improve it to make it more user friendly.

if you select a ployline that is not closed, (as these can not become wipeouts). it will display an error message.

Is there a way you can make this come up next to the mouse if you have dianmic imput on?

Thanks you guy are awsome as ussual.

(defun c:wp (/ pl1)
 (if (and (setq
            pl1 (entsel "\nSelect closed polyline to convert to wipeout:")
          )
          (vlax-curve-Isclosed (car pl1))
     );and
   (progn
     (command "_.wipeout" "_polyline" pl1 "yes")
     (command "_.change" "last" "" "properties" "color" "green" "")
   );progn
   (prompt "\nERROR ployline not closed!")
 );if
 (princ)
);defun

So ive used prompt in this one but it is not distinctive enother to tell me theres an error

the display says

ERROR not closed ployline

Command:

and how would i get it to display on the bottom line i.e. where "command:" is

i would like this becasue it is make is more easy see

Thank you for the code, I've changed and added one line to this to suit my needs.

(command "_.wipeout" "_polyline" pl1 "yes")

(command "_.change" "last" "" "properties" "color" "T" "255,255,255" "")

(command "DRAWORDER" "last" "" "back" "")

Basically the color is now 255,255,255. Just means the wipeout line will appear not to print.

Draworder to send it to back. I used it mostly inside blocks but this is generally how it works best.
