Confusion with lambda function

Hi Guys

How to Create Line for coordinates from list using lambda function

Please need help for solve this

(defun c:test(/ lst )
     (setq lst '((1515.32 999.613 0.0) (2314.23 1081.97 0.0) (1690.57 752.536 0.0)
	  (2458.55 829.747 0.0) (1685.41 474.574 0.0) (2716.26 443.689 0.0))
     )
     (mapcar (function (lambda (x y)
		     [color="red"] (command "line" x y "")[/color] ????
		))
      lst
     )
)

(mapcar 
 '(lambda (x y) (entmakex (list (cons 0 "LINE") (cons 10 x) (cons 11 y))))
 lst
 (append (cdr lst) (list (last lst)))
)

Or:

(mapcar 
 '(lambda (x) (entmakex (list (cons 0 "LINE") (cons 10 (car x)) (cons 11 (cadr x)))))
 (mapcar 'list lst (append (cdr lst) (list (last lst))))
)

EDIT: Or if you use LM's entmake functions, then you could just

(defun LWPoly (lst cls) ; LM
 (entmakex 
   (append 
     (list 
       (cons 0 "LWPOLYLINE") (cons 100 "AcDbEntity") 
       (cons 100 "AcDbPolyline") (cons 90 (length lst)) (cons 70 cls)
     )
     (mapcar (function (lambda (p) (cons 10 p))) lst)
   )
 )
)

do this:

(LWPoly lst 0)

Grrr

That was awesome and i don't want to create only 3 Line Entity's for example '(1 1) '(2 2) '(3 3) Please waiting for your reply

If you want to create lines from a point list, you have to group the items so each one consists of 2 points (a line is defined of 2 points) :

Instead of such list

'(1 1) '(2 2) '(3 3)

you'll have to use:

(list
 '((1 1) (2 2)) ; line #1
 '((2 2) (3 3)) ; line #2
 '((3 3) (1 1)) ; line #3 (if you want to close the shape)
)

Grrr thank you It is helped me lot
