it looks simple question but very strange

hi freinds

may be some one think this is very simple question but please check

if i creat polyline using this lisp shifting ucs to 3point and sequence of points of ucs is clockwise the polyline generated can't be joined to any other

but if select the 3 point anticlockwise the polyline generated can be joined to other

(defun c:pc(/)
 (setq st1(getpoint"\n p0"))
 (setq pc(getpoint"\n p(x-direction)"))
 (setq ps(getpoint"\n py(y-direction)"))
 (setq ptlst'((0 0)(4 3)( 20 5)(33.2 10)(40.33 17)))
 (command "ucs" "New" "3p" st1 pc ps )
 (setvar"osmode"0)
(command "__.pline")
(setvar"osmode"0)
 (mapcar 'command ptlst)
 (command)
 (command "ucs" "world" )
)

although if we draw polyline manualy selecting new ucs-3points we will get same results according to direction of selecting 3points of ucs

wish any one has information about this problem to help
