AutoLISP program gives different result each time

[Anonymous]

When i run a AutoLisp program, it gives me different result each time. When I call a value for a perticular variable using "!" it gives right value but when this variable is used to draw polyline, it gives me different polyline. I have defined four points named pt1, pt2, pt3 and pt4. After having offest value another 4 points are created named opt1, opt2, opt3 and opt4. When I check the value of pt1 and opt1 using !pt1 and !opt1, it gives me distinct value but when I draw a polyline using (command "pline" pt1 pt2 pt3 pt4 "c"), the result is either a triangle !! or polygon. 

someone please help.

Have you tried this with osnaps and polar tracking/ortho off?

(setq n4mosmode (getvar "osmode"));save osnapmode

(setvar "osmode" 0);turn of snaps

lisp....

(setvar "osmode" n4mosmode); reset osnap mode <---- edit n4mosmode to match.. was n3m

Sometimes osnaps etc can interfere w/ drawing geometry.

Hi,

Disable osnap *before* take points: (setvar "OSMODE" 0). Usually you need:

(setq OldOsmode (getvar "OSMODE"))

(setvar "OSMODE" 0)

...

(setvar "OSMODE" OldOsmode)
