bug in program? bug in acad?

I make MANY simple drawings, take a screenshot, then paste in ms paint

In order for my many screenshots to have the same scale, I put a handle point in the upper right and lower left corners. I zoom window and snap to these handle points.

The program works great if the handle points are lines (snap endpoint or intersection)

However, if the handle points are circles, (snap cen) nothing happens

If I do the same thing without the macro, snap cen works great

I'm almost certain circles for handle points worked before. Now nothing

(defun c:zw ()
   (setq pt1 (getpoint "\nSelect First Window Point: "))
   (setq pt1 (osnap pt1 "_endp"))
   (setq pt2 (getpoint "\nSelect Second Window Point: "))
   (setq pt2 (osnap pt2 "_endp"))
     (command "zoom"
     "w"
   pt1
   pt2
     ) ; end zoom
    (princ)
) ; end programIts not ideal though.

Is not a bug, it is because circles don’t have EndPoint Osnap – you should modify the filter to accept CenterPoint too:

(osnap pt1 "_end[color=red],_cen[/color]")

Regards,

Try this one ....... it is dedicated to you.

(defun c:zw (/ old  pt1 pt2)
(setq old (getvar 'osmode))
 (setvar 'osmode 1)
 (setq pt1 (getpoint "\nSelect First Window Point: "))
   (setq pt2 (getpoint "\nSelect Second Window Point: "))
   (command "_.zoom" "_w"  pt1 pt2 )
 (setvar 'osmode old)
    (princ)
)
