    Default Multiple circle array

    Registered forum members do not see this ad.


    I have a drawing with lots of circles (all different sizes). I need to shrink all the circles by .1mm.

    I need an 'ugway' to help my autocad kung fu.

    Here is a method

    (defun c:test ( / ss x)
    (setq ss (ssget  (list (cons 0 "Circle")) ))
    (setq len (sslength ss))
    (setq x -1)
    (Repeat len (setq obj (vlax-ename->vla-object (ssname ss (setq x (+ x 1)))))
    (setq dia (- (vla-get-diameter obj) 0.1))
    (vla-put-diameter obj dia)
