Here's for Circle thru bpoly:

 

 

(defun c:CPoly (/ cen ent i ss)
 (vl-load-com)
   (if (setq i  -1 ss (ssget '((0 . "CIRCLE"))))
   (while (setq ent (ssname ss (setq i (1+ i))))
     (setq cen (vlax-get (vlax-ename->vla-object ent) 'center))
     (vl-cmdf "._bpoly" "_a" "_B" "_n" ent "" "" cen "")
     (entdel ent)
   )
 ) 
)

I'm trying to use the ellispe to polyline lisp but it is only convert to polyline, it is possible to convert to lwpolyline ? I'm thinking can I use this lisp convert to polyline first and then use the bpoly command convert it to lwpolyline, but after convert the ellispe to polyline, I can't get anypoint inside the polyline. Is there other method ?

 

Thanks !
