怎样融合这两个lisp命令为一个？使用交点打断时，自动先打断多段线。即交点打断包含多段线。
1.多段线打断：
;;;选择的pline线在端点处全部断开.

;;; Purpose: Break All selected objects
;;;    permitted objects are lines, lwplines, plines, splines,
;;;    ellipse, circles & arcs
;;;                           
;;;  Function  c:BreakAll -      Break all objects selected
;;;  Function  c:BreakwObjects - Break many objects with a single object
;;;  Function  c:BreakObject -   Break a single object with many objects
;;;  Function  c:BreakWith -     Break selected objects with other selected objects
;;;  Function  c:BreakTouching - Break objects touching the single Break object
;;;  Function  c:BreakSelected - Break selected objects with any  objects that touch it

;;;    onlockedlayer   
;;;    get_interpts Return a list of intersect points
;;;    break_obj  Break entity at break points in list
;;; Requirements: objects must have the same z-value
;;; Restrictions: Does not Break objects on locked layers
