[求助]：怎么画局部放大最快，最方便？

一聊百了

我是CAD新手，请问怎么能最方便得画出一个零件的局部放大，包括标注，如果一个局部放大是圆形的，又怎么把它圈进块里？

我看了以前的好贴，就只说一张图画两个不同的比例，我只知道了一点可以用测量放大和不同的布局来实线。但这是局部放大，请高手指点，谢谢。

我真笨还是有点不太清楚。等我再试试

TRY THIS CODE:

(defun c:detail ()
  (vl-load-com)
  (setvar "osmode" 0)
  (setq ent (entsel "\nSelect Boundary:")
         p1 (cadr ent)
        ent (car ent))
  (vl-cmdf "divide" ent 60)
  (setq pg (ssget "x" '((0 . "POINT"))))
  (setq n 0)
  (while (< n (sslength pg))
    (setq en (entget (ssname pg n)))
    (setq pl (append pl (list (cdr (assoc 10 en)))))
    (setq n (1+ n))
  )
  (vl-cmdf "erase" pg "")
  (setq ss (ssget "cp" pl))
  (vl-cmdf "copy" ss "" p1 p1)
  (setq p2 (getpoint p1 "\nPut Detail at:"))
  (vl-cmdf "move" ss ent "" p1 p2)
  (setq n 0)
  (while (< n (sslength ss))
    (setq obj (vlax-ename->vla-object (ssname ss n)))
    (setq p3 (vlax-curve-getstartpoint obj))
    (setq p4 (vlax-curve-getendpoint obj))
    (if (ptinters obj (vlax-ename->vla-object ent) 2)
      (progn
        (setq pp (car (ptinters obj (vlax-ename->vla-object ent) 2)))
        (if (> (distance p2 p3)(distance p2 p4))(setq p4 p3))
        (vl-cmdf "_trim" ent "" p4 "")
      )
    )
    (setq n (1+ n))
  )
  (vl-cmdf "text" (getpoint "\nInput Detail point:")(* (getvar "dimscale") 0.18) 0 "DETAIL A" "")
  (vl-cmdf "erase" ent "")
  (setvar "osmode" 37)
  (princ)
)
