[求助]关于pause的使用

05625lcc

为什么下面的程序

(
  defun c:cf(/ c_chamfer)
  (setvar "trimmode" 1)
  (setvar "chammode" 0)
  (command "chamfer" "d" pause "")
  (princ)
)

 运行后结果是

Command: cf
chamfer
(TRIM mode) Current chamfer Dist1 = 5.000, Dist2 = 5.000
Select first line or [uNdo/Polyline/Distance/Angle/Trim/Method/mUltiple]: d
Specify first chamfer distance <5.000>: 2
Specify second chamfer distance <2.000>:
Command:

就这样结束了,没有出现要求选择边这些,按命令的执行应该出现的啊.而我写成下面那样反而行了

(
  defun c:cf(/ c_chamfer)
  (setvar "trimmode" 1)
  (setvar "chammode" 0)
  (command "chamfer" "d" pause "" "chamfer" "u")

;此处加了"chamfer" "u",相当于再执行一次命令,利用上次命令的两个chamfera与chamferb来进行倒角
  (princ)
)

如果pause只是暂停供用户交互的话,那么没理由第一个程序就那样结束了啊.
