为什么图形只能显示部分节点编号？
图形是板四周约束，我用节点显示时，约束边界和节点只能部分显示，如图：命令流如下：
/PREP7
LENGTH=4
YOUNG=200000
THICKNESS=0.01
!DENSITY=9.0E-6
cgxh=14
/PREP7
*IF,cgxh,EQ,10,THEN
cgh=100E-3
cgb=48E-3
cgd=5.3E-3
*ELSEIF,cgxh,EQ,12
cgh=120E-3
cgb=53E-3
cgd=5.5E-3
*ELSEIF,cgxh,EQ,14
cgh=140E-3
cgb=60E-3
cgd=8E-3
*ELSEIF,cgxh,EQ,16
cgh=160E-3
cgb=65E-3
cgd=8.5E-3
*ELSEIF,cgxh,EQ,18
cgh=180E-3
cgb=70E-3
cgd=9E-3
*ENDIF

D,ALL,ALL
ASEL,S,AREA,,1,1
/PNUM,NODE,1 !显示节点编号
/REPLOT
NPLOT ！以节点显示 NSEL,S,LOC,Y,LENGTH,LENGTH
显示的只是上个命令选中的节点，用NSEL,ALL后再显示。 NSEL,S,LOC,Y,0,0
这种命令以前，使用allsel,all 谢谢！
