调用acedCommandS后读取系统变量LastPoint问题

xgr

调用acedCommandS后读取系统变量LastPoint坐标确是调用命令前的值

1. int nRet = acedCommandS(RTSTR, _T("_copy"), RTPICKS, ss, RTSTR,_T(""),RTPOINT, basePt, RTSTR, PAUSE, RTNONE);
   
2.     struct resbuf rb;
   
3.     AcGePoint3d lastPoint;
   
4.     acedGetVar(_T("LastPoint"), &rb);
   
5.     lastPoint[X] = rb.resval.rpoint[X];
   
6.     lastPoint[Y] = rb.resval.rpoint[Y];
   
7.     lastPoint[Z] = rb.resval.rpoint[Z];
   
8.     acutPrintf(_T("\n最后点坐标：X=%0.3f,Y=%0.3f,Z=%0.3f"), lastPoint[X], lastPoint[Y], lastPoint[Z]);

int nRet = acedCommandS(RTSTR, _T("_copy"), RTPICKS, ss, RTSTR,_T(""),RTPOINT, basePt, RTSTR, PAUSE, RTNONE);<br />     struct resbuf rb;<br />     AcGePoint3d lastPoint;<br />     acedGetVar(_T("LastPoint"), &rb);<br />     lastPoint[X] = rb.resval.rpoint[X];<br />     lastPoint[Y] = rb.resval.rpoint[Y];<br />     lastPoint[Z] = rb.resval.rpoint[Z];<br />     acutPrintf(_T("\n最后点坐标：X=%0.3f,Y=%0.3f,Z=%0.3f"), lastPoint[X], lastPoint[Y], lastPoint[Z]);

而lisp则是正确的

1. (Setq Ss (Ssget "Cp" Px))
   
2.   (Vl-Cmdf "Copy" Ss "" Dp Pause)
   
3.   (Setq Dp1 (Getvar "Lastpoint"))

(Setq Ss (Ssget "Cp" Px))<br />   (Vl-Cmdf "Copy" Ss "" Dp Pause)<br />   (Setq Dp1 (Getvar "Lastpoint"))

这个不知道为什么会这样。请教大家，谢谢！

这个copy命令PAUSE后的坐标值如何获取。
