多谢进来的各位,请看看下面的程序运行后为什么不显示起点和终点坐标?
static void asdklineinfo_info(void)
{
// add your code for command asdklineinfo._info here
acgepoint3d pt1,pt2;
ads_name eline;
acdbline* pline;
acdbobjectid eid;
acdbgetobjectid(eid,eline);
acdbopenacdbentity((acdbentity*&)pline,eid,acdb::kforread);
pt1=pline->startpoint();//得到起点
pt2=pline->endpoint();//得到终点
pline->close();
acutprintf("得到了起点和终点");

}
