导出元件位置后怎么导不进来？

布完局后导出export-placement

然后再导进来时什么都没有，查后viewlog后有这样一个说明：

lace by Text File for #Taaaaaa03920.tmp on Thu Feb 23 10:18:15 2006

 Save as #Taaaaaa03920.tmp

 Refdes R1 has no component instance ... skipping

 Refdes R2 has no component instance ... skipping

 Refdes RN3 has no component instance ... skipping

 Refdes RN4 has no component instance ... skipping

请问怎么搞定?是不是在导出placement时还要做什么准备工作?

placement origin选的都是symble origin

封装库路径指定了吗?

同意楼上的说法.
