求助 关于DXP 设计规则检查

DXP中用DRC来验证PCB的设计，.DRC文件出现如下字样，请高手指点

Processing Rule : Room SAD (Bounding Region = (151.257mm, 75.057mm, 768.604mm, 115.062mm(InComponentClass('SAD'))
   Violation between Component X101(20.193mm,32.639mm) on Top Layer and
                     Room SAD (Bounding Region = (151.257mm, 75.057mm, 768.604mm, 115.062mm) (InComponentClass  ('SAD'))
   Violation between SOIC Component U3(78.232mm,46.736mm) on Top Layer and
                     Room SAD (Bounding Region = (151.257mm, 75.057mm, 768.604mm, 115.062mm) (InComponentClass('SAD'))

请问高手上面这段文字表示我的PCB中有什么错误，如何修改，谢谢！具体是这样的，我把SCH  Update 到PCB中 ，然后我在SCH中改了一个元件，然后Update更新PCB ，DRC检查后就出现上面的错误，请问是为什么 怎么改?谢谢

 我都想知道！

就是你的X101和U3不在你导入时的那个框(SAD)里
