原创 AltiumDesigner 错误-网络不匹配

小弟在同一个Project下建立了数个Sch文件，各文件间是平行关系，并非垂直关系，Net Identifier scop是global，编译未发生错误。

但是在转Pcb时，出现一个从未见过的窗口

  然后点击OK，出现以下窗口

 然后小弟就不知所措了……

请问这个问题的原因在哪里？应该怎么调整？应该参阅那些帮助文档？

另外，小弟的Sch里并没有C17这个Designator，那上图里NetC17_2是哪里来得？

解决办法:
The message shows you the difference between PCB and SCH.
The ”unmatched Reference Objects” column is the nets list from SCH. The “unmatched Target Objects” column is the nets list from PCB.
I believe you already have a PCB file in your project. The nets in PCB file (e.g. netC17_2,.. exist in PCB) are not appear in SCH.
If you have no idea what the nets and components are, open the PCB file and find them out, then you can match the nets manually. You can also click “NO” in the first message window, the software will match the nets for you automatically.
Another way (simple, but only for first time PCB update) is remove the PCB file from the project, create a new PCB and add it into the project.
I found the Protel help is helpless (sorry Altium), you can try to type the key words in search tab
