PADS 2007 中网络标号与铺铜问题

请问：
问题1：用LOGIC画原理图除了用off-page连接网络外，还可以怎么填加网络标号？而且使用off-page经常出现以下的警告呢，好多啊，怎么解决啊？
Line 36 , Section *DEL_ATTRIBUTE*
"Comment"
* WARNING: Processing command to delete attribute "Comment" from Component J11.
* The attribute is also inherited from Decal 302S-60P.
* The change is not fully reconciled for cases where the schematic
* does not support hierarchical attributes.
Line 38 , Section *DEL_ATTRIBUTE*
"Comment"
* WARNING: Processing command to delete attribute "Comment" from Component L1.
* The attribute is also inherited from Decal L-9UH/1A(3.5).
* The change is not fully reconciled for cases where the schematic
* does not support hierarchical attributes.
问题2：在pcb中，某些元器件的某个脚与大面积铜连接（类似于原理图中的总线），该怎么实现呢，是使用copper 还是copperpour?又或者其他的。
谢谢！

怎么都没有人帮忙回答啊

2,用copper pour比较好，可以自动避让不同网络与规则。
