警告1，

Track (4337.164mil,2658.78mil)(4337.164mil,2895mil) Top Overlay	Pad S3-2(4337.164mil,2895mil) Multi-Layer
Track (4540mil,3175mil)(4540mil,3411.22mil) Top Overlay	Pad S2-4(4540mil,3430.904mil) Multi-Layer
Track (4717.164mil,3175mil)(4717.164mil,3411.22mil) Top Overlay	Pad S2-3(4717.164mil,3430.904mil) Multi-Layer
Track (4540mil,3175mil)(4540mil,3411.22mil) Top Overlay	Pad S2-1(4540mil,3175mil) Multi-Layer
Track (4717.164mil,3175mil)(4717.164mil,3411.22mil) Top Overlay	Pad S2-2(4717.164mil,3175mil) Multi-Layer
Track (4340mil,3475mil)(4340mil,3711.22mil) Top Overlay	Pad S1-4(4340mil,3730.904mil) Multi-Layer
Track (4162.836mil,3475mil)(4162.836mil,3711.22mil) Top Overlay	Pad S1-3(4162.836mil,3730.904mil) Multi-Layer
Track (4340mil,3475mil)(4340mil,3711.22mil) Top Overlay	Pad S1-1(4340mil,3475mil) Multi-Layer
Track (4162.836mil,3475mil)(4162.836mil,3711.22mil) Top Overlay	Pad S1-2(4162.836mil,3475mil) Multi-Layer
Track (4000mil,3215mil)(4000mil,3451.22mil) Top Overlay	Pad S4-4(4000mil,3470.904mil) Multi-Layer

问题1：

Pad Y1-1(4261.26mil,2103.308mil) Top Layer

Arc (4261.26mil,2033.307mil) Top Overlay

这个警告什么意思，我的理解是顶层的 Pad Y1-1 到一个地方的距离不合适，那么 Arc (4261.26mil,2033.307mil) Top Overlay 这句话什么意思
但是我的Y1 周围没啥东西呀既然是个距离是哪个距离？

问题2

Track (4160mil,2658.78mil)(4160mil,2895mil) Top Overlay

Pad S3-4(4160mil,2639.096mil) Multi-Layer

这句警告又是什么意思，

警告2，
Minimum Solder Mask Sliver (Gap=5mil) (All),(All)

Pad U1-18(3587.952mil,2237.52mil) Top Layer	Pad U1-17(3607.638mil,2237.52mil) Top Layer
Pad U1-19(3568.268mil,2237.52mil) Top Layer	Pad U1-18(3587.952mil,2237.52mil) Top Layer
Pad U1-20(3548.582mil,2237.52mil) Top Layer	Pad U1-19(3568.268mil,2237.52mil) Top Layer
Pad U1-21(3528.898mil,2237.52mil) Top Layer	Pad U1-20(3548.582mil,2237.52mil) Top Layer
Pad U1-22(3509.212mil,2237.52mil) Top Layer	Pad U1-21(3528.898mil,2237.52mil) Top Layer

问题3
这个警告怎么理解？

警告3

Un-Routed Net Constraint: Net V3.3 Between Pad R10-2 (2450,2060mil) And Pad R13-2 (2450,2200mil)

Un-Routed Net Constraint: Net V3.3 Between Pad U1-63 (3587.952,1802.48mil) And Pad U1-1 (3677.52,1872.362mil)

问题4.
这个警告是不是因为我还没有布线而产生的？

警告1和警告2，我想知道那个不合适的距离在哪？

问题5，
从这些警告信息由没有直接跳转到PCB里对应的位置？

问题6，
选中PCB里一个元件有什么办法直接跳转到原理图中对应元件的位置。

第一次画PCB,问题比较多，高手勿喷，
不想做一个不求甚解的人，
