第一次画PCB出现好多警告

警告1，
Silkscreen Over Component pads (Clearance=1mil) (All),(All)

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，
