Traditionally, the top layer is the one on which through hole components are mounted with their leads looking through to the bottom layer. The PCB Editor view is always looking down on the top layer. Surface mount components are often mounted on the top layer but that somewhat depends on the manufacturer's choice of wave solder (SMD on the bottom or top layer with the board run through upside down) or reflow solder (SMD on the top of on the bottom with the board run through upside down). How you use the layers of course depends on your application

Thanks for the replay, I will have to remember this. I was having issue figuring out why my wires were not matching up. i was looking as solder side of my last board. This will make thing much easier

`...with their leads looking through to the bottom layer.` what I meant - before Autocorrupt changed it - was: `...with their leads` **poking** `through to the bottom layer.`
