Hi. I'm trying to make a board and then send it off to a board house for etching. I made the autorouter make the traces for me, both top and bottom traces with vias and all. The thing is that I have both SMT parts and through-hole parts on my board, but the autorouter doesn't seem to care. It sends top layer traces to my through-hole parts, how do I fix this?
Yeah I thought about that, but there are alot of through hole components that simply cannot be soldered to on both sides (not by me atleast). Resistors, ceramic disc caps are probably easy to solder on both sides, but how do one go about doing that for a 4700uF 50V electrolytic cap? On my board I have two minijack connectors and a dual sided pot with a switch. The top contact points for these will be completely covered, so this can't be soldered to the top layer. Couldn't this be an issue for professional people aswell? Why do eagle assume that all through-hole components can be soldered to both layers?
I also wonder about those vias. Will a PCB manufacturer care about how many they are? Or can I litter the board with vias and still get the same price? I'm just picturing that they take longer to make

Eagle assumes nothing. You assume something wrong. A via is a little
metal pipe connecting bottom and top tracks without any solder. The wire
of a through hole component is going thorough the "pipe" and is soldered
at the bottom only. It does not matter if the top is covered by the
component since the connection to the top is made by the via itself
already. Check the internet for pcb and via.

You get the answer from the manufacturer of your choice...
