Hi, I’m designing a PCB based on a proven bass guitar preamp schematic, I have two questions.
I’m designing my first PCB in eagle (no schematic, straight to PCB.) When I add a part, do I also need to specify the holes for through-hole components in the library?
Also, I understand that batchPCB plates all drill holes. Is it plated through with a big enough pad to solder the board from the back, or should I use vias for my through-hole components?
Thanks,
Adam

It would make your life easier. You can specify holes using the “pad” tool, the one that looks like a green donut.

When laying down vias just set the Diameter drop-down to auto and you should have plenty of room for soldering. Same deal with pads when specifying the part in the library.

I would recommend you draw up a schematic in eagle even though it sounds like redundant work its going to save you a lot of error checking on the PCB. In my opinion your actually going to save time doing schematic and pcb rather than just pcb depending on the circuit complexity I suppose.
Hope that helps, have fun and good luck with your first board!
If you mean, do you need to put the pin holes down after you have placed the part, no. They are part of the package.
Trying to do a board without a schematic in Eagle causes a lot of problems. I would suggest trying to put down as much as you can in a schematic editor.
Thanks for the reply all, I will give the schematic editor a shot. It’s not too complicated of a board, but it would be nice to find any errors before ordering and stuffing it. Thanks!
