Hello, I've done 4 layer projects successfully using EPCB and their software.
Now I'm converting the project to 6 layers, with added capabilities, and have chosen Eagle since the board manufacturer I've had to switch to favors this program. I've downloaded the manufacturer's .dru file for a 6 layer board. Now I'm trying to figure out how to assign which layer a via connects to. Presently, the .dru file is only letting me connect from the top to the bottom layers.
Also, since this project uses 256-pin BGA's I don't use schematics. I would like to do this starting from scratch in PCB design.
So how do I go about assign a layer to a via? Thanks
