multiple versions of PCB without redoing all routing

Question

Hello,

I would like to design a PCB containing a digital and an analogic part.

The analog section (most of pcb area placed on the left of the PCB) is always the same, while for the digital section (on the right) I should realize multiple versions.

How can I make with Eagle to do the routing once for the analog section

modify only the digital section in the schematic and keeping all the routed analog part? One dimension of the board may vary according to the complexity of digital section.

Thanks.

Design the analog portion of the project and route it the way you like. Then create a new project containing the digital portion of the design. You can simply import the analog design pre-routed into that particular digital version, or any different versions in the future.
