Creating one composite Eagle board from autorouted circuit segments?

[temp1PJACB]

I've found splitting an analogue design into smaller segments in order of signal flow removes the clutter of parts. I can more easily autoroute each segment to .sch and .brd files with different names. I've started building my own library of small schematic clips, each with an  autorouted board layout I'd like to use in projects. I suppose this is a 'How to merge' question'?

I haven't found out how to combine them into a single layout where previously auto routed circuit segments are left untouched by the autorouter?  I can copy and paste each .sch into a new file and add interconnections, but I'm generating a new board layout from scratch and not using previously error checked autorouted board segments.

The hard way is printing each circuit segment board layout, re-align the parts and hope the autorouter for the assembled segments on one board layout will re-route with the same result? But this is so tedious. Any help with a workflow suggestion would be appreciated?

Hello @temp1PJACB ,

Depending on which version of EAGLE you are using you may or may not have a solution. More recent versions of EAGLE have the import EAGLE drawing option. Doing this from the schematic of a consistent board schematic pair will bring in the layout as well. I just checked and this works at least as far back as V7.7 of EAGLE.

Just go 

File > Import > EAGLE drawing.

Let me know if you run into any issues.

Best Regards,
