Eurocontrol is fun! The first place I'd start is the Route Catalog in the secure CFMU website. Right hand side of the page, in the same area as the validator (Free Text Editor).
Plug in, for example, LFPG to KJFK/KPHL/KCLT/KORD and it will spit out all kinds of routes to various transition fixes.
Once you do that and get a route that validates save it somewhere! After you do that for 30 or so, you'll start to figure out where fixes and such are and be able to piece together routes. I have a feeling things are somewhat simplified with us using SABRE though; I can look up every airway to see the points on it.
When all else fails remember, "Will accept IFPS changes ". I was bored and just playing with routes the other day out of Amsterdam. For the life of me i couldn't get a route to work avoiding northeast France and ending up over a southern transition point. Built a direct which I knew wouldn't validate, filed it with "Will accept IFPS changes" in the strip and after a few minutes i got back a good route. Don't like doing that, but I was stumped.
