I'm currently out on placement from an automotive engineering degree and have been using NX daily, used to use solid edge at uni, and I can appreciate how much time you must have spent on this! How detailed are you going with the modelling? Are you doing things like washers, shims, nut, bolts etc, as if you are it could be a very powerful tool for teaching about dismantling/rebuilding the a series - good work
There has just been a big update in NX. And my Torrettes is back.
And I have the ventilation system of a car to finish.
