Crab, I thought I had a picture but can't find one. Visualise a coke can that you stepped on and only partialy crushed - that's what a 3-D cam looks like, only it's designed like that. Another way to think of it is if you have seen the 3-D computer drawn fuel scheduling/mapping graphs that a car ECU uses, then carve one from a cylinder of metal.
Having said all that - the 212 looks like the latest in FADEC control when viewed side by side!
