Fine stepped truck bonnets - how do you build?

[CRookie28]

Hi there, I'm looking to understand how people build fine graduated bonnets on trucks, at half a brick/unit difference to seemingly even finer, as the bonnet increases in size from front to windscreen.

Has anyone experience of this or know how it is done? 

I can imagine it can be achieved using a modified 1 x 2 plate with a stud at half way along and then building on top of that but wondering how others have achieved this effect.

A good example is this one,
