Parametric Mass of DynaBim Advanced Tuts

Hi,
I’ve learn the video tuts from “Learn” of DynamoBim.org section: great job, very interresting! (DynaBim/Learn/AdvancedTutorials).
I’ve also tried to redo the Revit parametric Mass “Introduction.rvt”, but I can’t :(.
This use a lot of intelligent params, refence points/lines/plane etc…
Think it’s important to understand this in background.
Do anyone know if there is a tut about this Revit File too?
