Help! How to CAD model the transmission housing using Core and cavity method?

[kar0]

Hi all,
I am unable to find an idea on how to model this housing using Parametric Core and cavity method in NX, like inner and outer core. Can somebody provide me the general idea/framework in how to model this? I dont know where to start.

I'm a bit rusty in NX bc its been a few years, but in Creo I'd start with a pair of solid blocks the size/shape of the core boxes and "remove" your bellhousing model from the cope&drag to get the basic shape, then modify as needed.
