electrical box demo

we started with a box 

we did a slice in the middle 

I had inset both sides of the face

we then extruded the faces

and extruded the top by local

we then selected 1 line and dragged it down the z axis 

and extrude the bottom back on group

we then set up the texture on the material editor

now we affected the pivot points 

and we ainmated the doors using the auto key 

Here is the outcome
