How is it possible to create pattern for cut material body. The problem is that i can't choose cut material body as geometry for Pattern

[Rob]

Pick the "sides" of the hole and pattern that.

I cant. I need to make holes inside the cube like this one 

But i cant choose this body (Hole) for Pattern, and if you select 6 sides of this hole it also does not give any results

[Pixinot]

Or another question. How i can make body inside body. When i switch the small box to "Add frozen", "Mechanical" thinks that big box just go through small box without interaction each other. So how to make a small box with one material inside the big box with another material and make a contact with them

You need to split out the geometry. Multi-body parts might do that, but (safer) is to slice or subtract+retain.  Basically, in CAD you just need to show people where things are, in simulation we need to actually represent the bodies and their relationships. 

Re the first question, have a look at pattern, Named Selections and subtract. It's possible, but you need to do it in the right order.
