Hello, is there any way I can do a servation in a figure by the intersection of another. I have a box size 100x100x100, and I want a face shape has a heard of another case or any other entity included in the prefabricated motor.

it would look like this photo

There are no CSG processes built in to do that sort of thing, but you can create a compound body composed of multiple other (usually convex) shapes. There's also the option of using MobileMesh, if this is something that needs to move. The compound approach will be usually quite a lot faster because it tends to have far fewer shapes involved. High-detail meshes can get expensive.
