Thx Pilou, but I don't think it's what I've been looking for. It's awesome, but it seems it is a bunch of ready objects that can be used for kitbashing.
What I'm searching is a way to "stencil" intersection of the objects onto one of them. In many apps (Modo for example) it is called "boolean stencil". It is much more general type of tool, allows you to add extra edges / patches onto the object and you can use those for creating insets etc. Another benefit it allows you to work within single solid, you don't get several touching or intersecting ones. If my intention is not clear let me know - I'll try to work out a video.
