Ah it is easily done with one layer but what I am trying to do is multiple layers here look at this. I have 4 layers here but not the way I want them. I have all spheres positive except the core, then two squares bisecting negative. but do you notice that it doesn't do the layers quite right. Try mor then one layer and let me know how that ends up...I have been bugger'n with this for awhile (no offense). But my boolean is not that bad lol
