Goran, Thanks. Ive always known about the Boolean Method. Im definitely using it for my fuselage doors and cabin windows. But a little insite? There different options: subtract, intersect, knife etc. Im always confused on which one I should choose. I make a simple object the shape of a window and I cross it with my fuse object now Im wondering which should I choose to make a hole in the fuse the shape of my window object?
