This is my spaceship. I made it in 3d max. First i made a bot with 5 length, width and height segments. Then i deleted all the polygons on the inside face and cloned it as an instance. I did this because when you clone something as an instance anything you do on the instance copy's over to the non instance object that it is a clone of. Then i turned it into an editable mesh and I edited it
Then I attached them together using the attach tool and then i welded them.
