Crap. I couldn't undo enough to get back to the original object design. (before I started the boolean stuff) So, I rebuilt the entire thing, which took an eternity, and saved. I tried it again, this time deleting the history each time after I did a Boolean. I got up to nine and couldn't go any further. It did the exact same thing. There must be some kind of limit as to how many times you can boolean an object depanding on its shape or the number of polygons it's made up of. This really stinks b/c I could have made it look cool. Hey! *idea suddenly pops into his head* I might be able to get it to work if I combine all the duplicate cylinders and make them into one object. Then I just have to boolean once. Ha! I hope it works.....
