this is driving me crazy. how can I drill a drainage hole through the all the surfaces? the cylinder represents where I want the hole to go. I made the fins rack with the polygon tool and then extruded, and the cylinder is the circle polygon and then extruded. I set the tools to object mode, then I click on the rack, then I add the cylinder, and then I do object->boolean-> subtract, but its all messed up. Whats the right way to do this?
