Cool, Thanks for the help guys!
BTW, i still can't get number 2 to work. I select the layer in the layer box I want to work with. I then press the blue up and down arrows but that only brings layers forward or backwards in your line of sight. I still can't seem to highlight a different layer after some other layer has been selected. For instance I import the fission rods. Then I import the sun. Now I want to go back to the fission rods but I can't seem to select it to resize it or whatever.
