I am in the process of going through the Carrara Studio 3 Handbook by Mike DeLaFlor and on the first tutorial on building the airplane it leaves out some very important information and just assumes you know how. The part I need help out with is this, it tells you to place two planes perpendicular to each other in the assembly room and attach the tif images of the airplane to each of them.

I was able to play around with the planes and get them somewhat at 90 degree angles to each other but it seems like there should be a easier way. Also each time I inserted the plane it was loaded on the floor. Is ther a way to load it against the sides? And how do I attach the tif images to the planes? And is there any difference between inserting a plane and a infinite plane?

If I can get this information I can proceed on...
