*begins to have flashbacks of my Computer 3D Modeling course and those darn planes...* That reminds me of the time I had to model a plane for a course...I did not have to model a Boeing, but I used an American West Boeing 737 to practice with in order to learn how to use Rhinoceros 3D and also to have a basis idea of how I could model the plane for the class...I would have finished it too, but the program kept on freezing and crashing when I tried making a row of seats inside the Boeing. I made the entire row of seats outside the plane first, but when I tried moving them into the plane body, my program froze and crashed each time...I gave up after 2 or 3 consecutive tries of rebuilding the seats and putting them into the plane.
