Ok this may sound dumb, but the reason i could never accomplish anything in this room is I didnt know to keep adding cross sections. I do have one question about it tho. I can keep adding cross sections on the Y axis but can I add them on the Z axis or X axis? I am also guessing you changed extrusion settings from pic 5 to pic 6 b/c I see the green line on the floor of the working box? Anyway with art I find that I am able to take rules & proceedures to adapt to what I need to do, but I am very slow to figure them out for myself :) Looks like I have to spend some time in the spline room for a bit :)
