and that part deals with making the back wheels. Because he first had made the wheels like the front wheels but, the back wheels of the semi are different. The wheel goes in.
So I had trouble making the wheel like in the tutorial so I looked up a picture of a semi wheel and made it. Then when it came time to spin the nuts for the wheel I was able to get the spin to work.
I was surprised and delighted. I used the spin tool then on the last operation panel I zeroed out z and put 360 for the angle for the steps and adjusted the x and I was surprised to see that the spin worked and there were nuts in a circle around the wheel.
So I re-did the from wheel nut spin but, it would not work. It turns out all I had to do was add a face on the back of the nuts and the spin worked.
I had deleted the back face of the nut and when I tried to spin I would get a face between all the nuts that were spun. So adding the face back to the back of the nut made the spin work right.
I never thought I would ever figure out how to use the blender spin tool. I am glad I was wrong on that count.
