Hello friends ! 1st: Thank you very much for this great forum and the great people here - I love it !!!!!!!! :bgreen: Now, I want to try to model a very simply tire for an old airplane. It looks so easy, but the way to model seems to bee as not. What I want to have is that on the tire you can see around a profile. I´ve tried it with a nurbs torus - and than I´ve inserted more and more isoparms, to get more possibilities for the hull. hmm, well, my tires looking like gummiballs or round chewinggum: lol: Which method prefers modelling it a tire? hmm, thank you soo much for every little hint, help and/or information - sorry for my bad english. thx --> the never giving up bernhard (lol; now I´m addicted in nurbs modelling)
