In rhinoceros, two-dimensional use of curves to make texture effects, then flow the curves onto the cylinder, draw lines into surfaces with the intersection of lines, and then array them, and then OK. I don't know if you can understand, I did it this way, maybe there are other ways.
Thank you, probably know how to do it, how to make a gentle transition from the polygonal surface to the normal surface, similar to the effect of gradual recovery?
Eat ~ comrade, ha ha, your name suggests you change, I think it is wrong!
Excuse me, how do you make the cutting surface on the surface, and how do you make the cutting surface over the normal surface?
Your name... Absolute.
