It looks outstanding to me. That grey model with visible topology is great.
Could you tell me what have you meant when you wrote “no knots”? I have problem to differ curve knots from control points. I’ve thought that is same. I`m a fresh Rhino user and I have headache from isoparm/curve/edges differences and knots/control points differences.
Have you made multi-span surfaces which have been split to smaller patches?
How have you constructed curves for building surfaces? Which tools have you used for that (control point curve or rather curve interpolated points)?
Have you rebuilt every curve after construction to have 3,5,6 and 7 control points?
What tools have you used for surfacing from curves (blend, sweep, loft)?
Do you think it`s faster to do a car model in subd or nurbs?
Amazing piece of work.
