The supercar is built with 5th order curvature! What is this equivalent to? That is, every time a curve is drawn, it requires more than 6 points.

When Rhino's one-line simplest surface modeling VS traditional approximation surface modeling, one-line simplest surface modeling wins!
In the early rhinoceros version, drawing each curve was quite painful. For example, when you draw 6-point curves, you must use 5th order, and 5-point curves must use 4th order. Later, the version was upgraded. After such a complicated construction was not needed, many designers used the order of points casually, forming many useless structural lines, resulting in uneven surfaces and unable to modify and adjust in real time in the later period.

When the project needs to be modified, it meets Rhino with a line and the simplest modeling wins!
The simplest aspect allows you to modify the scheme accurately in real time.
