However, this flexibility brings a great deal of inconvenience to shape design for typical demand of design is not only qualitative but also quantitative, such as a global smooth and fair surface approximating a group of scattered points and interpolating a section curve .

但这种灵活性也给形状设计带来许多不便：典型的设计要求既是定量的又是定性的，如"逼近一组散乱点且插值于一条截面线的整体光顺又美光的曲面"。

Being formed by linear grain curved surface, helicoid can be expressed by a group of simple lines. Writing two equations of inside and outside of the helicoid, getting any one of simple line′s equation and from which getting the coordinations of two end points by projection transformation, the CAD system of helicoid is achieved. It...
