A sorting algorithm for section data point is proposed,first the minimum enclosed polygon is built,then the data points is inserted into the polygon according to minimum length increase principle,a new polygon containing all data points is formed.

Fair fitting of the B-Spline surface based on section data;

Taking triangular-windows of car seal for an example in the article,in combination with the feature of car seal of reverse engineering and the theory of change of coordinate,the software of reverse engineering was adopted to realize alignment between the cloud data and section data of car seal.
