[0084] Step 1: Analysis of topological lines on the surface of special-shaped holes
[0085] (1) Classification of topological lines on the surface of special-shaped holes
[0086] The topological line classification of special-shaped holes is to separate the topological lines of the upper and lower end faces. First set a parity standard quantity k, and then traverse all topological lines. According to the characteristic that only the hole axis can have a straight line, add 1 to k when traversing to a straight line, otherwise judge the parity of k, and divide the topological line according to the parity of k They are stored in the upper and lower end line containers (ListUp, ListDown) respectively, and finally the upper and lower end lines are stored separately.
[0087] (2) Calculation of positioning points on the end face of special-shaped holes
[0088] The anchor point of the end face of the shaped hole is the closest point between the end face and the center of the hole...
