Embodiment Construction
[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:
[0041] Such as Figure 1-Figure 5 Shown: a method for generating the central axis of an arbitrary quadrilateral surface for three-dimensional data processing of products, which mainly includes the following steps:
[0042] In the step of model decomposition, the sides of the quadrilateral are grouped figure 2 shown. Each side of the quadrilateral is divided into two groups according to the principle of "sides are not adjacent to each other", A 1 and A 2 as a set of constrained edges, edge B 1 and B 2 is another group, which are used as the starting edge and the ending edge respectively. The main consideration for selecting the starting side and the constrai...
