Study the cross-section line problems in descriptive geometry based on perspective affinity transformation

    Abstract
  • In descriptive geometry,it is always complex and with low precision to solve the cross-section line of a general plane and a solid surface.In order to solve these problems,this paper introduced a method of perspective affinity transformation and its application in solving cross-section line.It has been proved that the presented method is very simple and effective.
