New Concept on Training Projective Drawing

摘要

In order to develop the ability of students in spatial modeling, it's necessary to add a step named "reflection and intersection", focusing on the transformation from 2D to 3D, to the training of descriptive geometry and projective drawing, it means to perform 3D rebuilding, locating and measuring, from 2D geometry elements. With the help of software "Projector", user will be able to get 2D projections from 3D point, line, plane and solid, or to solve 3D problems with the known 2D projection in 3D environment.
