Principles of Orthographic Projection (正投影法原理)



  • Form of projection                                       投影的形成

  • Types of projection                                      投影法分类

  • Features of orthographic projection          正投影的特性

  • Three-view drawings                                    物体的三视图


Projection method :  When the line of projection passes through the object and the pre-established plane, there will be graphics produced on the plane. This method is called projection. 

投影法: 投影法是投射线通过物体,向选定的平面投射,并在该面上得到图形的方法。
