The issue of space geometry is diagrammatical calculated mainly by orthographic projection. But it is difficult or no way out for some issues in making use of orthographic projection. In this paper the fundamental principles is introduced and used for diagrammatical calculation in space geometry. Moreover the application in descriptive geometry is also enumerated.
