Describe the purpose of the angle of projection block and name the two projection formats.
What will be an ideal response?
The angle of projection block specifies how to interpret a drawing according to the method of view projection. The THIRD ANGLE PROJECTION notation and related symbol means that the views on the drawing are created using the third-angle projection system. The other option is FIRST ANGLE PROJECTION.
