-is an exact projection from horizontal or vertical plane surfaces at 90 degree angle.
-example :
-the primary planes intersect each other at right angles.The angles the horizontal and vertical planes
are described as first,second,third and fourth angles of projection.In theory,you can place an object
in any of these angles of projection and draw or project its image onto the projection planes, which in
turn could be rotated onto the plane of your drawing paper.Only first and third angle projection have
a practical application today.
