Module 2 : Theory of projections

Lecture 17 : Projections of points

Figure 4 shows the planes and the position of the points when the planes are partially rotated. The arrows indicate the direction of rotation of the planes. The three views after complete rotation of the planes is shown in figure 2. 

Figure 4. Projection of the point “P” on to the three projection planes after the planes are partially rotated.

The procedure of drawing the three views of the point “P” is shown in figure-4.
