    1. To make a double vanishing point perspective drawing of a box, you can start bydrawing a horizon line and one vertical edge of the box as shown below.
    2. Then draw construction lines from the top and bottom of the vertical edge to two vanishing points on the horizon line.

    1. Once you have done this, you have to mark off another edge of the block on the construction lines as indicated in Figure 5 at A and B.
    2. From points A and B, draw construction lines to vanishing point 2.

      Figure 5
    1. Now mark off another edge of the block on the construction lines going to vanishing point 2 at C and D as in Figure 6.
    2. Draw construction lines from points C and D to vanishing point 1.

    Instead of drawing lines, you can use your pen, pencil or any other drawing tool to make dots for shading. The closer the dots are together, the darker the shade will be. Tech1_gr8_ch4_NewFig14.tif
