side of the cube away from the center of the cube.

Remember the station

point is the spot from which you ill view the cube. Now place a line that

represents the picture plane between the station point and the square so

that it touches the front of the cube.

It is not essential to place it

here; it may be placed at some other distance from the cube. However, the

farther away you place in picture plane, the smaller the cube will appear.

In any perspective drawing, the comparative sizes will be reduced

proportionately as the distance is increased between the picture plane and

the object.

4. Locate the corners of the cube on the picture plane by drawing lines B

(fig 1-3) from each corner of the square to the station point. (Each corner

of the cube represents the positions of a vertical corner of the cube.) The

positions of tie verticals on the picture plane are determined by the points

of intersection of these lines with the picture plane.

In order to

determine the width of each side of the cube, drop vertical lines A and C

from the points where the lines A and B intersect the picture plane.
