Produce an elevation and an end elevation of the
object. Next position the object in plan view at
the correct angle for the perspective projection.
The picture plane in this example is drawn behind
the object
3
Now from the spectator point produce two
construction lines parallel to the viewed
surfaces.Project these to the picture plane and
then vertically upward to meet the eye level
line. Where these lines intersect is the position
of VPL and VPR. Now repeat the process projecting
lines from the viewed surfaces to the picture
plane and vertically upward to the ground line
providing two height lines

Mark on the left hand height line, the two
heights. Then produce perspective lines from the
left hand vanishing point through the height
points, Now view the relevant points on the left
hand facing surface by producing lines from the
spectator point, through the corners on the plan
to the picture plane then vertically upward to
the relevant perspective line

From the corners of the surface created in the
last frame, project perspective lines to the
right hand vanishing point as shown.Also view the
right hand surface, project to the picture plane
and then vertically to the space above.
