MEASURING POINT METHOD
Measuring Points
A measuring point (MP) is a vanishing point for aset of
parallel lines used to transfer true dimensions along a
measuring line (ML) to a line receding in perspective. The
diagonal point in one-point perspective is one example of
such ameasuring point.

In two-point perspective, you canestablishtwo
measuring points (MPL and MPR) for
transferring dimensions along the ground line
(GL) to the two major horizontal baselines that
are receding in perspective.

To determine the location of these measuring
~ points in the plan diagram:
~ With the major left vanishing point (VPL) as
the center, swingan arc from the station point
(SP) to the picture plane (PP). This
intersection is MPR.
• With the major right vanishing point (VPR) as
the center, swing an arc from the station point
(SP) to the picture plane (PP) to locate MPL.
• Include vanishing points for secondary lines
that might be useful in constructing your
perspective. For example, if you have a series
of parallel diagonals in your design, establish
their vanishing point as well.
