Part One – THE PENCIL
PLANOMETRIC PROJECTIONS
First introduced by Auguste Choisy at the
end of the 19th century, and the favoured
system of Le Corbusier and Theo van
Doesburg, these projections were primarily
produced for architects. This type of
presentation gives a truer, three-
dimensional illusory understanding of the
space and form of a building produced from
a plan in scale, and has become very popular
among architects.
