Abstract:
I. Product and its Uses
Diagonal scales are widely used by cartographers,
surveyors and Engineers in Measuring
or setting off distances upon geometrical and
other drawings, maps plans etc. with correctness
aimed at upto one hundredth part of milimeter.
Different materials are used for the
manufacture of these scales such as brass and
other rust proof materials. However this
scheme envisages manufacture of acrylic and
brass diagonal scale etc. Protractors are used
by cartographers, surveyors and engineers for
measurement of angle or laying out angles of
given values and checking angular work and are
made of acrylic sheets. Flat rules made of acrylic
or PVC material are used by surveyors by
joining two points for working on plane table in
the field.
Tringular scales are used in the measurement
of size and also to draw the drawing to required
scale. The scale is triangular in the shape made
from acrylic sheet.
