Oblique Projection
An oblique projection is a 3D drawing of an object. It
shows the same three views as the 3rd Angle
projection. The side view is drawn first using the
same measurements as the 3rd angle. The end and
plan views are added in using a 45° set square.
Measurements on the diagonal lines are half size.

Construction lines – use a sharp H
pencil and make the lines as light
as you can.
12cm – 120mm
4cm – 40mm
Object lines – Use the same
sharp H pencil but press harder
to produce a dark line. This will
mark the side view stand out
from the construction lines.

Homework task - Toy car in Oblique Projection.
1)Page layout.
2)Oblique toy car – use the same toy car you drew for your 3rd Angle
Projection. Draw the car larger to fill more of the space. Show all the
details and render (colour) your drawing. Remember to judge the
proportion of the toy car so that the thickness looks realistic.
