Oblique Projection
The given views show
the orthographic
views of a mantle
clock.
• Draw an oblique view
with corner X in the
given position.

• Do not add the hands
of the clock to your
drawing.

Drawing Oblique Crate
Start the oblique view
by drawing a crate to
fit the clock into.
In this case the size
of the crate will
enclose the body of
the clock but does not
include the clock face.
This will be added to
the main drawing
later.
For Standard Grade
drawings the depth of
the crate should be
drawn at 45 o with the
size measured at
either full size or half
full size. In this case
half sizes have been
used.

Drawing Clock Top
Draw the top curve of
the clock body on the
front surface of the
crate.
Project the centre of
the curve back at 45 o
to locate the centre of
the back curve.
X
Draw a 45 o line
through each centre
to find the tangent
points where the
curves are joined by
straight edges.

Drawing Clock Face
Draw the circle for the
face on the front
surface of the clock
body.
Locate the centre of
the clock face at the
very front of the
drawing.
X
Remember that the
distance in this drawing
is half of the full size.
Draw the outside circle
and the inside circle of
the clock face.
Locate the tangent
points on the face
circles and add the
straight edges required.

Drawing Clock Base
Add the feet details to
the drawing.
Remember to use half
sizes for any
dimensions which are
measured along 45 o
lines.

Finishing Drawing
To finish the drawing,
darken in the outlines
of the oblique view.

Alternative Oblique View
At Standard Grade an
Oblique View may be
drawn with the
dimensions on the 45 o
angles at full size or
half full size.
The two drawings
shown here show the
different views
generated by both
methods.
