Oblique Projection
Department of Technological Education

• 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
Department of Technological Education

• 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 45o with the size
  measured at either full size or half full size.
  In this case half sizes have been used.

Drawing Clock Top
Department of Technological Education

• Draw the top curve of the clock body on the front
  surface of the crate.

• Project the centre of the curve back at 45o to
  locate the centre of the back curve.

• Draw a 45o line through each centre to find the
  tangent points where the curves are joined by
  straight edges.

Drawing Clock Face
Department of Technological Education

• 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.
• 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
Department of Technological Education

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

Finishing Drawing
Department of Technological Education

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

Alternative Oblique View
Department of Technological Education

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