This document provides instructions for creating an orthographic projection drawing. It explains that an orthographic projection shows the front, side, and plan/top views of an object all drawn to scale. The document guides the reader through each step, starting with the side view and adding the top and end views along with guide lines. It asks students to practice drawing an orthographic projection of a pen and includes questions to check their understanding of what orthographic projections show and the symbol used to represent this type of technical drawing.

by the end of the lesson you will have learnt;
How to layout and create an Orthographic projection
drawing and what symbol is used to represent this drawing
type.
W.I.L.F. what I am looking for;

4. How do you draw this
shape in Orthographic
projection?
Year 7 – Orthographic

5. Year 7 – Orthographic

6. Start with the side of
the shape first
Year 7 – Orthographic

7. Then draw the top view of
the shape.
Draw guide lines (grey lines)
to get the right size.
Draw the top / plan view
about 20mm above the side
view.
Year 7 – Orthographic

8. Then draw the side
view of the shape.
Draw guide lines (grey
lines) to get the right
size.
Draw the end side
view the side distance
between the side and
top.
Year 7 – Orthographic

9. 45 degree line
Then draw a 45
degree line from the
corner of the side
view.
Year 7 – Orthographic

10. 45 degree line
Now draw guide lines
(grey lines) from the
top view until they
reach the 45 degree
line.
Year 7 – Orthographic

11. 45 degree line
Now draw guide
lines (grey lines)
down from where
the guide lines
just drawn reached
the 45 degree line.
