Perspective

Key Concepts:
  • Vertical lines remain vertical
  • Horizontal lines go to a vanishing point
  • Find beginning and end of sloping lines, then join the dots

Equal Widths

Key Concepts:
If you have a line of unknown or awkward length (125.32mm),
  1. draw another line that you can easily divide into the amount of sections you need at an angle to the original line 
  2. divide it up
  3. connect the end of the last division to the end of the original line
  4. draw lines parallel to the line in step 3 from each point
  5. the points where these lines meet the original line give you your divisions

There are two ways to divide up the line (step 2):
  • use your compass to mark off equal divisions
  • make the line a length that is easily divisible, ie, for 7 divisions use a 140mm line

​Very Important - You MUST you the construction method above, measuring the length and dividing it isn't accurate and will get you 0 marks.

Bisecting Angles and Lines

This is a technique used within a range of short and long questions. See page XXX in your book for details of how to do this.

Drawing Hexagons and Pentagons

There are several ways to draw each of these so don't worry if you forget a part of a technique, there's always another option. Usually, using your compass is faster and easier than other methods.

Key angles
Pentagon (5 sides) - 72 degrees   (360 / 5)
Hexagon (6 sides - 60 degrees   (360 / 6)

Isometric (Short Questions)

  • Pictoral = 3D
  • Horizontal lines become diagonal (at 30 degrees - use the dots)
  • Vertical lines remain vertical
  • Count the gaps between the dots to work out the length of the lines
  • Don't forget to colour or shade the sketch
