ISOMETRIC PROJECTION AN EXPLANATION |
| V. Ryan © 2007 |
| Isometric drawing is way of presenting designs/drawings in three dimensions. The example below has been drawn with a 30 degree set square. Designs are always drawn at 30 degrees in isometric projection. It is vital that drawing equipment such as T-squares and 30/60 degree set squares are used carefully. The drawing paper should be clip securely to a drawing board. |

|
| 1. Draw two basic 30 degree guidelines, one to the left and one to the right, plus a vertical guideline in the centre of the drawing. In this example three edges of the cube have been drawn over the guidelines (they are slightly darker) |
|
| 2. Draw guidelines to help you start constructing the left and right sides of the cube. Remember to use a 30 degree set square for the 'angled' lines. |
|
| 4. Complete the top of the cube by projecting lines with the 30 degree set square as shown below. |
|
| Shading can be quite important. First try producing a simple outline (dia A) and then try the shading techniques seen in dia C and dia C. See previous sheet for shading techniques. |
