| The first exercise is to draw a simple independent three tread unit laid out in first angle projection.
| |
|
| |
|
| Below is an example of first angle projection. The projection lines are still visible; these lines show how sizes can be transferred from one view to another.

| For the purposes of this exercise the dimensions of the tread unit are as follows.
| |
|
| |
|
| *Overall length of treads: 2000mm

| | |
| The second exercise is to draw a flat in first angle projection that has an arched window inset in the centre of the flat. There is an example for reference in the following pages.
| |
| | |
| For the purposes of this exercise the dimensions are as follows.
| |
| | |
| *Overall height of the flat: 3000mm
| |
| *Overall width of the flat: 2000mm
| |
| *Width of arched window: 1200mm
| |
| *Height of arched window: 2000mm
| |
| *Radius of arch: 600mm
| |
| *Height of window from base of flat: 600mm
| |
| *Thickness of flat: 25mm
| |
| *Depth of window return: 200mm
