Pencil
Ruler
Paper (When drawing orthographic drawings a good tip is to use squared paper if possible. This will make the object easier to draw when drawing the object to scale.)
45 degree set square (optional)

There are two particular ways of drawing orthographic. These are known as first angle and third angle. They differ only in the position of the plan, front and side views.
Third angle
This angle is more commonly used in Europe.
An L-shaped object.
The Plan View of the L-shape is drawn as a 'birds eye' view, a view from above. The Front View is drawn as if stood in front of the L-shape. The Side View is drawn as if stood at the side.

The correct position of each view is shown below.

An orthographic can have more three sides drawn if the object
has unique sides that would not be described clearly by just three images.

Scale Drawings
The best way to do this is with squared paper, with one square
equalling 1cm.
