An isometric drawing is built around three lines called isometric axes, this comprises a vertical axis and two receding axes. Note that the two axes are at angles of 30° and there is 120° between the three axes, they are called the isometric axes and on them, the drawing is built up.

Vertical lines are drawn with the right angle of a set square and lines at 30° are drawn with a 30° set square.
