USING THE ISOMETRIC GUIDES AND A FINE PENCIL,

DRAW THE FIRST ‘CORNER’ OF THE

CUBE.

CHECK THAT THE LENGTH OF EACH LINE IS THE SAME MEASUREMENT,

FOR EXAMPLE 40mm.

HAVE DRAWN.

THEN DRAW THE TWO TOP LINES WITH THE ISOMETRIC GUIDES

CHECK THAT THESE LINES ARE THE SAME LENGTH, AS ALL THE

OTHER LINES.

REMEMBER, THE SIDES ARE NOT ALL

THE SAME SIZE, THIS WHY THIS TYPE OF SHAPE IS CALLED A

‘CUBOID’.
