The Isometric Cube
Isometric Drawing of a Cube - 1
The Isometric Cube is the building block of isometric drawing. Its three dimensions are represented by three equal planes  that sit on three axes (red lines). The vertical axis sits at 90° to the horizontal (green line) while the two horizontal axes sit at 30°.
Isometric Drawing of a Cube - 2
A simpler method of constructing an isometric cube is illustrated above:
- Draw a regular hexagon .
- Draw its diagonals which become the interior edges of the cube.
- Erase the dotted sections to create the three front planes of the cube.
- Shade each plane with an appropriate tone to enhance its form.
