Draw a line back through the lowest point from the 30 degree angle on each side. Draw a horizontal line through the lowest point, and using the protractor, mark out a 30 degree angle up from the line on either side. Using the ruler, draw a vertical line on the page, and mark three equally spaced points along it. You will need a piece of paper, ruler, pencil and protractor (or for the shortcut version, using gridded paper, jump to the next section).
The most common isometric drawing is that of a cube, and drawing a cube using isometric projection is very easy.
