The document provides instructions for drawing an isometric square with each side equal to the diameter of a circle. It explains how to draw the horizontal and vertical center lines of the square and its diagonals. It then gives directions to draw construction lines from two corners to the midpoint of another side, and to use the intersections as centers to draw arcs with a compass to complete the four corners of the isometric square.

1. Drawing the Isometric Square
Draw an Isometric Square with each side the same size as the diameter of the circle.
Draw the horizontal and vertical centre lines.

2. Drawing the Isometric Square
Draw the diagonals of the square, as shown.
The corners are labelled to assist in the explanation of the drawing technique.

3. Drawing a Construction Line
© J Lewis 2004
Draw a straight line with a ruler or set square from the corner C to the mid
point of AB.

4. Drawing an Arc
© J Lewis 2004
Use the point of intersection of the line from C with the diagonal BD as the
centre and draw the arc as shown with compasses.

5. Drawing another Arc
© J Lewis 2004
Repeat using corner A and use the point of intersection of the line from A with
the diagonal BD as the centre of an arc and draw as shown with compasses.

6. Drawing the Third Arc
© J Lewis 2004
Use the corner A as the centre of the arc and use your compasses to
complete the third corner as shown.

7. Drawing the Fourth Arc
© J Lewis 2004
Use the corner C as the centre of the arc and use your compasses to
complete the last corner as shown.
