1. Draw two lines: one from a corner of the square diagonally and another to the  opposite diagonal.

2. At the point where the two lines meet in the center of the square, put the metal point of the compass—A.  The pencil point goes on the corner of the square--B.

3. Arc the compass over to the other side of the square—C.

4. Draw a line extending the side of your square along the top of the arc and finish making a rectangle.  

You now have 2 sizes to work with inside the whole piece.  Instructions for finding additional dimensions to use within your orthogon can be found at the Design Application link.  Often all that’s needed is a small, medium and large distance—sometimes with a very small, just for interest.
