(1) Construct a Hexagon - First Method, (figure 27). Let's assume that we have to draw a hexagon D across the opposite corners. To construct a hexagon, perform the following steps:

1853 Compass

Step 1. Construct a circle of diameter D. Diameter/2=radius. Set a compass to the radius dimension (view A).

Step 2. Using the compass, mark off six distances D/2 as shown in view B. Step 3. Draw in the hexagon (view C).

This is the classical geometric method and is not generally used by draftsman because it makes positioning of the hexagon difficult.

(2) Construct a Hexagon - Second Method, (figure 28 on the following page). We will construct a hexagon S across the opposite corners by performing the following steps.

Step 1. Construct a circle of diameter S (view A).

Step 2. Define points 2 and 3 as shown in view A (figure 27 on the previous page).

Step 3. Using points 2 and 3 as the center, construct two arcs of radius S/2 (view B).

Step 4. Define points 4, 5, 6, and 7 as shown in view C.

Step 5. Draw in the hexagon (view C).

(3) Construct a Hexagon - Third Method, (figure 29 on page 38) . Let's assume that we have to construct a hexagon A across the opposite corners. Construct it by performing the following steps:

Step 1. Construct a circle of diameter A.

Step 2. Using a 60° triangle, construct lines 60° to the horizontal as shown in view A.

Step 5. Draw in the hexagon (view C).
