This will complete the left-hand batter post. Drawthe right-hand batter post in a similar manner. We arenow ready to draw the 3 X 10 sway-braces which connectthe opposite ends of the ground sill and cap. From and tothe left of the lower right-hand corner b of the ground silllayoff a distance b in of 5 inches; ixoxw and below the upperleft-hand corner c of the cap lay off a distance e in ofG inches; join the points ni and vi \ then draw a line parallelto VI ni at a distance from it equ
