ORTHOGRAPHIC PROTECTION—WINDOW FRAME 189 there must be a rough sill and a rough head (dooropenings have similar heads but not the sill). Forpresent purposes the exact position for the rough sillis an arbitrary matter, except that it should be soplaced as to accommodate all that is to follow. Wewill fix its position therefore as shown in Fig. 104to the left hand of the sheet and on a line sufficientlyabove the Plan to permit all necessary detail beingdrawn in connection with the elevation. The roughsill is a bit of studding, and a 3x4 will answer thepurpose, and as in the plan, the 4 way is thicknessof wall. The finished sill 2 thick, is now drawnwith the under side in contact with the outside arris(edge) of rough sill at c.
