Prepare exterior elevations.

Preparation should include

• setting the scale of the drawing
• using the floor plan to project horizontal lengths of exterior walls, doors, windows, and other elements
• using the wall section to project heights of the grade line, depth and thickness of footings, door and window heights, eaves line, and roof height
• adding details such as railing, window muntins, trim, window wells, and gable ventilators
• adding dimensions, notes, and symbols
• identifying each elevation as front, right, left, or rear (or north, south, east, or west) immediately below the drawing
• identifying grade lines and finished floor and ceiling levels
• identifying roof features, such as slope, and chimney height and size.
