Scale drawings are used by architects, engineers, interior designers, ship builders, and others. In a scale drawing each unit measurement on the drawing represents a fixed length on the object being drawn. For instance, in an architect’s scale drawing, 1 inch on the drawing may represent 10 feet on a building. The scale describes the relationship between the measurements. If the measurements have the same units, the scale can be expressed as a ratio. In this case, the ration would be 1:20, representing 1 inch to 120 inches (or 10 feet)
