IntroductionIntroduction
• Elevations are drawings that show object height o When builders and architects refer to building elevations,
they mean exterior elevation drawingso A working drawing set includes elevation of the buildings
four sides A complex building may have more A simple building may have less

• Helps to determine the relationship of one drawing to another
• Elevations are named according to compass directions (e.g., side that faces north is the north elevation)o Allows them to be oriented to other plans
