  • Doors: Door symbol is presented by the straight line and the arc shows the opening projection of the door.
  • Stairs: It is basically drawn by parallel lines which is generally located between two windows.
  • Windows: The symbol of window is basically denoted by three lines.
  • Walls: Walls are generally two types; interior walls and exterior walls. Both walls are drawn by two parallel lines but exterior wall lines are dark, thick and interior wall lines are light.
  • Appliances: These are basically the other symbols in floor plan which are bathtub, toilet, sinks, other furniture, etc. All appliances symbols are drawn by single lines.
