All plans should have a north arrow but only on floor plans and site plans only
Do not make it too fancy. Align the arrow with and place it near the drawing title.
Window symbols: Greatly affect the appearance of the elevation and have are drawn with as much detail as the scale permits.
Door and Window symbols: These symbols are drawn on detail drawings.
Section marks:
On plans only to indicate where each building and wall section is cut.
Do this in the same place on all plans if drawing a multistory building.
Elevation symbols:
Rooms with a lot of built in features need interior elevation drawn to explain them clearly.
The elevation symbol is placed in the room and arrows are numbered indicating which elevations are drawn.
The sheet numbers where they can be found is located in the center.
Room, door and window numbers and letters:
Each of these has its own shape.
Room number symbols are placed under room titles.(Figure 2)
Door numbers are placed within the door and its swing.
For non – swing doors, the symbol is placed inside or outside the door & sliding door.
Windows are usually given letters and the symbols are placed outside of the building adjacent to the window.
Each window type and size gets its own number. If a building has two windows exactly the same, its lettering is actually seen twice or the plan. Windows & lettered A – Z .(Figure 2)
Doors & rooms are numbered consecutively 1st floor rooms 101, 102 etc 2nd floor 201 202 etc.
Small rooms within large ones are given numbers as 101 – A.
Numbering begins at the main entrance and proceeds around the plan and back to the beginning.
Doors are frequently given the same number as the room 207, 207 – A.
Elevation symbols describe the basis features of the elevation, material used, style & position of doors & windows.
They also help to make the elevation look more relatives.
