5.5 Plans and elevations
You can use isometric paper to make accurate drawings of three-dimensional shapes.
Another way of drawing or describing three-dimensional shapes is to use plans and elevations.
!ese can be drawn on squared paper.
Plans and elevations show what a shape looks like from di&erent directions.
An example will make this clear.
!is shape is drawn on isometric paper.
A
A plan is the view from overhead, in the direction marked A.
An elevation is the view from the front (from direction B) or D
from the sides (directions C and D) or from the back.
Here is the plan.
C

Plan view from A
!e lines show where you would see an edge, looking from above.
!e column that is three units high in the isometric drawing is shown as a square in the top right-hand
corner of the plan.
!e column that is two units high on the le# of the isometric drawing is show as a square in the bottom
le#-hand corner of the plan.
Here are three elevations of the same shape.
You can see the columns that are two units high and three units high in each elevation.
Elevation from B Elevation from C Elevation from D
