Technical drawing

Reading Look at three representations of a house. Name the types of drawing. Then read
the text and check your answers.

bedroom

here are many ways of putting a 3D object into 2D. Orthographic projections can
Tbe found on all construction projects. These drawings show different views of the
object, and can include elevations (a view from one side) and cross-sections (the view
when you cut through an object). Another type of drawing shows exploded views, which
are very useful for understanding the assembly of an object, in other words how it all fits
together. A third type of drawing is the plan view, which allows us to see an object from
above. A typical example of this is a floor plan. These are very useful when we want to
look at the fittings in detail, in other words where objects like cookers and baths go.

Speaking 2 Work in small groups. Discuss what other types of drawing are used in the
construction industry.

Vocabulary 3 Identify these 2D shapes in the drawings in 1. Write the names of the shapes on
the drawings.
