USES OF PARALINE DRAWINGS
Even though a paraline drawing always presents either
an aerial view or a worm's-eye view of a subject, we can
construct apara lineview in any of several ways to
reveal more than the exteriorform and configuration
of a design. These techniques allow us to gain visual
access to the interior of a spatial composition or the
hidden portions of acomplex construction. We
categorize these techniques into expanded views,
cutaway views. phantom views, and sequential views.
Expanded Views
To develop what we call an expanded or exploded
view. we merely shift portions of a para line drawing to
new positions in space. The finished drawing appears
to be an explosionfrozen at apoint in time when the
relationships between the parts of the whole are
most clear.
• Expanded views areextremely useful in describing
thedetails, layering, or sequence of a construction
assembly. Remember that, as with other drawing
types, the larger thescale of a para line drawing, the
more detail you have to show.
• At alarger scale, expanded views can effectively
illustrate vertical relationships in multistory
buildings as well as horizontal connections across
space.
