13.2 Analysis with 3D presentation
Presenting design in three dimensions is an important way to
look at engineering and urban design together. It enables street
furniture, lighting, utility equipment and landscape to be clearly
shown. Three dimensional layouts are also useful in consultation
with the public.
Street plans and cross-sections should be developed
initially. Simple perspectives or axonometric drawings can be
produced to add clarity and assist designers in visualising and
refining their ideas. Such three-dimensional representation is
fairly easy to achieve by CAD software or by hand.
Hand versions
have the advantage of being totally under the control of the designer.
Axonometric drawings are easily produced, using axonometric graph
paper. The dimensions indicated on a plan are transferred to the
30 degree angled lines. The drawing is thus to scale.
AXONOMETRIC PROJECTIONS
A simple junction
Plan of junction with key dimensions: A,
B, C, D, E
Axonometric of junction which can be used to position street
furniture and assess the designs visual impact.
Alternative designs may be visually compared with this simple
tool which is low tech and easily adjuctable.
Would the area benefit from having additional trees or some seating
for instance?
