Heading

The development of 3D

modelling software enables

architects and design

engineers to create realistic

3D models of their designs.

Previously they would have

been built from clay, card or

polystyrene blocks.

A 3D computer model is a

virtual object which can be

rotated on screen and viewed

from any angle.

The wireframe

model is built

up using a

series of

connected

lines toproduce a 3D

object.

The surfacemodel is built

up by drawing

the surfaces ofan object. ike

adding the

canvass ontothe frame of a

tent.

The solid model isbuilt up by using

simple geometric

forms or e!trusions

" such as cuboids,cylinders # prisms.

These can be

added or

subtracted to

produce comple!

3D models.

&asily add colour # surface te!ture.

Test structural designs before building eg bridges

# skyscrapers.

&asily sent by email to remote locations

throughout the world.

ess storage space re%uired than a 'real( model.

)sed to create realistic simulations.

$lients can e!plore virtual 'walk through( of 3D

model designs.

Computer generated models are virtual and can

lack the feel of a traditional model which can

be picked up and handled.

Purchase cost of computers and software.

Training of staff in use of software.

Maintenance of IT systems & network servers.
