AUTO-CAD INTERFACE.....

Produced very quickly.modified very easily.Easily add colour & surface

texture.Test structural designs

before building eg: bridges & skyscrapers.

Easily sent by emailLess storage space required

than a ‘real’ model.Create realistic simulations.Clients can explore virtual

‘walk through’ of 3D model designs.

ADVANTAGES

Lack the feel of a traditional model.

Cost of computers and software.

Training of staff in use of software.

Maintenance of IT systems & network servers.

DISADVANTAGES....

PARAMETRIC MODELING

Introduction to Solid Modeling

3D COMPUTER MODELS......

Development of 3D modelling software enables architects

Create realistic 3D models of their designs

FEA...

How do you control color and appearance.

Assign Materials. Assign Shaders. Assign Textures. Advanced Shaders – eg Renderman.
