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.
