An introduction to CAD & 3D modelling

Design and technology

Use of equipment that may require supervision for safety, eg. scissors, needles, paint, knives

A car company would use all these modelling methods, but which would be the last stage?

You will need to be trained to use specialist programmes.

Can be time consuming and difficult to make.

Cardboard can be easily sourced and cheap.

Often can't be tested as they do not use the same materials as the final object.

What are the advantages of 3D modelling? (Tick 2 boxes)

A working model of a product made for testing is called what?

You can make it to size or scale it up and down.

You can only see one side of the product.

You can understand how the components work together.

Which is not an advantage of 3D modelling?

Which industries model their product before manufacture?
