3.4 CAD

Is a model that determines the structure of data. 

• Prototype

• Data modelling

• Graph

• Haptic technology

Haptic Technologies

• Create a virtual environment where the user can interact with it in a realistic way.

• Can be used to simulate a process

• Use the sense of touch to provide feedback to the user.

• Can only perform movements that are anatomically possible.

The calculation and simulation of unknown factors in products using CAD systems calls

are clear representations of the final part. They provide a complete set of data for the product to be realized.

• Solid models

• Surface models

• Digital humans

• 3D

help to predict how a human (real) will react in a variety of situation or environments (places or locations)​

• Virtual reality

• Digital human

• Motion capture

• Haptic technology

Design begins with criteria and parameters and is then developed as concept.

New features and parts are added as the design evolves.

The final design is a collection of inter-related parts that are uniquely design.
