Answer 3

It allows you to draw various components that are then joined together on screen to give you an in depth analysis to what needs to be developed and designed.

Question 4

What are the main modelling and prototyping aspects used in CAD?

Answer 4

Block modelling - These are 3D models created from certain materials such as ABS and acrylic to make it look like the real thing

Rapid prototyping using CAD - this involves the creation of 3D objects using laser technology to solidify liquid plastic polymers or resins using stereilitiography.
