• Entertainment, media and advertising

• Fashion, culinary and textile design

• Architecture, automotive and industrial design

• Medical, pharmaceutical and chemical industries

What is an advantage of creating 2D CAD drawings over 3D CAD?

• Lighting effects can be applied to 3D models

• Can be simulated and animated

• No multiple components to assemble

• Models can be manipulated to be viewed around 360 degrees

What is a benefit of using a CAD library?

• It saves both time and effort

• It increases the cost of the project

• It makes the drawings less accurate

• It complicates the design process

What is a modelling tree?

• A method of applying textures to a CAD model

• A type of 3D CAD model

• A hierarchal list that shows how you have created your CAD model

• A list of materials used in a CAD model

What is an advantage of 3D CAD modelling?

• There is no depth to produce

• Models can be manipulated to be viewed around 360 degrees

• Fewer steps required

• No multiple components to assemble

What is 3D CAD Illustration?

• The process of creating orthographic views

• The process of assembling multiple parts in a CAD model

• The process of applying materials, highlights and shadows to a CAD model

• The process of creating 2D technical drawings

What is an advantage of 3D CAD Illustration?

• It allows the designer to apply materials, textures, light sources, shadows and reflections to graphics

• It makes it harder for non-graphics specialists to understand

• It hides the materials used

• It makes the models look less realistic

What is the purpose of orthographic views in CAD?

• To apply lighting effects

• To store common drawing parts

• To create 3D models

• To communicate between designers and manufacturers

What is a potential issue with using CAD software?

• It is always free to use

• It has no security risks

• It can have high costs of both the hardware and specialist software

• It never crashes

Why is selecting materials important in CAD illustrations?

• To reduce the rendering time

• To make the model less detailed

• To increase the file size

• To make renders look life like and realistic
