CAD and Vector Graphics Questions

What is the primary purpose of a 3D model in graphic communication?

• To reduce the size of files for faster processing

• To create a flat image for printing purposes

• To store data for future reference

• To represent an object in three dimensions for visualisation

Which file type is best suited for high-quality photographs?

• JPEG

• GIF

• SVG

• BMP

What does the term 'vector graphics' refer to?

• Animated graphics for web use

• 3D models rendered in real-time

• Images made up of pixels

• Images created using mathematical equations

What is the main advantage of using 3D modelling software?

• Ability to create realistic representations of objects

• Easier to print documents

Which of the following is a disadvantage of raster images?

• They support transparency better than vector images

• They are generally smaller in file size

• They are easier to edit than vector images

• They can lose quality when resized

What is the purpose of a wireframe in modelling?

• To convert the model into a different file format

• To apply colours to the model

• To create a detailed texture for surfaces

• To outline the basic structure of a 3D object

What is a common use for a .STL file?

• 3D printing

• Web design

• Video editing

• Image compression

When there are more pixels an image is better quality

• True

• False

A Raster image is made up of pixels

• True

• False

The main advantage of a raster graphic is...

• Images do not become pixelated when resized

• It can be opened up and edited in common software

• They are good for high quality prints
