CAD Surface Modeling

Question 1

In Computer-Aided Design, what are the fundamental principles of surface modeling?

Accepted Answer

Balance, contrast, emphasis, movement, pattern, rhythm, and unity

Answer

Only color and size considerations

Answer

Speed of completion and cost efficiency

Answer

Using as many elements as possible

Question 2

What is the purpose of a wireframe in Computer-Aided Design surface modeling?

Accepted Answer

To create a simplified visual guide showing the structure and layout of a design

Answer

To produce a final, polished design ready for production

Answer

To write the technical code for implementation

Answer

To test the physical durability of materials

Question 3

In Computer-Aided Design, what does "resolution" refer to in digital design?

Accepted Answer

The number of pixels per unit of measurement, determining image clarity

Answer

The file format used for saving images

Answer

The color scheme of a design

Answer

The physical size of the printed output

Question 4

What is the purpose of layers in Computer-Aided Design surface modeling software?

Accepted Answer

To organize different elements independently so they can be edited without affecting others

Answer

To increase the file size of the project

Answer

To limit the number of colors available

Answer

To prevent any changes to the design

Question 5

In Computer-Aided Design, what is the rule of thirds?

Accepted Answer

A compositional guideline that divides the frame into a 3x3 grid for balanced placement

Answer

A rule requiring exactly three elements in every design

Answer

A requirement to use only three colors

Answer

A guideline for working in three-hour sessions

Question 6

What is the difference between raster and vector graphics in Computer-Aided Design?

Accepted Answer

Raster uses pixels and loses quality when scaled; vector uses mathematical paths and scales infinitely

Answer

Raster is always better quality than vector

Answer

Vector graphics cannot display colors

Answer

There is no practical difference between them
