FUNDAMENTALS OF COMPUTER GRAPHICS
2 – marks question and answers
1. What does CAD CAM CAE stand for?
This chapter is concerned with CAD (computer-aided design), CAM (computer-aided manufacture) and
CAE (computer-aided engineering).
2. Is Solidworks a CAD or CAE?
SolidWorks (stylized as SOLIDWORKS) is a brand of software used for solid modeling computer-aided
design (CAD) and computer-aided engineering (CAE). It was one of the first 3D CAD applications
designed to run on a desktop PC.
3. What are computer graphics fundamentals?
Computer graphics is an art of drawing pictures, lines, charts, etc. using computers with the help of
programming. Computer graphics image is made up of number of pixels. Pixel is the smallest addressable
graphical unit represented on the computer screen.
4. What are the 7 basic elements of computer graphics?
Line, shape, form, texture, space, imagery, typography and color. Understanding each of these basic
, elements of graphic design in isolation will help you see how to bring them together and open a whole
world of creative possibilities.
5. What are the 7 steps in the design process?
Frame a Question: Define the Challenge. ...
Gather Inspiration: Research & Empathy in Action. ...
Synthesize for Action: Turn Research into Insights. ...
Generate Ideas: Expand Creative Possibilities. ...
Make Ideas Tangible: Rapid Prototypes. ...
Test to Learn: Refine Solutions Through Feedback.
6. What are CAD and its types?
CAD (Computer-Aided Design)CAD is a computer-based technology used for designing, analyzing, and
simulating products or systems. It enables users to create, modify, and optimize digital models of physical
objects or systems.
Types of CAD:1. 2D CAD (Two-Dimensional): Creates 2D drawings and models using lines, curves, and
shapes.
2. 3D CAD (Three-Dimensional): Creates 3D models and assemblies using various techniques (e.g.,
extrusion, sweeping, lofting).
3. Parametric CAD: Uses parameters and constraints to define and update models.
4. Direct Modeling CAD: Allows direct manipulation of 3D geometry without requiring a feature tree.
7. What are the 5 components of a CAD system?
1. Hardware: Computers, graphics workstations, or mobile devices with sufficient processing power,
memory, and graphics capabilities.
2. Software: CAD software applications (e.g., AutoCAD, SolidWorks, Fusion 360) that provide tools for
, creating, editing, and analyzing digital models.
3. User Interface: The graphical user interface (GUI) that allows users to interact with the CAD software,
access tools, and view models.
4. Data Management: Tools and systems for managing CAD data, including file storage, version control,
and collaboration features.
5. Peripherals: Input/output devices (e.g., mice, keyboards, graphics tablets, 3D printers) that facilitate
interaction with the CAD system.
8. What are the four applications of CAD?
1. Product design: Creating digital models of products.
2. Engineering analysis: Simulating performance, stress, and other factors.
3. Manufacturing: Generating manufacturing data and toolpaths.
CAD is widely used in various industries, including architecture, engineering, product design, and
manufacturing.
9. What is the principle of CAD?
1. Create: Design and model digital representations of objects or systems.
2. Modify: Edit and refine designs using various tools and techniques.
3. Analyze: Simulate and evaluate design performance, stress, and other factors.
4. Document: Generate technical drawings, documentation, and manufacturing data.
The core principle is to leverage computer power to enhance design productivity, accuracy, and
innovation.
10. What are a coordinate system and its types?
A coordinate system is a mathematical framework used to:
1. Locate points: Define positions in space using numbers (coordinates).
, 2. Describe geometry: Represent geometric shapes and objects.
Types of Coordinate Systems:1. Cartesian Coordinate System: Uses x, y, z axes (2D or 3D).
2. Polar Coordinate System: Uses radius and angle (2D).
3. Cylindrical Coordinate System: Combines polar and linear coordinates (3D).
4. Spherical Coordinate System: Uses radius and two angles (3D).
Coordinate systems are essential in various fields, including mathematics, physics, engineering, and
computer graphics.
