1. Literacy Focused Task C.A.D
Computer Aided Design

2. Communication Problem Solving
LESSON OBJECTIVES
Develop your understanding of Computer Aided Design.
Develop your Oracy and Literacy skills.
Key Skills
Communication Problem Solving

3. CAD Theory Computer Aided Design
What Does C.A.D stand for?
Computer Aided Design
C.A.D is the designing of products using a computer, rather than drawing ideas on paper.
Examples of C.A.D programs?
2D Design
Auto CAD
2D Programmes
Google Sketch Up
Pro Desktop
Solid Works
3D Programmes

4. CAD (Computer Aided Design
What are the advantages of C.A.D
Accurate.
Quicker.
Easier to compare/modify/develop designs easily, quickly and cheaply.
Problems can be solved using CAD before you make a prototype to avoid any expensive mistakes.
Products can be viewed from all angles, and the size of parts can be worked out in relation to other parts.
Easily shared.
CAD drawings can be manufactured using Computer-Aided Manufacture (CAM) or Computer Numerical Controlled (CNC). B

5. CAD (Computer Aided Design
How can C.A.D be used to suit the customers needs?
1) CAD images can be changed in a number of ways.
2) You can edit the, colour, material. construction, dimensions (size) of the final product.
3) This allows your customer to have a full understanding of your design and it allows your customer to change the design quickly and easily before manufacture. B

6. CAD (Computer Aided Design
What are the Disadvantages of C.A.D
Expensive to set up i.e. The computer and the computer programs.
CAD programs are often difficult to use and can take a long time to learn.
Computer viruses, corrupt files, not saving work and power cuts can often lead to loss of work.

8. Shared Reading
Task 1. – Before completing the shared reading task read through the information on the board and practice any words you may find difficult..
Task Rules
Read the information given to you by your teacher in silence for 1 minute.

9. Shared Reading Short Extract
Computer-Aided Design involves designing products on a computer, rather than the traditional methods on paper. Software ranges from 2D engineering drawing programs in 3D frame and solid modelling.
CAD allows designers to model and compare designs cheaply and relatively easily. Also, many problems can be ironed out before the production of prototypes.
In 3D programs, finished products can be viewed from all angles, and scales of components can be worked out in relation to each other.

10. Shared Reading Golden Rules
Your Teacher will lead the task.
No voice louder or faster than the teacher’s.
No silly voices
