2. Computer Aided Design or CAD for short, is the prises of designing object on computer before manufacturing or building

3. what type of people use CAD Architects & architectural Technicians Fashion Design Engineers Interior Designers Map Making and Cartography

4. Design:- The object you are trying to create CAD:– Translating it into the computer and planning what you want to build Controlling:- Directing the computers functions Manufacturing:-Building the object in the real world.

5. 3D- CAD Surface and Solid Modelling What are the deferent types of CAD? 2D – 2 Dimensional with X & Y coordinates, 2D- CAD A vector based drafting, good for simple constructions 3D – 3 Dimensional with X,Y, & Z coordinates, The U.C.S. Universal Coordinate system

6. This is the opening screen in CAD

7. This is typical view of a 2D Design on a CAD Screen

8. This is typical view of a Completed Design on a Paper

9. This is Plan View used in the Architectural and Building trade

10. This is an Elevation used in the Architectural and Building trade

11. This is a Section Through a building also used by architects and builders

12. CAD Designers Some times usese models Models are a 3D repersentation of an Object This is a tipical type of model

13. What are the benefits of crating a model? You can see if all the parts fit correctly You can tack as many a section views as you like

14. An example of a section through on a Model

15. A section through is like an inpretion of an object as if you have past a thin pain of glass through it and got an inprint of the area.

16. Another Useful feature of using model is creating an exploded view as seen above, that an Engineer would use for example in a manual.
