4. Why WE need CAD packages?
1. Create Conceptual product models with Aesthetic
appearance with high performance .
2. For viewing object in different angle
3. To preparing detailing for manufacturing with
Dimensions, Tolerance with surface finishing
4. Analysing
5. Storing Database of drawing for future use
6. Presentation and High Productivity

5. Define CAD?
- Computer Aided Design
What is mean by Design?
- It is the perception of an
object to Create, Modify &
Analysis of the object

6. Types Of Designs
There are THREE types of design, they
are as follows:-
* Adaptive Design
* Developed Design
* Newly Design

7. Adaptive Design
In this type of design we will create the
object or component without any modification
in its shapes & sizes
Examples : Railway Tracks, Chalk Pieces.

8. Developed Design
In this type of design we will create the
object or component with some modification
in its shapes & sizes but same usages
Examples : Vehicles, Mobiles, Etc.,

9. Newly Design
In this types of design we will create a new
object or component without from the
existing models
Examples : 7Wonders, ATM, Pooling Machine

10. Design Cycle Process
There are two types of design cycles
they are as follows,
*Design Cycle - by Manual Process
*Design Cycle - by CAD Process

11. Design Cycle Process By Using Manual Method
Identification of needs
Definition of problems
Synthesis (way of ideas)
Analyzing
No
Yes
Manufacturing
Marketing
Feed backs

12. Design Cycle Process By Using CAD
Drafting
Modeling
Analyzing
No
Yes

Feed backs

13. Drafting
 The systematic representation and dimensional
specification of mechanical and
architectural structures.
Used to create 2d drawings
Basic thing to manufacture the components
Can understand only by technical peoples

16. Drafting Softwares
AutoCAD

17. Modeling
 Used to create realistic views
Easy to understand for all
Advanced real features
Operations of the model

20. Mechanical Modeling Soft wares
Creo Elements
Catia
Unigraphics
Solid works

21. Analysis
Computer based numerical Technique for
calculating the strength and behavior of
engineering structures/elements.
The Technique has very wide application and
has been used on problems involving Stress
analysis, Fluid analysis, Fluid mechanics, heat
transfer, vibration, electrical and magnetic field
etc.,

22. Mechanical Analyzing Software
Ansys

25. PPM
Project management is the discipline
of planning, organizing, motivating, and
controlling resources to achieve specific
goals
initiation
planning and design
execution and construction
monitoring and controlling systems
completion

26. PPM Soft wares
MS Project
2010
Primavera
P6

27. Advantages of CAD
*Cost is less (labour, machine & material )
*High Accuracy
*Time consumption is less
*Modification is easy
*Useful for future references

28. Applications of CAD
*Space Centers
*Research & Development
*Mechanical Industries
*Civil Constructions
*Electrical Equipments
*Textile Industries
