3. What is CAD?

4. "Computer-aided design (CAD) is the use of
computer systems (or workstations) to aid
in the creation, modification, analysis,
optimization and manufacturing of design
or physical objects.”

5. Now! Let’s take
a look at

6. The History of
CAD

7. - The Beginning
In 1960, Ivan Sutherland MIT's Lincoln Laboratory created
SKETCHPAD, A Man-Machine Graphical Communication System.”
which uses a light pen to manipulate objects displayed on
a CRT Display.
Concept of CAD started when Dr. Patrick J. Hanratty
developed PRONTO (Program for Numerical Tooling
Operations)
PRONTO was the first commercial CNC programming system.
1957
- The Sketchpad1960

8. 1960 Ended with many companies commercializing CAD
programs and formal development of Computer Aided
Designing software started.
- Digitizers
For better human computer interaction digitizers started
to appear and many industries jumped in the business.
Notable Digitizers of that time are:
1. Auto-troll
2. DAC-1
1960
- End1960

9. Major milestones included the work of Ken
Versprille, whose invention of NURBS for his
Ph.D. thesis formed the basis of modern 3D
curve and surface modeling, and the
development by Alan Grayer, Charles Lang, and
Ian Braid of the PADL (Part and Assembly
Description Language) solid modeler.
- The NURBS1970

10. Emergence of UNIX workstations appeared and
commercial CAD systems like CATIA and others
began showing up in aerospace, automotive,
and other industries.

1980 -

11. - AutoCAD1983
A group of programmers formed Autodesk, which
in 1983 released AutoCAD, AutoCAD was the
first significant CAD program for the IBM PC.
AutoCAD marked a huge milestone in the
evolution of CAD

12. CAD systems changed in 1987 with the release
of Pro/ENGINEER, and other CAD program based
on solid geometry and feature-based parametric
techniques for defining parts and assemblies,
that was game changer.

13. The modern CAD era has been marked by
improvements in modeling, incorporation of
analysis, and management of the products we
create, from conception and engineering to
manufacturing, sales, and maintenance (what
has become known as PLM, product lifecycle
management).
- Modern CAD Era1990

14. Now The
Question is
What’s wrong with
traditional methods?
Let’s see....
What is the use of CAD

15. Applications of CAD

us explore ideas,
visualize concepts
Easily and effectively which
promotes innovation and
creation of new ideas

17. Increases the
productivity of the
designer

and precision of
design
Quality and precision of
designing can vastly improved
by use of computer aid

19. Improve
communications in
designing process
CAD provides ways to improve
communication through detailed
drawing and documentation

20. CAD drawings convey
information required for
production of design
Like; materials, processes, dimensions
and tolerances according to specific
conventions

21. Simulating Real World
operations and realistic
rendering
how the design project will perform
in the real world scenarios.

22. Analyzing real
world scenarios by
Computer Aided
Analysis
like
Finite Element Analysis
Multibody Dynamics and
Computational Fluid Dynamics

23. Creating a
database for
manufacturing of
products
Database of CAD models can be
created to assist and ease the
product development and designing

24. Expanding Horizons
of possibilities
CAD may be used to design curves
and figures or curves, surfaces and
solids ever imaginable

25. Introduction to
CATIA

26. CATIA (Computer Aided
Three-Dimensional
Interactive Application)

27. CATIA is a multi-platform software
suite for
 Computer Aided Design (CAD)
 Computer Aided Manufacturing (CAM)
 Computer Aided Engineering (CAE)
 PLM
CATIA is developed by the French company Dassault Systèmes.

28. The History of
CATIA

29. - Birth of CATIA
In 1984, the Boeing Company chose CATIA V3 as its
main 3D CAD tool, becoming its largest customer.
CATIA started as an in-house development in 1977
by French aircraft manufacturer Avions Marcel
Dassault, at that time customer of the CADAM
software to develop Dassault's Mirage fighter jet.
1977
- Growing up1984

30. - The Transition
In 1992, CADAM was purchased from IBM, and the
next year CATIA CADAM V4 was published.
In 1988, CATIA V3 was ported from mainframe
computers to Unix.
1988
- The V4 Release1992

31. - Retransition
In 1998, V5 was released and was an entirely
rewritten version of CATIA with support for UNIX,
Windows NT and Windows XP (since 2001).
In 1996, it was ported from one to four Unix
operating systems, including IBM AIX, Silicon
Graphics IRIX, Sun Microsystems SunOS, and Hewlett-
Packard HP-UX.
1996
- The V5 Release1998

32. - New Era and V6
Dassault Systèmes launched CATIA V6-R2011x, the
latest release of its PLM2.0 platform, while
continuing to support and improve its CATIA V5
software.
Dassault Systèmes released CATIA V6. While the
server can run on Microsoft Windows, Linux or AIX,
client support for any operating system other than
Microsoft Windows was dropped.
2008
- Adoption of PLM2010

33. - Release of R2012
Dassault Systèmes launched V6 2013x with major
database and PLM improvements.
Dassault Systèmes launched V6 R2012.
2011
- Release of R20132012
Dassault Systèmes launched 3D-EXPERIENCE
Platform R2014x and CATIA on the Cloud, a
cloud version of its software.

34. Applications of
CATIA

35. CATIA enables the creation of 3D parts, from
3D sketches, sheet metal, composites, molded,
forged or tooling parts up to the definition
of mechanical assemblies. The software
provides advanced technologies for mechanical
surfacing & BIW. It provides tools to complete
product definition, including functional
tolerances as well as kinematics definition.

36. CATIA offers a solution to shape design,
styling, surfacing workflow and visualization
to create, modify, and validate complex
innovative shapes from industrial design to
Class-A surfacing with the ICEM surfacing
technologies. CATIA supports multiple stages
of product design whether started from
scratch or from 2D sketches.

design and manufacturing of electrical
systems spanning the complete process from
conceptual design through to manufacturing.
Capabilities include requirements capture,
electrical schematic definition, interactive
3D routing of both wire harnesses and
industrial cable solutions.

delivers a unique open and extensible systems
engineering development platform that fully
integrates the cross-discipline modeling,
simulation, verification and business process
support needed for developing complex ‘cyber-
physical’ products. CATIA has capabilities of
both Dynamic Behavior Modeling and simulate
the behavior of complex systems.

Equipment industry. Industrial Manufacturing
machinery companies like Schuler and Metso use
CATIA, as do heavy mobile machinery and
equipment companies like Claas, and also
various industrial equipment product
companies.

Industrial Applications

42. Comparison of
CATIA with Others

43. CATIA is a huge application, with so many
functions and abilities, it can handle huge
projects, like rockets , engineering design
and manufacturing while AutoCAD is widely
used for civil and architectural
engineering, mostly for very large drawing
scale, like structures and buildings.
CATIA vs. AUTOCAD

44. 1. SolidWorks is good for machine design while
CATIA is great for generating shape design
and has a advanced surface modeling tools.
2. Catia is good at finishing the small parts
faster than Solidworks.
3. Catia is complicated while Solidworks
simple, it is for professional usage and
Catia is for industrial level use.
CATIA vs. SOLIDWORKS

45. Solidedge is direct competitor of
other in mid level CAD market and is
cost and effective while CATIA is a
top end CAD used mainly in industries
like the aerospace and the car
industry.
CATIA vs. SOLIDEDGE

46. Pro-E is a competitor of CATIA in many
aspects of CAD and they are similar in
cost and capability. CATIA is a top end
CAD used mainly in the aerospace and the
car industry while Pro-E is mainly used in
mechatronic product and appliances and
tool designing.
CATIA vs. PRO-E:

47. When it comes to industry level designing
CATIA comes in competition with
Unigraphics NX. CATIA is especially known
for its Surface Designing capabilities
and large scale assemblies while NX CAD
is especially used for 3d-modelling.
