2. Introduction to
CAD
• CAD (Computer Aided
Design) is the use of computer
software to design and
document a product’s design
process.
• Engineering drawing entails
the use of graphical symbols
such as points, lines, curves,
planes and
shapes. Essentially, it gives
detailed description about any
component in a graphical form.

Engineer’s productivity
• Improve record keeping
through better
documentation and
communication

5. Types of CAD
Software

against the PowerShape CAD
data with PowerInspect. Inspect
parts on the shop floor, in the
inspection room or integrate
inspection routines on the
machine tool.

16. CAD/CAM for production machining
Feature recognition
Get feature recognition tools to
scan, identify and
automatically create
machinable features from your
design with associative
operations, reducing
programming time.
Multitask machining
Optimise CNC
programs (US site) for
multitasking turn-mills
capable of performing both
turning and milling
operations in a single
setup, helping reduce cycle
Swiss-type lathes
Focused Swiss machining
strategies for precision
manufacturing give you full
control over your Swiss-
type lathes based on your
tooling, machine tool and
volume of production.

18. Creo
• Creo CAD software is one of
the market leaders in product
design, developed by Parametric
Technology Corporation more
than 30 years ago. It integrates
many functionalities such as
thermal, structural, motion,
parametric and freestyle surface
generation and direct modeling.

19. Fusion
360°
Fusion 360

20. Solidworks
• Published by Dassault
Systèmes, it is often used by
professional 3D designers. It is
a parametric featured-based
model. The software includes a
wide range of features such as
design validation tools, or
reverse engineering. It tends to
be used for industrial objects.

21. AutoCAD
• AutoCAD software from
Autodesk was one of the first
CAD software to be released on
the market in 1982, making it a
very established CAD software
across industries. Even though
AutoCAD is popular and widely
used, in the 3D printing
community i

22. CATIA
• The CATIA CAD solution has
historically been developed for
Dassault Aviation’s own needs.
It is more than a simple CAD
Software, as it is also a multi-
platform software suite for
CAD, CAM (Computer Aided
Manufacturing), CAE
(Computer Aided Engineering)
and more.

23. Rhino
• the world’s most versatile 3D-
modeler. It is a commercial 3D
computer graphics and CAD software.
The program uses a precise and
mathematical model known as NURB
which allows to manipulate points,
curves, meshes, surfaces, solids and
more in all sorts of ways. Rhino3D’s
strong point is its wide range of
design features. It

24. Unigraphics /
Siemens NX
• The best notable feature
with Simens NX is that it has
the best product life cycle
management (PLM). Mostly
used for electromechanical
designs and mechatronics
design.

26. AUTOCAD
for Drafting
• AUTOCAD is one of the basic
software for drafting and

software usage in almost all
structural design consultancies
and firms especially in India.
AUTOCAD 3D version is also
available for 3D Modelling.

27. STAAD PRO for Design
and Analysis
• Bentley System's STAAD PRO is one such software
which is opted by many professionals in construction
field.
• STAAD.Pro is the structural engineering
professional’s choice for steel, concrete, timber,
aluminum, and cold-formed steel design of virtually any
structure including culverts, petrochemical plants,
tunnels, bridges, piles, and much more through its
flexible modeling environment, advanced features, and
fluent data collaboration.
