AIM
To study the basic features of CATIA.
THEORY
CATIA (Computer Aided Three-dimensional Interactive Application) is a multi-platform
CAD/CAM/CAE. It is written in the C++ programming language. CATIA supports multiple
stages of product development (CAx), from conceptualization, design (CAD), manufacturing
(CAM), and engineering (CAE). CATIA can be customized via application programming
interfaces (API). CATIA V5 can be adapted via the Visual Basic and C++ programming
languages, an API called CAA2 or CAA V5 (Component Application Architecture) that is a
component object model (COM)-like interface.
Features of CATIA Design Software
 Optimal Sharing
Catia users will get access to a unique, collaborative 3 dimensional environments that
can be access by an unlimited number of people online. This allows people from across
the globe to collaborate in a virtual environment. It has been designed to not only allow
for online cooperation, but also makes offline sharing and designing easy to integrate
as well.
 Simplified Product Development
Creating a new product can be a long and complex process. It encompasses multiple
design phases including the initial design, overall development, and manufacturing.
Catia decreases the complexity and length of the entire project because it integrates
various stages of the development process so that they can be controlled and modified
on a single platform.
 Seamless Transitioning
Every version of the Catia design software is designed to allow for seamless integration
with previous versions. This makes upgrading a simple process and can be completed
without losing any of the information that has already been stored.
CATIA Modules
CATIA consists of several modules and each module is specialized in specific design field

4. V i s h a l S i n g h ( 0 0 3 2 0 9 0 3 6 1 3 ) | 2
 Sketcher
This module is responsible for the implementation of two-dimensional shapes, in
preparation for a three-dimensional command on it.
 Part Design
This module is responsible for converting two-dimensional graphics to three-
dimensional objects which is most famous in Catia and is closely linked with sketcher
module.
 Assembly
This module is responsible for assembling the parts previously produced in Part Design
 Stress Analysis
This module is responsible for testing parts designed to withstand the loads expected
occurrence on it, and shows how the mechanical parts are affected by the colours.
 Drafting
This module is responsible, for converting what is seen on the screen to standard
engineering drawings can be traded in the workshop for manufacturing or save them
for documentation.
 Surface and Wireframe
With this module surfaces can be drawing with zero size and weight and has its uses
in the aerospace, automotive, ships and mold Design.
 Simulation
This module is responsible for obtaining a similar movement of the natural movement,
which is expected to occur during the actual operation of the machine or mechanical
establishment whatever.
Modules of CATIA v5

5. V i s h a l S i n g h ( 0 0 3 2 0 9 0 3 6 1 3 ) | 3
Other modules include Sheet Metals, Mold Design, Welding etc. in mechanical design field.
Similar modules are available for different operations in infrastructure, machining, ergonomics
etc.
Toolbars
A set of tools that helps you create and constrain 2D geometries. Features (pads, pockets,
shafts, etc...) may then be created solids or modifications to solids using these 2D profiles.
The Sketcher workbench contains the following standard workbench specific toolbars.
 Profile toolbar
The commands located in this toolbar allows to create simple geometries (rectangle,
circle, line, etc...) and more complex geometries (profile, spline, etc...).
 Operation toolbar
Once a profile has been created, it can be modified using commands such as trim,
mirror, chamfer, and other commands located in the Operation toolbar.
 Constraint toolbar
Profiles may be constrained with dimensional (distances, angles, etc...) or geometrical
(tangent, parallel, etc...) constraints using the commands located in the Constraint
toolbar.
 Sketch tools toolbar
The commands in this toolbar allows to work in different modes which make sketching
easier.
 User Selection Filter toolbar
Allows to activate different selection filters.
 Visualization toolbar

6. V i s h a l S i n g h ( 0 0 3 2 0 9 0 3 6 1 3 ) | 4
Allows to, among other things to cut the part by the sketch plane and choose lighting
effects and other factors that influence how the part is visualized.
 Tools toolbar
Allows to, among others other things, to analyse a sketch for problems, and create a
datum.
RESULT
The basic features of CATIA V5 had been studied successfully.
