Is a parametric modelling tool developed by Dassault Systemes which was started somewhere
in 1980’s
Dassault systems first developed a 3d designing tool called Catti.
They made tie up IBM and later on it was called Catia.
V1, V2, V3, V4, V5, V5 are the versions fo Catia, V1,V2 used from 1983-87, V3 developed
in 1988, V4 developed in 1994, V5 developed in 1998 and V6 developed in 2008.
V1, V2, V3 used to work on mainframes, V4 works on unix operating systems, V5 works on
both unix and windows operating systems.
Kernel for Catia V5 is CNEXT
There are around 175 modules in catia v5
Catia V5 is extensively used in manufacturing of Automotive, Aerospace, Locomotive,
Industrial, Medical components
We use six modules in catia:
1.

PART MODELLING
Start → Mechanical Design → Part Design
File extension is CAT PART
Tool Bars used in Part:
1. Sketch based features
2. Dress up features
3. Transformation features
4. Reference elements
5. Boolean operations
6. Surface based features
1. Sketch Based Features:
In part modelling sketch should be iso-constraint & fully closed. The sketch should not be
self intersect.
Pad: It adds material normal to the profile. If we select thick option, we get hollow part with
some thickness. If we select mirror, material will be added on both sides.
If we check out normal to profile then we have to select a line at any angle. Thus material
will be added in that direction. See below fig.
Jamescadcam@gmail.com (9703093064)

Multi-Pad: If there are different profiles in one sketch & if we want to add material in
different dimensions we have to select each profile and give dimension individually.
Pocket: It removes material normal to the profile.
Shaft: It adds material by rotating along axis. If the sketch is open, we have to select
thickness. If we take an axis then it will be automatically selected.
Groove: It removes material by rotating along an axis.
Hole: we can create different types of holes like counter bore, counter sunk, tapered, threaded
etc. We have to select a point on the surface. We have to see threaded holes in drafting.

Rib: It requires a profile & a centre curve. It adds material by passing through the curve.
Select the profile & select centre curve, if we select thick we get hollow section. The profile
may be at any distance from the curve.
Slot: It is opposite to rib. It removes material by passing through a centre curve.
Jamescadcam@gmail.com (9703093064)
Page 13
Material on CATIA V5
Stiffener: to create ribs to the part. It gives stiffness to the part.
Solid Combine: It combines two different profiles which are perpendicular to each other.
Multi-section Solid: It adds material for different profiles. Select two profiles , right click on
closing point, select remove and go to selected sketch, right click, select create closing point
and keep the point collinear to the other closing point. If profiles are same section, select
tangency than curvature, if profiles are different then select ratio in coupling option. If
profiles have vertices select coupling and select vertex points. The material will be added
between these couplings. If we select spine the material will be added by curvature. In
relimitations if we checkout, the material will be added from starting to end point of spine. In
guides we have to create separate lines between two profiles. Guides should connect to the
profile.
We can use both couplings and spline as showin in fig.
Some times we can use both guides and splines as showin fig.
Guides should unsect properties but spline no need to connect.

If we select define parting element select a plane at the middle of rectangular block then the
face will be drafted up to that plane.
If the same plane is selected as neutral element and by selecting parting = neutral then we get
a draft angle from the middle plane to any one side.
If we select draft both sides both the sides will be given draft angle. In limiting elements
select 2 planes which are perpendicular to drafted face then we get a draft angle in between
the planes or apart from planes.
Variable Draft Angle: Select a face to draft & give different draft angle. Select point and
create number of points on edge & give individual draft angles.

There are two types of assemblies:
Bottom up assembly: In this we create parts in part modelling and saving it different folder.
We get all parts in assembly work bench where it is assembled.
Used for large assemblies.
Top down assembly: In this we create all parts in assembly work bench and we assemble in
the same work bench.
Used for assembling of small and precession parts.
Start → Mechanical Design → Assembly Design
File extension is CAT PRODUCT

Angle: select surface or edge or planes of two parts and give angle between them.
Fix together: select the tool and select two or more parts. If we move them all parts will
move together.
Quick constraint: select surface or edge or plane; by default coincidence or contact or offset
constraints will be applied.
Change constraint: used to change already applied constraint; select the tool select
constraint which we have to change and apply suitable constraint.
Reuse pattern: If a part to be assembled in rectangular or circular pattern then select the tool,
select the part and select cylindrical surface of hole. If we select generate constraint all
constraints applied to the part will also generated on all instances. These types of constraints
are used when a plate is assembled with number of bolts.
Existing component with positioning: while getting a part into assembly work bench a
separate window will open so that we can move the part where we require and also we can
apply constraint by selecting constraint option in it.
Replace Component: used to replace component; select the tool and select component which
we want to replace.
Graph tree reordering: to reorder sequence of parts in specification tree.

Generate Numbering: It generates numbers to all parts in assembly. It is seen in drafting work
bench.
Manage representation:
Select any part in specification tree select shape and select deactivate then you can see the
part in specifiation tree but you can’t see any feature in the part.
Fast Multi Instantiation: if any part has to be used frequently then select the tool give
instances and direction. It has to be constrained.
3. Move:
Manipulation: used to move part in all degrees of freedom
Snap: used to move parts, select the tool select surface or edge or axis. We can also reverse
the part by a click on green arrow.
Smart Move: by this tool not only we can move part but also we can constrain it.
Explode: to see all parts in an assembly. Parts will disassembled by this tool. When we
update it again get assembled.
Stop manipulation on clash: if we select this tool we can’t move large shaft into small hole
as there is clash between parts.
4. Scenes
Enhanced Scene: to get exploded view in drafting we use enhanced scenes.
Create assembly → enhanced scene → naming → full → explode → ok → exit scene →
open drawing → front view or isometric view → go to assembly → open application in
specification tree → select scene → select plane or surface.
Scene browser: if we create more scenes then we can see all scenes in separate window.

5. Space Analysis
Clash: used to see contact and clash between parts in assembly. Select the tool select all parts
individually. This can be seen in application in specification tree.
Sectioning: used to see different sections between parts in an assembly. Sectioning can be
done by plane or box or slice. This can be seen in application in specification tree.
Editing in assembly:
If any modifications have to be done on a particular part then double click on part it will go to
part modelling edit there once it is finished double click on product.
When we apply constrains in assembly instead of updating manually, we can update
automatically by tools → options → mechanical design → assembly → general → automatic
Top down assembly:
Select part in product structure tool bar then select product in assembly. Part1 is generated
then open part1 double click on part. Part modelling work bench will open create a part in
this and double click on product. Assemble parts by using constraints.
