CATIA V5 Interview questions – Interview Questions for mechanical engineer on CATIA V5 – CATIA V5 Questions with Answers


1)            Expand CATIAV5?

Computer Aided Three Dimensional Interactive Application.

CAT Part

3)            Does CATIA V5 work on UNIX Platform?


4)            Is it possible to increase the size of plane boundary representation & how?

Yes, go for Tools-Options- Infrastructure-Part structure-Display

5)            Is It Possible to directly enter in to Sketcher Workbench?

No, it is not possible to enter in to sketcher workbench directly. We have to go for any

workbench &form there we can enter the sketcher workbench..

6)            Which is the tool used to exit from sketcher workbench to part design Workbench?

Exit Sketcher.

7)            What is use of construction elements?

Construction elements assist in sketching the required profile in sketcher.

8)            What are the default units of LMT (Length, Mass and Time)

mm, Kg, Second.

9)            What is SKETCH TOOLS in sketcher work bench & Explain the Importantance of it?

SKETCH TOOLS in sketcher workbench are the commands, which find very use in creating sketches.  SKETCH TOOLS are namely geometric and dimensional constraints, construction elements/standard elements and Grid option.  They play very important role in sketching, whenever we want to constrain a sketch we use these options and if we want to convert any element into a construction element once again these options come into picture.

10)        Is it possible to hide specification tree?                                                                                                                           

Yes, with help of F3 button, but the option in Tools command must be checked to

allow this.

11)        What is SHOW/HIDE option?

Show mode enable us to see all the components presently opened and in Hide mode we can

hide the desired elements from the view for time being.

12)        What is the use of Cut Part by Sketch Plane?

This task shows how to make some edges visible.  In other words, we are going to

simplify the sketch plane by hiding the portion of the material that is not needed for


13)        How do you measure arc length?

We can measure arc length by using MEASURE ITEM command.  Sometimes we need to

customize the option for arc length if it is not checked earlier using customization in


14)        What is the meaning of true dimension?

True dimension is the dimension desired after the machining. In other words, this is the

value that should be attained after the machining.


15)        What do you mean by ISO-Constraints?

If all of the degrees of freedom of geometry have been takes up by a consistent combination

of dimensions & fixed geometry,. That geometry is said to be ISO-CONSTRAINED.

Geometry that still has some degrees of freedom is said to be UNDER constrained.

16) Mention the color code of ISO-constrained, under, and over con strained elements?

The color code for these elements is Green, White and Magenta respectively.

17)  What for animated constraint command is used?

This task shows how constrained sketched element reacts when we decide to vary one


18)  How many dimensions are required to constrain the ellipse?

Three dimensions are required namely major axis, minor axis and the distance from the


19)  What are different conic sections?

Ellipse, Hyperbola and Parabola

20)  What is RHO value for ellipse, Parabola and hyperbola?

Parabola has RHO values of 0.5, Ellipse has RHO value between 0 & 0.5 and Hyperbola

has RHO value b/w 0.5 & 1.0.

21)  What is NURBS?

Nurbs are the type of curves

22)  How many types of Co-ordinate systems are there?

Three namely Cartesian, Polar and Spherical co-ordinate system.

23)  What are project 3D silhouette edges?

Project 3D silhouette edges in sketcher will shows how to create silhouette edges to be used

in as geometry or reference elements.

24)  What is use of sketch analysis?

To check whether the sketch is fully closed or not so that the sketch can be used or not so

that the sketch can be used for further operations in part design.

25)  Where do we use axis?

Axis is used in creating shaft (revolved) feature.

26)   Can we redefine the sketches?


27)  Can axis be converted into line or vice versa?

We can convert line into axis but axis cannot convert into line.

28)  How many axis can be created in a single sketch?

Only one axis can be created in a sketch, if more than one axis are drawn then only one of

them, the latest one, will be axis and others will be converted into reference elements.

29)  How do we change, sketch’s reference plane?

Right click on the sketch whose reference plane is to be changed and select the change

reference plane and then select new reference.

30)  What is the function of mirror command in sketch?

Mirror command in sketch will create a copy of the sketch about a reference plane.

31)  If I donor want the relation b/w original and mirrored elements what should I do?

Explore and the relation b/w the original and mirror element doesn’t exit.

32)  What is the use of isolate in sketcher workbench?

Isolated is used when 3D geometry is projected on to a sketch in order to be modified and

used as part of the sketch’s profile.

33)  Can we select non-planer surf ace as sketch plane?

No, we cannot select a non-planar surface as sketch.

34)  What are the different options available in quick trim command?

BREAK & RUBBER in removes part of the element, which is clicked.

BREAK & RUBBER out removes part of the element, which is not clicked.

BREAK & KEEP keeps both parts of elements after breaking.

35)  What do CATIA P1, CATIA P2 AND CATIA P3 mean?

P1, P2 and P3 will indicate the different types of platforms of CATIA.  Higher the number

sophisticated will be the software.

36)  What is kernel?

The kernel is the basic indispensable part of an operating system that allocates resources

such as low-level hardware interfaces & security.

37)  What is the kernel of CATIA?


38)        Is it possible to directly enter the part design workbench, when we start the CATIA session, instead of assembly design workbench?

No, we cannot enter directly into the part design.

39)  What is the importance of sketch tools?

This tool bar only appears when you are in sketcher workbench.  The four tools found in

this tool bar are toggle tools.  When tool is highlighted the tool is on.  This particular tool

bar changes depending on what other sketcher workbench tool is currently selected.

40)        How many degrees of freedom are there for points, lines, circles & ellipse in 2 dimensions?

Degree of freedom for points & ellipse is 2 for circles it is 3 & for ellipse it is 5 in two


41)  What is the meaning of mean dimension?

Mean dimension is the dimension that should be mean of all the dimensions, which are


42)  How many types of environment are available to start CATIA?

(1)               From desktop (motif)

(2)               From console (dterm)

43)  What is hlr & nhr? What is their purpose?

Hlr = hidden line removal

Nhr = no hidden line removal

Their purpose to visualize the solids in diffent modes.

44) What are Master W/S and Detail W/S?

Each model can have one Maser Workspace, in which the model is created & manipulated.  A model can have zero or more workspaces called detail workspaces.  These are auxiliary workspaces, contain elements that are to be duplicated to several locations in he Master.  workspace.  In addition, Detail workspace can also be organized into separate Library files using the LIBRARY FUNCTION. These can be shared with models to Allow Organizational standardization
