CATIA | Basic Interview Questions And Answers.

CATIA  Interview Questions and Answers of CATIA.

CATIA is an acronym for Computer Aided Three-Dimensional Interactive Application. It is the most proficient, powerful and highly popular CAD i.e. computer aided design software. It is created, developed and owned by Dassault Systems of France. 

Application of CATIA

CATIA is among the very few software which has its application in about every industrial sector. It is mostly used by the designer team. The designer team of any organization needs to create a digital copy of any object which has to be manufactured. This digital copy can be created with much ease by using CATIA. It is mostly found in companies who are associated with design and manufacturing of products.

1. What is Full form of CATIA?

A. Computer Aided Three Dimensional Interactive Application.

2. What Is The Kernel Of CATIA?


3. What is the save extension of sketcher file?

A. .CAT Part

4. Does CATIA V5 work on UNIX Platform?

A. Yes

5. Is it possible to increase the size of plane boundary representation & how?

A. Yes, Go for Tools-Options- Infrastructure-Part structure-Display.

6. What Are the Default Units of LMT (length, Mass and Time)?

A. mm, Kg, Second. 

7. Is it possible to hide specification tree?

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

8. What is SHOW/HIDE option?

A. Show mode enables us to see all the components presently opened and in Hide mode we can hide the desired elements from the view for time being

9. How do you measure Arc length?

A. 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 MEASURE ITEM command.

10. How many types of environment are available to start CATIA?

A. 1. From desktop (motif)
    2. From console (dterm)

11. What is the meaning of mean dimension?

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

12. What is kernel?

A. The kernel is the basic indispensable part of an operating system that allocates resources such as low-level hardware interfaces & security.

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

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

14. What is the meaning of true dimension?

A. 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?

A. 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?

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

17. What for the animated constraint command is used?

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

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

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

19. What are different conic sections?

A. Ellipse, Hyperbola and Parabola

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

A. 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?

A. Nurbs are the type of curves

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

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

23. What are project 3D silhouette edges?

A. 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?

A. 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?

A. Axis is used in creating shaft (revolved) feature

26. Can we redefine the sketches?

A. Yes.

27. Can axis be converted into line or vice-versa?

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

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

A. 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?

A. 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?

A. 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?

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

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

A. 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?

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

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

A. 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?

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

36. Is It Possible to directly enter in to Sketcher Workbench?

A. 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…

37. Which is the tool used to exit from sketcher workbench to part design Workbench?

A. Exit Sketcher

38. What is the use of construction elements?

A. Construction elements assist in sketching the required profile in sketcher.
