catia v5 interview questions and answers pdf

9. What is the function of mirror command in the sketch and what should what should we do to remove the relation between original and mirrored elements?

15. What is the difference between a stacked dimension and chained dimension mode while using the auto constraint option?

16. What are the different conic sections? How many dimensions are required to constrain the ellipse and what is the rho value for ellipse, parabola, and hyperbola?

20.What is sketch analysis in CATIA? Can we delete useless elements from the sketch, in the sketch analysis command? If yes, please describe it.

24. What do you understand by mean dimension? How many degrees of freedom are there for points, lines, circles, and ellipse in two dimensions?

The sketch is a 2D profile that is utilized to make 3D models. To start making 3D models one normally begin with a 2D sketch. Sketches are made in the Sketcher Workbench utilizing wireframe components (i.e., lines, curves, circles, and so forth). The Sketcher Workbench is utilized to make 2D geometries planned for use in the Part Design Workbench and different workbenches. Generally a 2D geometry is viewed as the beginning stage for most CAD models – a basic 2D sketch can be ‘expelled’ into a 3D shape, promote 2D sketches can be utilized to make pockets in the surface of this shape and draws can be utilized to characterize ‘cushions’ (expulsions) on the surface of 3D objects.

NURBS (non-uniform rational B-splines) are mathematical portrayals of 2-or 3-dimensional objects, which can be standard shapes, (for example, a cone) or freestyle shapes, (like cars). NURBS are utilized as a part of PC graphics and the CAD/CAM industry and have come to be viewed as a standard method to make and represent to complex articles.

This is an extraordinary tool when you are working on an asymmetrical sketch. The mirror highlight can be utilized inside sketches, parts (adding sheet metal, elements, and surface bodies), and assemblies. Mirror command in design makes a copy of the sketch about a reference plane. If we need to evacuate the connection amongst unique and mirror elements, we have to detonate, and the connection between the original and mirror components will be evacuated.

Show mode empowers us to see the accessible components opened whereas, in Hide mode, we can hide the required components from the view on a provisional premise which boosts screen space. With the assistance of F3 button on the keyboard, it is conceivable to hide specification tree, but it must be ensured that options in Tool command must be enabled to allow this.

Interview either for your first job or for the job you are trying to switch will always make you feel tense. If you have an interview on CATIA and you are looking out for interview questions and answers related to this then you must go through these the list given below, as it can help you a lot. CATIA has a vast scope in every field but to get selected in any MNC you must clear the interview.

Best CATIA Interview Questions and Answers

Ans:CATIA is the abbreviated form of Three Dimensions Interactive Applications, which is useful in various stages of product development, including conceptualization, design, engineering, and manufacturing.

CATIA assists in collaborative engineering across disciplines around its 3D-Experience platform, including surfacing & shape design, electrical, fluid, and electronic systems design, mechanical engineering, and systems engineering.

CATIA helps in designing electronic, electrical, and distributed systems such as fluid and HVAC systems, all the way to the production and certification for manufacturing.

The Best CATIA Interview Questions & Answers

A) The direction that is parallel to the vertical axis is referred to as vertical direction. The VDirection is mostly used to constrain a sketch.

22) What is the need of surface modeling?

A) The product and industrial designers these days are giving importance to product styling and providing a unique shape to components. Generally, this is done to make sure that the product looks attractive and presentable to the customer. The shape of products are managed using the surface modeling techniques. Surface models are three-dimensional models with no thickness and unlike solid models, they do not have mass properties.

23) How does CATIA V5 helps in surface modeling?

A) CATIA V5 provides a number of surface modeling tools to create complex three-dimensional surface models. Various workbenches in CATIA V5 with surface creation tools are:

  • Wireframe and Surface Design.
  • Generative Shape Design.
  • FreeStyle.
  • 24) What is ASSEMBLY MODELING?

    A) Assembly modeling is the process of creating designs that consist of two or more components assembled together at their respective work positions. The components are brought together and assembled in Assembly Design workbench by applying suitable parametric assembly constraints to them.

    25) How many types of Assembly Design Approaches are there in CATIA?

    A) In CATIA you can create assembly models by adopting two types of approaches. The first design approach is the bottom-up approach, and the second one is the top-down approach.

    26) Can you explain Bottom-up Assembly approach?

    A) The bottom-up assembly is the most preferred approach for creating assembly models. In this of approach, the components are created in the Part Design workbench as (.CATPart) file. Then the product (.CATProduct) file is started and all the previously created components are inserted and placed in it using the tools provided in the Assembly Design workbench. After inserting each component, constraints are applied to position them properly in the 3D space with respect to other components.

    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.

    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.

    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.

    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.

    42) How many types of environment are available to start CATIA? (1) From desktop (motif) (2) From console (dterm)
