Q.8 What is use of construction elements?

Ans: Construction elements assist in sketching the required profile in sketcher workbench.

Q.9 What is SKETCH TOOLS in sketcher work bench and explain the importance of it?

Ans: SKETCH TOOLS in sketcher workbench are the commands, which find their very uses in creating sketches. Sketch tools are namely geometric and dimensional constraints, construction elements and grid options. 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.

Q.10 Difference between geometrical and dimensional constraints?

Ans: Geometric constraint is a relationship that forces a limitation between one or more geometric elements.

Dimensional constraint is a constraint, whose value determines the geometric object measurement.

Q.11 What is show hide mode?

Ans: 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.

Q.12 Is it possible to hide specification tree?

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

Q.13 How do you measure arc length?

Ans: We can measure an arc length by help of 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.

Q.14 What is the meaning of true dimensions?

Ans: True dimension is the dimension desired after the machining. In other words, this is the value that should be attained after the machining.

Ans: Ellipse, Hyperbola and Parabola.

Q.19 What is the difference between symmetry command and mirror command?

Ans: In symmetry command, the original sketch is deleted and the new one is created about the reference plane but with the help of mirror command we can retain both the new one and the original sketch about the reference plane.

Ans: Nurbs are the types of curves.

Q.21 How many types of co-ordinates systems are there?

Ans: Three, namely, Cartesian. Polar and spherical co-ordinate systems.

Q.22 Difference between trim and quick trim?

Ans: In trim option, we can extend a line along with trimming of other of other unwanted elements. In quick trim we can only trim a line or curve and we can not extend or shorten it.

Q.23 What is use of sketch analysis?

Ans: To check the whether the sketch is fully closed or not so that the sketch can be used for further operations in part design.

Q.24 Where do we use axis?

Ans: Axis is uses in creating revolve feature, eg., shaft.

Ans: Axis is visible in part design mode and can be selected but construction elements are invisible in part design mode and are not selectable.

Q.26 Can we redefine the sketches?

Ans: Yes

Q.27 Can axis can be convert in line or vice versa?

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

Q.28 How many axes can be create in a single sketch?

Ans: Only one axis can be created in single sketch, if more than one axes are drawn then only one of them, the least one will be axis and others will be converted into reference elements.

Q.29 What is the function of mirror command in sketch?

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

Q.30 If I do not want relation between original and mirrored element what should I do?

Ans: Explode and the relation between the original and mirror elements doesn’t exist.

Q.31 What is use of isolate in sketcher workbench?

Ans: Isolate is used when 3d geometry is projected onto a sketch in order to be modified and used as part of the sketch’s profile.

Q.32 Can we select non-planer surface as sketch plane?

Ans: NO, we cannot select non planer surface as sketch.

Q.33 How may degrees of freedom are there for points, lines, circles and ellipse in two dimensions?

Ans: Degree of freedom for point and line is 2, for circle it is 3 and for ellipse it is 5 in two dimensions.

Q.34 What is difference between isolate and separate?

Ans: Isolate- deletes logical link between the elements.

Separate- Separates lines, curves, faces from there links with other elements.

Q.35 What is the kernel of CATIA?

Ans: C NEXT.




Ans: Computer added (Design/ Manufacturing/ Engineering)/ Product Life cycle Management/ Virtual Product Module/ Virtual product data management/ Computational fluid Dynamics.

Q.37 Is it possible to create pocket or groove as first feature in CATIA?

Ans: Yes, it is possible in CATIA.

Q.44 Is it possible to create negative body?

Ans: Yes, using insert menu and insert body option.

Ans: Scaling- Resizing the body to the scale that you specify, in all the direction equally.

Affinity – Resizing the body to the scale, which you specify in a particular direction only, specified by you.

Q.58 What is the use of law function?

Ans: The uses of law function involve the creation of geometry to control the differing aspects of a surface.

Q.59 What are solid primitives?

Ans: Solid primitives are the ready-made features available in a particular for use. One just need to enter the dimensions and can have solid ready-made e.g – Box, cylinder, Cone, Sphere.

Q.60 What is ‘reference surface’ option in ribs and slots?

Ans: It sweeps the profile while keeping the angle value between the axis and the reference surface constant.


Q.61 What is thickness of surface?

Ans: Infinitely less

Ans: Yes, we can set default colour for surface in CATIA.

Ans: Extrusion, revolve, sweep, fill and multi-section.

Q.65 What is use of ‘federation’ option in ‘join’?

Ans: The purpose of federation is to regroup several elements making up joined surface or curve. This is especially useful when modifying linked geometry to avoid respecifying all input elements.

Q.66 Is it possible to perform a shell operation on a sphere?

Ans: Yes, we can shell a sphere. For this we need to just select the shell command and give wall thickness. If we select the sphere as object to be shelled then it will show some error and we cannot shell it.

Q.67 What is healing of geometry?

Ans: This task shows how to heal surfaces, that is, how to fill any gap that may be appealing between two surfaces.

Q.68 What is smoothening of curves?

Ans: This task shows how to smooth a curve, i.e., fill the gaps and smooth the tangency curvatures discontinuities, in order to generate better quality geometry when using this curve to create other elements, such as swept surfaces for examples.

Q.69 What is ‘simplify results’ in join?

Ans: Checking this button allows the system to automatically reduce the no of elements in resulting join whenever possible.
