Catia V5 Interview Question and Answers

After long time I am writing a blog again, here I am going to write ANSWERS to all my question. Which I have asked in my earlier Blog CATIA V5 Interview Questions. Please refer the link

Q. What is the file extension of a part file?
Ans: File Extension of Part file is dot CATPart (.CATPart)

Q. Which are the Neutral file extensions we can use for the part file?
Ans: IGES/igs, STEP/stp, STL, WRL, etc

Q. Can you create a Block using a line/ Is it possible to extrude a Line or Open profile using PAD.
Ans:Yes, you can create a block using line. when you are extruding a line or any open profile you can check thick option in Pad feature (to avoid Error message). You can Give limit one , Limit Two and Thickness one and two. You will get Block from line and thin sheet from any open profile.
Note: Don’t use this option to create a sheet metal part using part design.

Q. What is Merge ends in Pad.
Ans: Please refer the following figure-1 for merge ends in pad. Create a hollow block. On inside surface create an open profile. To extrude an open profile select thick option and it will extrude by taking the length of curve. When you check merge ends option solid will extend up to the next wall here it will maintain the tangent continuity.

Q. Application of Multi-pad.
Ans: Application of multi pad is to extrude profiles to different height we can use it . Please ref the following figure-2.

Q. How do you create a corner chamfer for a bolt/Nut.
Ans: Using Grove option you can create a corner Chamfer for Bolt.

Q. What the difference between Merge Rib ends and Merge ends in Rib option.
Ans: Merge rib ends will extend a solid along center curve up to the solid and merge ends will extend a solid along profile end points to solid.

Q. What are the uses of coupling Curves and Guide curves in Loft/ Multi-section Solid.
Ans: Coupling curves are used to get number of edges on the solid and Guide curves are used to get the shape to a solid.

Q. what are the limiting elements in Multi-section Solid.
Ans: If you are selected N number of profiles in Loft or Multi-section and creating a solid along a spine or through the guide curves . the Limitations are first and last profile .

Q. What is Trim Ribbons in fillet?
Ans: If the fillet materials are over lapping each other to remove that overlapped material trim ribbons are used OR It will remove the overlapped material in fillet.

Q. what is Circle fillet?
Ans: Due to concave and convexity the fillet on the edges ll try to close or it will expand to avoid and maintain the parallel on the creating fillet Circle fillet is useful.

Q. can you create a hyperbolic fillet in Catia? if yes How?
Ans: Yes we can create a hyperbolic fillet. by defining the parameter value above 0.5 and less than 1.0 you will get hyperbolic fillet. If the parameter is 0.5 resulting is parabolic fillet. If parameter is less than 0.5 and greater than 0.0 you will get Elliptical fillet.

Q. can you create a sheet metal parts in Part design. How
Ans: You can create sheet metal parts in part design by using SHELL option. Here the shell will be your last feature to complete the model.

Q. Can you operate a shell command on Spear.

Q. Is it possible to give a variable distance for a features in rectangular pattern.
Ans:Yes we can give a variable distance in Rectangular pattern. Select the option Instances and Unequal spacing.

Q. What is use of keep specification in Patterns.
Ans:Keep specification in the pattern is, it will maintain the same specifications what you have used for the patterned feature to the entire Duplicate.

Q. what are the differences between Mirror and symmetry.
Ans: Differences between mirror and Symmetry
Reference will be a plane or any planar surface
Reference may be a Plane, Point or a line
It will create a Duplicate
Orininal element will be translated to other side of the reference
Can be used for a single or multiple Features
It will consider a current solid in a body

Q. Can you use symmetry reference as a point or line
Ans: Yes

Q. can you make a symmetry of single feature out of 10 features.
Ans: No

Q. what is the difference between ADD and ASSEMBLE in boolean operation. (I can confuse any one for this question)
Ans: Please refer blog ADD and ASSEMBLE in boolean operation

Q. What Is remove Lump?
Ans: Remove lump is a only option we can use within a inserted body or in a part body to remove the unwanted lump.

Q. Is there any alternate option for remove lump?
Ans:Alternative option for remove lump is remove faces in Dress-up feature.

Q. Is it possible to use pad as alternative for stiffener?
Ans: Yes

Q. What is power copy?
Ans: Power copy is a feature using this u can copy a single or multiple features and save it whenever required you can insert (Similar to Block command in AUTOCAD)

Q. What is UFC?
Ans: UFC = User Feature Creation. Its again similar to Power copy

Q. What is the difference between PC & UFC.
Ans:The Difference between Power copy and UFC is . when you insert a power copy you will get a Feature or sketch what you have copied when you are creating an Independent feature. But when you insert UFC you will get a user feature and you get get an independent feature.

Q. what is the use of Design table? when you use it.
Ans:Design Table is linking parameters of a model to EXCEL. Its used for a standard parts like Bush, Steel structures (i.e. I , C and L channels) Nut, bolt , washers, O-Rings and Keys etc.

Q. what is the difference between SEW surface and SPLIT.
Ans: SEW and Split is almost same to split the solid we can use . when you are using a sew surface if there is a air between the solid and surface it fill with Solid material.

Q. Can you create Fillet with 12mm radius for a 10 X 10 X10 cube
Ans: YES use Edges to keep to create 12mm Radius fillet for 10 mm Block.

Q. What is blend corner? when you use it.
Ans: If the selected three Edges are meeting at the same point then that point is Blend corner . Its used in plastic parts to avoid sharp edges on a solid. By giving a setback distance from the corner you can stop the fillet and get the blend at the corners. Please refer the following figure-3.

Q. what is use of Spline in multi-section solid.
Ans: Spline in multi-section solid is used to follow solid along the Curve.

Q. what is the alternate option for Intersect Boolean option.
Ans: Solid Combine is alternative option for Intersection Boolean operation.

Q. How do you create a negative Polarity body in Part design?
Ans: After inserting a new body If you use Negative feature as fist feature in a body the polarity of the body will be negative. Negative features like Pocket, Groove, Slot Hole etc.

I hope you got all the answers for the questions. If anyone have any doubt please ask here I ll try to answer your Questions...
