Ans: CATIA (Computer-Aided Three-Dimensional Interactive Application ) is a multi-platform software suite for computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), PLM and 3D, developed by the French company Dassault Systèmes.
Ans: AutoCAD is a commercial computer aided design and drafting software application. It was developed by Autodesk. It can be used for both 2D and 3D designing. Autocad is said to have best drafting features. Whereas CATIA ,an acronym of computer aided three-dimensional interactive application.
Ans: CATPart
Q4. Which is the tool used to exit from sketcher workbench to part design workbench?
Ans: Exit sketcher.
Ans: You can can orient a sketch plane according to your requirement then you can sketch its positioned sketch.
Ans: Sketch analysis is used to check the profile is open or close, and to convert some profiles in to Reference elements and to delete. and also used to check the sketch is constrained or not.
Ans: Show mode enable us to see all the components presently opened and in Hidemode we canhide the desired elements from the view for time being.
Ans: mm, Kg, Second.
Ans: Three dimensions are required namely major axis, minor axis and the distance from the origin.
Ans: Ellipse, Hyperbola and Parabola.
Ans: 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.
Ans: Mirror command in sketch will create a copy of the sketch about a reference plane.
Ans: Explore and the relation b/w the original and mirror element doesn’t exit.
Q14. What is the use of isolate in sketcher workbench?
Ans: 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.
Ans: Nurbs are the type of curves.
Ans: Three namely Cartesian, Polar and Spherical co-ordinate system.
Ans: Degree of freedom for points & ellipse is 2 for circles it is 3 & for ellipse it is 5 in two dimensions.
Ans: Mean dimension is the dimension that should be mean of all the dimensions, which are tolerance.
Ans: Project 3D silhouette edges in sketcher will shows how to create silhouette edges to be used in as geometry or reference elements.
Ans: 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.
Ans: 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 sketching.
Ans: 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.
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: 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.
