unigraphics nx interview questions and answers pdf

The idea of virtual assembly taken to its logical conclusion leads to Master Model paradigm. We find the Bounded plane command in Insert –> Surface –> Bounded Plane.ģ4) What is meant by Master Model Concept? We find these options in section command of free form feature.ģ3) Where do you find bounded plane command? There are 22 types of Geometrical constrains in Unigraphics NX.ģ1) How many layers are there in Unigraphic (UG)?ģ2) In which command do you find strings, apex string, and spline string? Sketch curve are parametric and can constrain but basic curves are non parametric and cannot constrain them.ģ0) How many types of geometrical constrains are there in Unigraphics NX? In Rotational WCS we can give the angle by which the WCS need to rotate by typing it in the space provided, while in Dynamic WCS we can dynamically rotate the WCS and give the angle.Ģ9) What is the difference between Sketch Curves & Basic Curves? It uses X,Y and Z co-ordinates while creating model.įollowing are the three types of Co-ordinate SystemsĢ8) What is the difference between Rotational WCS & Dynamic WCS? STEP – Standard For The Exchange of Product Model DataĢ7) What is Co-ordinate System? How many types of Co-ordinate Systems are there in Unigraphics?Ĭo-ordinate System is a reference element.

IGES – Initial Graphic Exchanges Specifications.This plane is know as sketching plane.Ģ6) What is the expansion of IGES, STEP, DXF? To create a sketch, you must associate the Sketch feature to a planar object. (Restricting the degree of freedom)Ģ4) How many types of constraints are there?ġ) Geometrical constraints 2) Dimension constraints Constraints can be applied to faces or edges. Datum Axis can be either relative or fixed.Ĭonstraints limit structural movement and represent mounts and supports. Unigraphics (UG) NX Interview Questions and Answersĭatum Plane is reference feature that can be used to as construction tool in building the model.ĭatum Axis, which is a reference object you can use to create other objects, such as Datum planes, revolved features, and extruded bodies.
