NX is a 3D CAD/CAM software initially released in 1973. It simplifies complex product designs through modeling, assembly, drafting and other environments. In the modeling environment, users can create solid models using 2D sketching, extrude, revolve, sweep, boolean operations, and advanced tools like holes, patterns, and mirrors. Assemblies bring together component parts using alignment, concentric, distance and other geometric constraints. NX is commonly used in aerospace and automotive industries for mechanical designs.

1. Introduction to NX
 Initial release in 1973.
 It simplifies complex product designs.
 It is very simple, useful and powerful
software.
 It is also used in aerospace,
automotive companies.

2. Part Navigator
 The Part Navigator provides a visual representation
of the features in the work.
 It shows all the entities used during
modeling.
 It allows you to perform various
editing actions on those features.

4. Modelling environment
The Modelling environment is a feature-based
environment in which you can create solid models.
 Two dimensional sketching
 Advanced Modelling tool

5. Two dimensional sketching
You can directly create a sketch on a Plane in Modelling
application. In most cases, Modelling starts from a 2D sketch
and then Extrude, Revolve or Sweep the sketch to create
solids. Many complex shapes
that are otherwise very difficult
to model can easily be drawn by
sketching.

8. Boolean Operations
These options can be used when two or more solid
bodies share the same model space in the part file.
 Unite
 subtract
 Intersect
Unite
The unit command adds the Tool body with the Target
body.

9. Boolean Operations
 Subtract:
When using the subtract option the tool body is
subtracted from the target body.
 Intersect:
This command leaves the volume that common to
both target body and tool body .

11. Advance modelling tool
 The advanced modelling tools are mostly used to
place different types of standard and User-
defined features on a model. Most of the
mechanical designs are created using the
advanced modelling.
 Hole
 Mirror feature
 Pattern feature

12. Pattern feature
 The Pattern Feature tool is a very versatile tool in
NX. This tool is used to create the linear and
circular patterns of features. It is also used to
create the polygon, spiral, along curve, helix
patterns.

15. Assembly Environment
The Assembly environment is used to create the
interrelationship between the component parts.
 Touch/Align
 Concentric
 Distance
 Parallel
 Perpendicular
 Angle
