2. INTRODUCTION TO NX
NX, formerly known as NX Unigraphics or usually just UG, is an
advanced high-end CAD/CAM/CAE software package originally
developed by Unigraphics, but since 2007 by Siemens PLM Software.
It is used, among other tasks, for:
• Design (parametric and direct solid/surface modeling)
• Engineering analysis (static; dynamic; electro-magnetic; thermal,
using the finite element method; and fluid, using the finite volume
method).
• Manufacturing finished design by using included machining
modules.
• NX is a direct competitor to Top Solid, CATIA, Creo, Autodesk
Inventor, and SolidWorks.

12. ORIENT VIEW
Home key: Orients the current view to Trimetric.
End key: Orients the current view to Isometric.
F8 key: Orients the current view to a selected planar face or datum
plane or the planar view (top, front, right, back, bottom, left) that is
closest to the current view orientation.
View triad
13. COORDINATE SYSTEMS
Absolute Coordinate System
Work Coordinate System
The Absolute Coordinate System is the coordinate
system from which all objects are referenced.
The Work Coordinate System (WCS) is what you will
use for construction when you want to determine
orientations and angles of features. The axes of the WCS
are denoted XC, YC, and ZC. (The “C” stands for
“current”)
14. SKETCHING
Sketching A Sketch is a named set of 2D curves and points located on a
specified plane or path. You can apply rules, in the form of geometric and
dimensional constraints, to establish the criteria your design needs.
Ways to use sketches
20. CONVERT TO/FROM REFERENCE OVERVIEW
Use the Convert To/From Reference command to convert sketch
curves from active to reference, or dimensions from driving to
reference.
28. TYPES OF SWEPT FEATURES
• Extrude – Sweep a section string (1) in a linear direction for a
specified distance.
• Revolve – Rotate a section string (1) around a specified axis (2).
29. • Sweep Along Guide – Sweep a section string (1) along a
guide string (2).
30. BOOLEAN OPERATIONS:
• Unite: The unite command adds the Tool body with the Target
body. For the above example, the output will be as follows if Unite
option is used.
31. • Subtract: When using the subtract option, the Tool body is subtracted from the
Target body. The following would be the output if the rectangle is used as the
Target and the cylinder as the Tool.
• Intersect: This command leaves the volume that is common to both the Target
body and the Tool body. The output is shown below.
32. PATTERN FEATURE
• The Pattern Feature tool is a very versatile tool inNX. 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.
34. Surfacing
In NX, surfaces are created in the form of single or multiple patches. With the increase
in patches, the control over the shape of the surface also increases. In NX, surfaces are
known as sheets and surface modelling

37. Assembly
Assembly is a part file that contains the individual parts. They are added to the part
file in such a way that the parts are virtually in the assembly and linked to the
original part. This eliminates the need for creating separate memory space for the
individual parts in the computer. All the parts are selectable and can be used in the
design process for information and mating to insure a perfect fit as intended by the
designers.
• Touch/Align
• Concentric
• Perpendicular
• Parallel
• Bond
• Angle
• Center
• Distance
38. 3D CAD MODELLING
• NX mechanical design software delivers comprehensive modeling,
enabling you to use the most productive modeling approaches
interchangeably – from explicit solid and surface modeling to
parametric and direct modeling.

40. DRAFTING
The Drafting Application is designed to allow you produce and maintain industry
standard engineering drawings directly from the 3D model or assembly part.
Drawings created in the Drafting application are fully associative to the model
and any changes made to the model are automatically reflected in the drawing.
The Drafting application also offers a set of 2D drawing tools for 2D centric
design and layout requirements
41. Types of views Used in Drafting
Base View - The first view created in a drawing. The
base view is the source for subsequent views and
controls the scale and alignment for them. You can create
one or more base views on a drawing sheet.
Projected View -An orthographic or isometric view that
is generated from a base view or other existing view.
You can create multiple projected views in a single
operation. The position of the cursor relative to the
parent view determines the orientation of the projected
view.
42. Section View - A view created by sketching a line that
defines a plane used to cut through a part or assembly.
You draw the cutting line when you create the view, or
select it from a sketch associated to the parent view
Detail View - An enlarged view of a specified portion
of another drawing view. By default, the scale of the
detail view is double the scale of the parent view, but you
can specify any scale
BOM - Bill of materials or product structure (sometimes bill
of material, BOM or associated list) is a list of the
raw materials, sub-assemblies, intermediate assemblies, sub-
components, parts, and the quantities of each needed to
manufacture an end product
45. Initialize Project
You can use the Initialize Project command to:
a) Create a new MOLD design project.
b) Add additional products to an existing project
to create a family MOLD.
When you create a new project, you can specify:
a) The MOLD units (Inch or Millimetres)
b) The path (folder location) to the project part
files
c) The project name (file name prefix for all
project part files)
d) The material type and shrinkage factor
Part Attributes used for drawings and the Bill of
Materials? A template assembly.
46. Mold CSYS
Shrinkage
MOLD CSYS is used for the correct
orientation and Position Relative to the
MOLD assembly.
Shrinkage is a scale factor applied to a product
model to compensate for part shrinkage while
cooling. Go to Shrinkage:
48. Check Regions:
Analyze the model faces for draft angles, color faces according
to their draft condition find faces that cross over the parting
find undercut faces and edges and split faces.
1.) Go to Check regions
2.) Give direction
3.) Keep existing and calculate
4.) Go to Face check Positive Negative and Vertical draft
face.
5.) Also check crossover face, undercut area and undercuts
edge.
6.) Then go to regions
7.) Set the regions color
8.) Then check the core and cavity region
9.) Click on ok.
49. Patch Surface:
Patch the surface if required its prevent the through
hole of the body
Define Regions:
DEFINE REGIONS is use for define the core and
cavity surface also you can analyse the number of
core and cavity surface.
50. Design Parting Surface:
