Smart Router: Quick Path

Quick Path automatically creates a collision free path between two specified
locations, and optionally, through specified intermediate locations. The
resulting path comprises lines and arcs, but not splines, and avoids obstacles
by a specified clearance value. You can adjust the path for the final desired
path.
USE:

Use Quick Path to avoid manually creating a collision-free non-trivial path
between two locations.

Block, Cylinder, Sphere, and Cone associativity

The Block, Cylinder, Sphere, and Cone commands are now associative to their respective point, vector, and curve positioning objects.
If you subsequently move one of the positioning objects, the feature updates associatively.


Why should I use it?
This new associativity makes primitive features more useful for modeling prismatic objects such as machining fixtures.


Where do I find it?

Restore last NX session

You can now use bookmarks to save and restore the following characteristics
of your NX session:
• The load status of parts
• The configuration rules
• The Assembly Navigator’s expand/collapse state
The enhanced bookmarks also support sessions that have assemblies with
both transient and persistent nodes.
Bookmarks are stored in the native NX file system, regardless of whether you
are in native NX or Teamcenter Integration for NX.
Use:
This function lets you save time by preserving the state of your current NX
session, so you need not reset the above characteristics when you return to
your work in later sessions.
How to use it?

WAVE General Relinker

The General Relinker dialog box now has the following enhancements and
changes:
• You can specify whether suppressed components should be included
as source objects by selecting or clearing the Include Suppressed
Components check box in the Settings group.
• You can define the source searching scope for the relinking operation by
setting the new Source Scope option (in the Relink group) to either Parts
in Assembly or Parts in Session.
• You can control whether the General Relinker looks for non-broken WAVE
links, as well as broken ones, with the new Include Non-broken WAVE
Links check box. When this check box is not selected, update performance
is faster, and non-broken links that share the same naming convention as
broken links are not reparented.
• Relink Scope (in the Relink group) is now Target Scope.
• Face/Curve Direction Adjustment, in the Settings group, is now called
Face Normal/Curve Direction Adjustment.

Geometry selection for designing in an assembly context

You can now easily select geometry outside the work part for many NX
Modeling commands. You can automatically copy geometry you select outside
the work part into the work part as either WAVE geometry (which updates
when the source geometry changes) or non-associative geometry (which does
not update).

This functionality uses two new options on the Selection bar: (1) Select
Scope and (2) Create Interpart Link.
You can control interpart selection with the Select Scope option to select
geometry from assembly components other than the work part.
Select Scope options are:
• Entire Assembly
Use this option to select geometry from any component in the assembly.
• Within Work Part and Components
Use this option to limit the selection of geometry to the current work part
and its components, if it is a subassembly.
• Within Work Part Only
Use this option to limit the selection of geometry to the current work part.
If the Select Scope option is not available for a command, this indicates that
the command does not support this design in context functionality. In this
case, you can still use one of the other traditional methods to create interpart
links, such as Wave Geometry Linker.
When selecting geometry from a component other than the work part, you
may choose to create an interpart link or to use the geometry unassociatively.
To create an interpart link, turn on the Create Interpart Link option before
making a selection. For commands where you make multiple selections, you
can turn this option on or off independently for each selection.

Radial Engine Assembly

In this exercise you will create the Radial Engine assembly shown in below Figure.

 The Radial Engine assembly will be created in two parts, one will be the sub assembly and the other will be the main assembly. The dimensions of the components of the Radial Engine assembly are shown in below  Figures 

Synchronous modeling: Move Face

Move face is an option to move the faces of the particular component to certain limit as per the requirement.
Basically this option is useful when you have parametric models and just to show 3 models to somebody like 3rd party without editing the main features of the component.

The above image shows how to open Synchronous modeling.
Let us explore the first option in this tool
MOVE FACE:

>Select the face which you want to move.

>You have so many options to move the face like

Distance,

Angle,

Point to Point etc.

>You can choose any one option as per the convenience .

(Here I shown with distance)

You  can see an option called FACE FINDER in the above tool .

There are three options in that.

Results,Settings,Reference.

in Settings,You can set the options as per requirement.

Reference is the option to call the component to particular location.

Assembly Load Option

To define how and where NX load part file, we need to configure some basic function like, save, open and assembly.
Dialog box will appear, like the below picture, from the dialog box here we can set up load the file first time as may be required, it is easier for us in working with Unigraphic later.

 1. Part version
You can set whether each time to load a new file or open a file starting from the folder, or history. UGS default is the folder.

2. scope
You can choose all the components directly on the load time, or just based on the stored data, or other options, are generally used are all components (including part assembly).

3.Reference Sets
You can call the components as per the reference set created while modeling.

4. Save Load option
Save to file, serve to redirect the folder to load the first time, after the set, every time you open a new file, the folder will be automatically redirected to it.
So is the open from the file, after we set the folder, each time it opens the file it will automatically be redirected to a folder that was set.

Offset Face

Go to Insert-->offset/Scale-->Offset Face

Its a simple command for extending the faces of particular component without going and modifying the sketch.

A face of the block is extended upto 10mm using offset Face command

Offset Surface

Go to Insert-->offset/scale-->Offset Surface

In the offset surface command 
in feature bar you can see OUTPUT

You have two options in this,
1.One feature for connected faces 
This option is useful when you have to create the envelope for the particular component as the tolerance purpose.In this all the faces offset with the connectivity.

2.One feature for each face.
You wont see any connectivity in this command.Each face can be offset individually without any connectivity.

Shell Command

Initially create rectangle either through creating a block command or through sketch.
Then open the shell command from
insert-->offset scale-->shell as shown in below

there are two options in the shell command,
1.Remove faces,then shell
This option is useful when you want to remove the inner material and create a thickness for the out wall as shown in below image

the thickness can be variable with the face,
different faces can select for different thickness

2.Shell all the faces.
In this option out body remains same but inner material removed as shown in below image.

By applying this we cant find the shell applied or not but if you see the section for the block you will find the thickness to the walls.

after section only shell can be visible

Difference between Chamfer and Blend

1.Blend:
Blend operations add or subtract material to round (fillet) edges.
• Uni graphics provides 3 kinds of blends:
Edge Blend
• Is the only type of blend you need to know how to perform for this class.
• Can be constant or variable radius.
• Good practice rule:
Face Blends
• In face blends you choose two faces instead of an edge.
• Face Blends will trim faces if required.
Soft Blends
• Soft blends are used for styled “Class A” surfaces.
• The curvature varies smoothly


2.Chamfers
• Chamfer add or remove material to create beveled edges.
• The same rules apply to creating chamfers as to creating edge blends.
• Options include:
– Single offset
– Double offset
– Offset and Angle

Loading a File from folder

Change folder first time load for save or open file
To define how and where NX load part file, we need to configure some basic function like, save, open and assembly.
Dialog box will appear, like the below picture, from the dialog box here we can set up load the file first time as may be required, it is easier for us in working with Unigraphic later.

1. Part version
You can set whether each time to load a new file or open a file starting from the folder, or history. UGS default is the folder.


2. scope
You can choose all the components directly on the load time, or just based on the stored data, or other options, are generally used are all components (including part assembly).

3. Save Load option
Save to file, serve to redirect the folder to load the first time, after the set, every time you open a new file, the folder will be automatically redirected to it.
So is the open from the file, after we set the folder, each time it opens the file it will automatically be redirected to a folder that was set.

MATING CONDITIONS IN ASSMEBLY

When component objects are added to the assembly part file, each component object is mated with the corresponding objects. By putting mating conditions on components of an assembly, you establish positional relationships, or constraints, among those components. These relationships are termed mating constraints. A mating condition is made up of one or more mating constraints. There are eight mating constraints as shown below.

• Mate – Planar objects selected to mate will become coplanar and the direction of the normal's will be opposite to each other

 Align – Planar objects selected to align will be coplanar but the normals to the
planes will point in the same direction. Centerlines of cylindrical objects will be in line with each other.
• Angle – This fixes a constant angle between the two object entities chosen on the components to be assembled.
• Parallel – Objects selected will be parallel to each other.
• Perpendicular – Objects selected will be perpendicular to each other.
• Center – Objects will be centered between other objects, i.e. locating a cylinder along a slot and centering the cylinder in the slot.
• Distance – This establishes a +/- distance (offset) value between two objects
• Tangent – This establishes a tangent relationship between two objects, one of which has to be curved such as a free form surface, a circle, a
sphere, or a cylinder.
The Mating Conditions dialog box is shown below

TYPES OF ASSEMBLY

There are two basic ways of creating any assembly model.
• Top-Down Approach
• Bottom-Up Approach
Top-Down Approach
The assembly part file is created first and components are created in that file. Then individual parts are modeled. This type of modeling is useful in a new design.

Bottom-Up Approach
The component parts are created first in the traditional way and then added to the assembly part file. This technique is particularly useful, when part files already exist from the previous designs,and can be reused.

Mixing and Matching

You can combine these two approaches, when necessary, to add flexibility to your assembly design needs.

ASSEMBLY INTRODUCTION

This chapter introduces assembly modeling. Every day, we see many examples of components that are assembled together into one model such as bicycles, cars, and computers. All of these products were created by designing and manufacturing individual parts and then fitting them together. The designers who create them have to carefully plan each part so that they all fit together perfectly in order to perform a function.


OVERVIEW

NX 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 virtual 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. The following figure is a schematic, which shows how components are added to make an assembly.

TERMINOLOGIES

Assembly
An assembly is a collection of pointers to piece parts and/or subassemblies. An assembly is a part file, which contains component objects.
Component Object
A component object is the entity that contains and links the pointer from the assembly back to the master component part.
Component Part
A component part is a part file pointed to by a component object within an assembly. The actual geometry is stored in the component part and is referenced, not copied by the assembly

Drafting Introduction in depth

The Drafting Application is based on creating views from a solid model as illustrated below.
Drafting makes it easy to create a drawing with orthographic views, section views, imported view, auxiliary views, dimensions and other annotations.

Some of the useful features of Drafting Application are:
1) After you choose the first view, the other orthographic views can be added and aligned with the click of some buttons.
2) Each view is associated directly with the solid. Thus, when the solid is changed, the drawing will be updated directly along with the views and dimensions.
3) Drafting annotations (dimensions, labels, and symbols with leaders) are placed directly on the drawing and updated automatically when the solid is changed.
