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.

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 

Model a Hexagonal Nut

􀂾 Create a new file and save it as Impeller_hexa-nut
􀂾 Click the polygon icon from the toolbar

􀂾 Create a hexagon with each side measuring 0.28685 inches and constructed at the origin
􀂾 Extrude the hexagon by 0.125 inches
The figure of the model is shown below.

􀂾 Choose INSERT → DESIGN FEATURE → SPHERE
􀂾 Choose CENTER, DIAMETER

􀂾 Enter the diameter value 0.57 inches
􀂾 Enter the Point Constructor values as follows

Axes            XC      YC           ZC
Dimension   0.0      0.0       0.125

􀂾 In the Boolean operations dialog box select INTERSECT
The model will look like the following.

We will now use a Mirror command.
􀂾 Choose EDIT → TRANSFORM
􀂾 Select the model and click OK
􀂾 Click MIRROR THROUGH A PLANE
􀂾 Click on the flat side of the model as shown. Be careful not to select any edges
Click on OK

􀂾 Click on COPY
􀂾 Click CANCEL

You will get the following model.
􀂾 Choose INSERT → COMBINE BODIES → UNITE

􀂾 Select the two halves and Unite them
􀂾 Insert a cylinder with the vector pointing in the Z-direction
and with the following dimensions.
Diameter = 0.25 inches
Height = 1 inch
􀂾 Center the cylinder on the origin and subtract this cylinder
from the hexagon nut

Now, we will chamfer the inside edges of the nut.
􀂾 Choose INSERT → DETAIL FEATURE → CHAMFER

􀂾 Select the two inner edges as shown and click OK

􀂾 Enter the Chamfer Offset Diameter as 0.0436 inches and click OK
You will see the chamfer on the nut. Save the model.

Threading of a hexagonal bolt

Open the model with Hexagonal nut from my previous post:


http://unigraphicsbasicsnmaterial.blogspot.com/2011/12/model-hexagonal-screw.html

• Choose INSERT → DESIGN FEATURE →THREAD

Here you will see the threading dialog box as shown below.


There are two main options in Threading: 
1)Symbolic and 2) Detailed.

• Click on the DETAILED radio button
• Keep the thread as RIGHT HANDED
• Click on the bolt shaft, the long cylinder below

the hexagon head Once the shaft is selected, all the values will be displayed in the Thread dialog box. Keep all these default values.

• Click OK

The hexagon bolt should now look like the following. Save the model.

Model a Hexagonal Screw

Create a new file and save it as Impeller_hexa-bolt

• Choose INSERT → DESIGN FEATURE → CYLINDER
• The cylinder should be pointing in the Z-direction with the center set at the origin and with the following dimensions:

Diameter = 0.25 inches
Height = 1.5 inches

Now create a small step cylinder on top of the existing cylinder.

• The dimensions of this cylinder are,

Diameter = 0.387 inches

Height = 0.0156 inches 

• On the Point Constructor window,click the Center icon at the top
• Click on the top face of the existing

cylinder as shown in the following figure



Under the Boolean drop-down menu,
choose UNITE

The two cylinders should look like the figure shown below.

Save the model.
Next, we will create a hexagon for the head of the bolt.

• Choose the icon from the Curves Toolbar as shown

• On the Polygon window, type 6 for the number of sides

• Click OK

There are three ways to draw the polygon.
• Inscribed Radius
• Side of Polygon
• Circumscribed Radius

• Choose SIDE OF POLYGON

On the next window, enter the following dimensions.
Side = 0.246 inches
Orientation Angle = 0.00 degree

• Click OK
• On the Point Constructor window, again choose the Center icon
• Click on the top face of the last cylinder drawn 

The polygon will be seen as shown below. 

If the model is not in wireframe, click on the Wireframe icon in the View Toolbar


Now we will extrude this polygon.

• Choose INSERT → DESIGN FEATURE → EXTRUDE
• Click on all six lines of the hexagon to choose the surface that is required to be extruded
• Enter the End Distance as 0.1876 inches

The model looks like the following after extrusion

On top of the cylinder that has a diameter of 0.387 inches, insert another cylinder with the following dimensions.


Diameter = 0.387 inches
Height = 0.1875 inches


You will only be able to see this cylinder when the model is in wireframe since the cylinder is inside the hexagon head. The model will look like the following.

We will now use the feature operation Intersect.

• Choose INSERT → DESIGN FEATURE → SPHERE
• Choose DIAMETER, CENTER

• Enter the value of the diameter as 0.55 inches and click OK
• On the Point Constructor window, choose the Center icon
• Select the bottom of the last cylinder drawn, which is inside the hexagon head and has a diameter of 0.387 inches and a height of 0.1875 inches as shown below

Click OK



This will give take you the next Dialog box which will ask you to choose the Boolean operation to be performed.

• Choose INTERSECT

It will ask you to select the target solid

• Choose the hexagonal head as shown 

• Click CANCEL

This will give you the hexagonal bolt as shown below.

Check here how to add threading to the above bolt in the next post:

HIDING & SHOWING ENTITIES

Whenever you create a sketch-based feature, the sketch used to create it is retained on the screen, even after the feature is created. NX allows you to hide the sketches or any other entity on the screen using the Hide tool. To invoke this tool, press the CTRL+B keys; the Class Selection dialog box will be displayed. Alternatively, you can invoke the Hide tool from the Utility toolbar. Select the sketch or any other entity from the screen using this dialog box and choose the OK button; the selected entities will be hidden


SHOWING HIDDEN ENTITIES

To restore the display of the hidden entities, press the SHIFT+CTRL+K keys; the Class Selection dialog box and the hidden entities will be displayed. Also, you will be prompted to select the objects to be displayed. Select the entities to be displayed and then choose the OK button.


HIDING ALL ENTITIES USING A SINGLE TOOL

NX allows you to hide all entities (all datum planes, coordinate systems, sketches,faceted bodies, solid bodies, and so on) from the drawing window, using a single tool.To do so, choose the Show and Hide button from the Utility toolbar; the Show and Hide dialog box will be displayed, as shown in Figure 

click on image to enlarge

All entities are divided into three categories, Bodies, Sketches, and Datums. Select the minus sign (-) from the respective rows; the corresponding entities will be hidden. For example, if you need to hide all the sketches in the drawing window, select the minus sign (-) from the Sketches row; all the sketches will be hidden. Similarly, to show hidden entities, select the plus sign (+) from the respective row; all entities under that category will be re-displayed in the drawing window.


Toolbar: Utility > Show
Toolbar: Utility > Show and Hide



TIP:The Show and Hide tool is very useful while working with complicated models and assemblies, where datums planes, coordinate systems, and sketches are in large numbers.You can also invoke this tool by pressing the CTRL+W keys.
