NX 5 Assembly Constraints Demo
Overview:
This demo set will show the highlights of the NX 5 Assembly Constraints
functionality.
Demo Setup:
- Environment Variables
- Customer Defaults
- Assemblies, Site Standards, Model Reference Set, Name = MODEL
- Assemblies, Site Standards, Lightweight Reference Set, Name =
FACET
- Preferences
- Load Options
- Load Components: No Components
- Use Partial Loading: On
- Preferred Reference Sets: As Saved
- Apply to All Levels: On
- Open part 141-f10002
- Reorder Assembly Navigator columns so that
Component Name is on the far left (top)
- Select the Component Name column heading so
that it is sorted
- RMB in the column heading and toggle on
"Show Component Groups"
- RMB over the "Components to Constrain"
group and select Components, Open, Component
- In Phase 21, Pick the Assembly Constraints
icon so that you can select Yes on the following dialog prior to
starting the demo. After the Assembly Constraint dialog appears,
you can close it. This message will only appear once per session.
Note: The Assembly Constraint dialog
stays open during this entire demo.
Note: If you are giving this demo without a spaceball, make sure that
the graphics window has focus before using the roller ball on the
middle mouse button between each selection. By default, the focus
changes back to the Assembly Constraints dialog after each graphically
selection. If the roller ball is used (to zoom in/out) when the
dialog has focus, the constrait type will change and all of your
selections up to that point will be lost.
Demo Section 1: Create "Touch Align"
Constraint using Center Lines
- Click on the Assembly Constraints icon.
(In previous releases, this icon was known as Mating Conditions.)
- The Assembly Constraints dialog will appear on the dialog rail.
- With the Assembly Constraints dialog open, mouse over the
cylindrical surface on the yellow knuckle (141-F10002_5_5_1).
(Notice that while the cylindrical surface is highlighted, the
centerline appears. You can now move your mouse over the
centerline to get it to highlight.)
- MOUSEOVER ->
- Select the centerline as displayed in the mouseover image above.
- Select the centerline on the gray axle (AXLE FRONT) the same way
(as shown in
the mouseover below).
- MOUSEOVER ->
The constraint will be created and displayed as blue in the image
below
- Press the Apply button to retain this constraint.
Demo Section 2:
Create "Center 2 to 2" Constraint
- In the Assembly Constraints dialog, use the pulldown to change
the constraint type to Center and the Subtype to "2 to 2".
- MOUSEOVER ->
- Select the top face on the yellow knuckle (141-F10002_5_5_1) as
shown in the image below.
- MOUSEOVER ->
- Rotate the part to select the bottom
face on the same part as
shown in the image below.
- MOUSEOVER ->
- Select the top face on the gray axle
(AXLE FRONT) as
shown in the image below.
- MOUSEOVER->
- Rotate the part to select the bottom
face on the same part as
shown in the image below.
- MOUSEOVER ->
Demo Section 4:
Drag Component while Maintaining Constraints
- While the Assembly Constraints dialog is still open, pick and
drag the ball joint so that you can select the faces easier.
- MOUSEOVER ->
- Press the Apply button to retain this Move
Demo Section 5:
Create "Touch Align" Constraint on Conical Surface
- Press the reset button in the top right of the Assembly
Constraints dialog to return to default options (Touch Align).
- MOUSEOVER ->
- Select the conical surface on the green ball joint
(141-F10002_7_1)
as
shown in the image below (not the centerline).
- Select the corresponding conical surface on the yellow knuckle
(141-F10002_5_5_1) as
shown in the image below (not the centerline).
- Press the Apply button to retain this constraint.
Demo Section 6: Add One Final Constraint and Show Degrees of Freedom
- The last constraint is another centerline constraint similar to
the very first one we created above.
(Notice that while the cylindrical surface is highlighted, the
centerline appears. You can now move your mouse over the
centerline to get it to highlight.)
- MOUSEOVER ->
- Select the centerline as displayed in the mouseover image above.
- Select the centerline on the yellow knuckle (141-F10002_5_5_1)
the same way
(as shown in
the mouseover below).
- MOUSEOVER ->
- The constraint will be created and displayed as blue in the image
below
- Press the Apply button to retain this constraint.
- Collapse the Assembly Constraints dialog by clicking on the
header of the dialog
- Load the remaining components of the assembly by selecting the
top level and using RMB-Open, Assembly
- Since the Assembly Constraints dialog is still open, you can grab
the steering arm and dynamically move it to show the remaining degrees
of freedom.
- MOUSEOVER ->
- This concludes this demo.
