The Cuff Design
Application
is a Knowledge Fusion Modeling Feature based on
Delphi Best Practices. It creates all the geometry needed to model a
mating interface for convoluted tubes mostly found in Module Reservoir
Assemblies (MRA). This application
groups all
the steps needed in one feature as a
whole:
2D profiles, swept feature operations, detailing features and boolean
operations are all
integrated as one NX modeling feature. All necessary parameters are
allowed to
be modified through the User Interface
Dialog; many other parameters can not be changed since are rule-controlled.
Next are listed the steps to be
followed.
The Knowledge Fusion Cuff Feature is
to be added to any component in need of an interface to attach convoluted tubes to transport fluids.
However users
can create and place the Cuff Feature wherever they want and only must select
an existing Coordinate System (CSYS) to reference location and orientation; all locating parameters are
referenced
from this latter. If no CSYS is defined the application won’t execute. The User Interface
Dialog
has a
button that allows selection of the reference CSYS; selection has
been filtered to allow only selection of CSYS entities from the
Graphics Window.
If no CSYS is selected the "Apply"
and "OK" buttons will be insensitive.
Furthermore if the Cuff Feature is
being executed by
another Knowledge Fusion Application some buttons may be unavailable.
To use the Cuff Design
Application, follow these
steps:

|
Editing an instance
of the Cuff Design Application
is fairly easy and can be treated as any other modeling feature. E.g.
extrude,
revolve, blend, and so forth.
As with any normal
feature there are several ways mentioned
below.
|
Always perform a Make Current Feature over the Cuff feature before changing anything else than Cuff Location parameters ![]() |
Any of the steps
above will open the Cuff Design
Application User Interface
Dialog to edit the selected Cuff instance.
To delete
a Cuff feature follow the same steps as
for deleting any modeling feature in NX.
The Cuff Design Application creates geometry and attributes that defines the Cuff Feature; this is expressions, CSYS, curves, and solids. It also manage which layers the geometry goes to.
Cuff Design Application creates several expressions as any modeling features do. All expressions created have been locked and can not be modified through the Expressions Dialog to prevent any disassociation. Furthermore, it explicitly creates named expressions that can be used to link dimensions of the Cuff to other geometry that may need to update as Cuff instances does. Named expressions created are listed below.

If several Cuff features are created it may not be easy to identify which expressions correspond to which Cuff Feature. The Cuff Design Application has been designed in a way that the index number at the end of the expressions' name matches the index number added to the Cuff Feature name in Part Navigator.

If a Cuff instance is deleted all its expressions will be deleted as well; however, if any expression is been used or referenced by other feature or expression it will be preserved.
Cuff Design Application creates CSYS, curves, and solids.The application controls the default layer geometry goes to.
Cuff Design Feature is a Knowledge Fusion Application that creates a Cuff Mating Connector based on Delphi Best Practices for this type of interfaces. It groups most of the knowledge when it comes to design a Cuff Mating Connector interface. Different options are available in this Knowledge Driven Application so re-use of knowledge and access to it is easier and instant than ever. Cuff design is based on drawings 25338645 (5/16"), 25164799 (3/8") and 25326728 (1/2").

Cuff Design
Feature
has a User Interface Dialog which allows modification of many
parameters. Any
parameter not in the UI means it is not possible to change its value.
There are
several parameters that are application controlled or ruled by design,
engineering or manufacturing.

parameter does click

If during
create or edit of the Cuff you experience
any error please review your settings and correct any invalid input.
There are
mainly two error causes.
If everything seems
to be fine and the error still exists
delete the Cuff and create a new one with the desired options. The Cuff
Design
Application has been developed in such a way that user will get
messages and
errors if some design rules are not followed letting the user know
his/her
misses. However, not all invalid inputs will pop out messages but will make
the
application fail.
In case you are not
able to recover from the error please Report
the Issue or maybe you would like to Request
an Enhancement.
