Cuff Design Application UI
The
User Interface Dialog is split in four tabbed pages. Each page has one or more sections with parameters controlling
different portions of the Cuff geometry. The User Interface is arranged as follows:
- Location tab
- Size and Barbs tab
- Boss tab
- Core Pin tab
- Got Thoughts? section
Down below every portion of the User Interface Dialog
is described.
Location tab
The Location tab provides users with two sections that have all needed parameters to locate and orient the Cuff Feature. All this values are referred from an existing CSYS that users must select in order to create the Cuff Feature.
Values
In this section the six degrees of freedom can be defined to orient
and locate the Cuff to its desired position. The parameters found in
this section are consistent and follow the same convention as "Offset from CSYS" method found in the CSYS Constructor
users are familiar with. This is all rotational degrees of freedom are
performed about the X, Y, and Z axes of the Referenced CSYS
correspondingly with the pivot point at the Position dictated by "X Offset", "Y Offset", and "Z Offset" parameters. "X Rotation", "Y Rotation", and "Z Rotation" parameters control rotation about corresponding axes.
Coordinate System
This sections provides a button to select an existing CSYS that will
serve as a parent coordinate system for the Cuff Feature. To select Reference CSYS click the CSYS button. This will prompt the user to pick the CSYS all parameters will refer from. Only CSYS can be selected.

|
NOTE: The Cuff Design Application has
been developed in a way that the Cuff will have a dependence
relationship with the CSYS selected; if the referenced CSYS changes its
position and orientation then the Cuff will be affected as well.
|
|
NOTE: Remember that CSYS are NX objects generated every time a DATUM CSYS is created. CSYS can be identified at the DATUM CSYS origin in blue color showing its actual X,Y, and Z axes. Also be aware that the WCS is not a CSYS object

Size and Barbs tab
The Size and Barbs page has been divided in 2 sections which are
explained
down below.
Size Options
- "Select Cuff
Size". There are three sizes to choose from 5/16in, 3/8in and 1/2in. This option
refers to the size of the tube being connected to the Cuff.
Barbs Options
- "Additional
Barbs". Defines the number of additional barbs. Up to two
barbs can be added.
Boss tab
This page hosts all parameters to control Boss' geometry. Design
Rules have been added to this part of the Cuff Feature to avoid design
problems downstream the Product Development Process. These rules
basically control the minimum radius allowed for the Boss.
Boss Settings
- "Cuff has
Boss?".
Indicates whether or not the Cuff has boss at its base. This is used to
extend the Cuff and yet provide physical stop to the tube.
- "Boss Height".
Input field to specify the height of the boss should the Cuff has it.
This field won't be sensitive if the "Cuff has Boss?"
toggle is off.
- "Boss Dia".
Controls Cuff
Boss diameter. This value can not be minor than the diameter of the Cuff its self. If this rule is not obeyed a message will pup
out; if the
message is ignored an error
will occur
during Cuff creation or update.
- "Cuff Diameter = xx". This is not a parameter its self. This is a dynamic attribute that shows the actual diameter of the Cuff. This value can be referenced when the Boss is used to extend Cuff's height but need to show no Boss at all.
Core Pin tab
The Core Pin tab allows
control over the Pin Tool used to make the Cuff Feature hole. The
setting found in this page provide extended flexibility to not only
create the Cuff's hole but also to affect the component to which the
Cuff Feature is being attached. Below the two sections within this page
are described.
Eccentricity
In this section an eccentricity value can be specified to offset the center of the Pin Tool from the Cuff's center.
- "Along Cuff's X". The Cuff Design Application
creates a CSYS object matching the position and orientation defined
through the Location tab parameters. This CSYS is the one all Cuff
geometry is related to. The Cuff CSYS can be identified in CYAN color
as all wire frame. In some Fuel Pump applications an offset is required
to displace the center of the Core Pin; therefore the Cuff Feature can
be also applied in such situations. The offset value will be apply
along Cuff's CSYS (cyan CSYS).
- "Rotation about Cuff's Z".
Additional to the three rotational degrees of freedom; there is a
fourth rotation allowed. The difference though, is that this last
movement will be performed about Z axis of the CSYS object that results after locating and orienting the Cuff Feature. The final CSYS object can be identified in BLUE color as any other CSYS object. This CSYS Z axis is the one the Cuff CSYS rotates about.

|
NOTE: If the "Rotation about Cuff's Z"is equal to "0" then both CSYS object will overlap and will not be seeing easily. The following picture shows both CSYS. when "Rotation about Cuff's Z" is not "0". Also notice how the profile used to revolve the Cuff is aligned with plane XZ of the cyan CSYS.

Extension Length
In addition to the eccentricity of the
Core Pin; it can also be extended down beyond the Cuff to provide
sufficient solid geometry to affect not only the Cuff body but also
other solid portions of the component being designed.
- "Value" Box. This radio box switch controls how the length of the extension of the Core Pin is managed. There are two options; "Type-in" and "Drag". If "Type-in" is selected a number field to type-in any number greater than 0 becomes available. However if "Drag" is checked the number field deactivates and a scrollbar becomes active; it can be dragged to change length's value. This scroll updates dynamically the curve that defines the Core Pin Tool. Once clicking "OK" or "Apply" the solid geometry will update as well.

Got Thoughts?
This UI section provides
means to get
help. From this section user can invoke a child dialog with a referenced
drawing image that provides quick help by clicking the "Visual Aid" button.
