Parameter Wiring Dialog 395
A pop-up menu displays the parameters to
which you can link.
5. Choose the p arameter you want to link f rom
the displayed menu.
The
Parameter Wiring dialog (page 2–395)
opens.
6. Choose the desired parameters in the dia log ,
and click the direction buttons between the
twopanelstodeterminethecontroldirection:
one way or both directions (changes to either
object’s selected parameters affect the other
object).
7. Click Connect to complete the wiring.

The Parameter Wiring dialog allows you to define
the relationships for
Wire Parameters (page
2–393)
. In this dialog, you can create new one
and two-way control relationships between object
parameters, edit existing relationships, and create
or edit expressions w hich define the parameter
relationships.
Only parameters that can be animated can be
wired. Sub-objects, such as vertices, must be
animated before they can be wired.
Parameter wires can be used to establish
connections from
Manipulators (page 2–26)
and Custom Att ributes (page 1–124) to objects,
materials, and modifiers.
Note: Parameter Wiring is a modeless dialog (page
3–1067)
, and you can have several dialogs open at
thesametime.
Procedures
To use an expression with wire parameters:
1.
Create a box and a sphere in your scene.
2. Right-click the box, and f rom the quad menu
choose Transform quadrant > Wire Parameters.
3. From the pop-up menu, choose Object (Box)
>Length.
4. Click the sphere and choose Transform >
P osition > Z Position from the pop-up menu.
The position of the sphere and the length of the
box are now wired.
5. In the Parameter Wir ing dialog , create a
one-way wire by selecting the ar row pointing
toward the box’s Tree V iew.
6. Ty pe abs ( before Z_position, followed by a
closing parenthesis, ), in the expression text
box for Box01, so that the entire expressions is
abs(Z_Position) .
7. Click Connect.
8. Move the sphere upward along the Z axis in the
view por t.
Notethatasthespheremovesintheviewport,
the length of the box changes. Using abs()
ensures that the box never has a negative length.

2. Choose the master parameter in the t ree view.
3. Choose the first slave parameter in the other
tree view.
