The Parameter Wiring dialog allows you to define the relationships for
Wire
Parameters
on page 3322. In this dialog, you can create new one and two-way
control relationships between object parameters, edit existing relationships,
and create or edit expressions which 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 on
page 2636 and
Custom Attributes on page 329 to objects, materials, and modifiers.
NOTE Parameter Wiring is a modeless dialog on page 8045, and you can have several
dialogs open at the same time.
Procedures
Example: To use an expression with wire parameters:
1 Create a box and a sphere in your scene.
2 Right-click the box, and from the quad menu choose Transform quadrant
> Wire Parameters.
3 From the pop-up menu, choose Object (Box) > Length.
A rubber-band dashed line now connects the box and the mouse cursor.
4 Click the sphere and choose Transform > Position > 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 Wiring dialog, create a one-way wire by clicking the
arrow pointing toward the box’s tree view.
6 Type 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 viewport.
Note that as the sphere moves in the viewport, the length of the box
changes. Using abs() ensures that the box never has a negative length.
