Motion-Dimension FB

A Motion-Dimension FB adds the motion-value at its input-connector to a constant we call the Base-Value, to give the total motion-value at its output-connector.

We use the total to control the position of a Motion-Part - a Rocker or a Slider.

Use the Motion-Dimension dialog to:

•edit the value of the constant, *

•optionally, negate

•optionally, negate , the motion-value at the input-connector.

The Motion-Dimension dialog is now open.

Motion-Dimension dialog

The Motion-Dimension (of the Rocker or Slider) = Base-Value(read-write) + (Input) Motion-Value(read-only)

The motion-value at the output-connector is equal to the Motion-Dimension.

Base and Motion Values

Base-Value (read-write)

A constant that you can add to the motion-value at the input-connector.

Motion-Value (read-only)

The motion-value at the input-connector.

Base-Value + Motion-Value (read-write)

Base-Value + Motion-Value = Motion-Dimension at the output-connector.

Directions

Negate Motion-Values

◉ Positive Motion-Values : Motion-Value × 1 ( default )

◉ Negative Motion-Values : Motion-Value × –1

Negate Base-Values

◉ Positive Base-Value : Base-Value × 1 ( default )

◉ Negative Base-Value - Base-Value × –1

Note:

The default positive direction of a:

Rocker is counter-clockwise

Slider is in the direction of the arrowhead on the Slide-Joint. See Positive Direction of Sliders
