Motion-Dimension FB

A Motion-Dimension FB

•	identifies a Part (Motion-Part) you want to move with motion-values.

•	specifies its starting-position

•	specifies its positive direction for increasing motion-values

When the Motion-Dimension FB specifies the:

Angular Position of Part, it is a Rocker
	<< the Motion-Dimension FB in the graphic-area

When the Motion-Dimension FB specifies the:

Linear Position of a Part, it is a Slider
	<< the Motion-Dimension FB in the graphic-area

Edit the Motion-Dimension FB:

1.	Double-click the Motion-Dimension FB in the graphic-area or Assembly-Tree

- or -

1.	See How to Open a Dialog-Box

The Motion-Dimension dialog-box is now open.

The Motion-Dimension FB function is:

Output = Input + Base-Value

Dialog-13.2-Motion-DimensionFB

Base-Value:

The 'constant' contribution to the Motion-Dimension

Motion-Value: (read-only)

The 'motion' contribution to the Motion-Dimension at the input-connector to the Motion-Dimension FB.

Base-Value + Motion-Value

∑ Base-Value + Motion-Value = Motion-Dimension

∑ 74 + 91.559104 = 84.159921

Note: Units are determined by the data-type at the input-connector

Directions

Note: I generally do not use Directions - I prefer to arrange the model so that I can predict the positive 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

Notes:

The Positive direction of a Motion-Dimension:

Rocker - counter-clockwise angle

Slider - direction of arrowhead on Slide-Joint - See Positive Direction of Sliders
