Motion-Dimension FB

A Motion-Dimension FB identifies a Part you want to move with a motion, which we call a Motion-Part.

A Motion-Dimension FB may specify the:

•	Angle of a Rocker

- or -

•	Position of a Slider

There are two different Motion-Dimension FB icons in the graphic-area that are different to the icon that is in the Kinematics FB toolbar.

The FB icons in the graphic-area are:

	Motion-Dimension FB for a Rocker
	Motion-Dimension FB for a Slider

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

Dialog-13.2-Motion-DimensionFB

Base-Value: in the dialog to the left the Base-Value = 75

This is the 'constant' contribution to the Motion-Dimension

Motion-Value: (read-only) in the dialog the Motion-Value = 9.159921

The 'motion' contribution to the Motion-Dimension.

It is the motion-value 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
