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

Edit the Motion-Dimension FB

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:

Icon-FB-MotDim-Rocker

Motion-Dimension FB for a Rocker

Icon-FB-MotDim-Slider

Motion-Dimension FB for a Slider

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

- or -

Motion-Dimension FB dialog-box

Dialog-13.2-Motion-DimensionFB

1s-red Base-Value: in the dialog to the left the Base-Value = 75

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

2s 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.

2s 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
