The Motion-Dimension FB

The Motion-Dimension FB dialog-box controls the Base-Value a Motion-Part ; the motion-values at its input-connector control the motion relative to the Base-Value of the Motion-Part.

Thus, when the Motion-Dimension FB does not have a wire at its input-connector, the position of the Motion-Part is specified by the the Base-Value parameter.

Edit Motion-Dimension FB


Edit the Motion-Dimension FB


Open the Motion-Dimension FB dialog-box.

To edit this element from the graphic-area, you can:

1.Double-click the dimension arrowhead


1.Double-click the FB


See How to open a dialog-box, to edit an element


...'CTRL+HOVER+DRAG the dimension arrowhead or dimension line.


Motion-Dimension dialog-box

Parameters to edit:


The position of the Motion-Part when a wire is not connected to the input-connector.

Base-Value + Motion-Value [dimension of the Motion-Part]

This parameter actually edits the Base-Value.

Use it when you want to edit the value as you look at the model to edit the total Va the Motion-Part is a more important design parameter.

Edit the Base-Value to 60.

1.Click the bottom, left & right arrows, at the right of the data-box, to make sure the Spin-Increment is 10.
2.Right-click the Base-Value data-box

The 'Zero / Round' contextual-menu shows next to your pointer.

3.Click 'Round'.

The dimension 'rounds' up or down to the nearest number that is exactly divisible by the Spin-Increment.

In the example to the left, the Base-Value dimension is 47.827°. The Spin-Increment is 10.  The dimension will round up to 50°.

4.Click the top,  right arrows, at the right of the data-box, to increase Base-Values to 60°.
