Point-Data FB

Summary of Point-Data FB

GA-FB-PointData

Use to Point-Data FB to get a motion-values of a Point

The Point must be a child to a kinematically-defined Part.

The Point-Data FB has three output-connectors.

Its three output-connectors give, with respect to the Mechanism Plane, the Point's:

➔	X–axis motion-values

➔	Y–axis motion-values

➔	Magnitude of the Point's motion-values

The magnitude of the motion-values are equal to:

o	√(X2 + Y2)

Add and Edit Motion-Path FB

Toolbar:

Kinematic-FB toolbar > Add Point-Data Function-Block (FB)

Command:

Add menu > Add Point Data Function-Block (FB)

STEP 1: Add the Point-Data Function-Block

1.	Click the Point-Data FB in the Modelling FB Toolbar.

2.	Click again in the graphic-area to 'place' the Point-Data FB in the graphic-area.

The Point-Data FB is now in the graphic-area.

STEP 2: Open the Point-Data Function-Block

1.	Click the Point-Data FB in the graphic-area or Assembly-Tree one time

The Point-Data FB should be in the Selection-Window

2.	Right-click the Point-Data FB In the Selection-Window

3.	Click 'Edit element...' in the contextual-menu.

1.	Double-click a Point-Data FB in the Assembly-Tree

Dialog-13.2-PointDataFB-selected

STEP 3: Select a Point to the selection-box

1.	Click a Point in the graphic-area.

If the incorrect Point is in the selection-box, then:

1.	Click a different Point in the graphic-area.

The Point will now be in the selection-box.

STEP 4: Close the Point-Data Function-Block

1.	Click the to close the Point-Data FB.

How to Use:

You can connect wires from the Point-Data FB:

1.	To a Graph FB, to plot the motion-values of Position, Velocity and Acceleration of the Point in the X and Y–axis directions.

2.	To replace the Linear-Motion FB. as the input to another Motion FB

Notes:

Top-Tip

To plot the X or Y position, velocity and acceleration of a Point in the same graph.

1.	Drag a wire from the same output-connector of the Point-Data FB three times to three different input-connectors of one Graph FB,

2.	Use the Y–axis display options in the Graph dialog-box to display all motion derivatives.
