Motion-Path FB

Motion-Path FB :	A FB that adds a Motion-Point to a sketch-path - see sketch-loop
Motion-Point :	The motion-values at the input to the Motion-Path FB control the motion of the Motion-Point along the sketch-path.

To control the motion of a robot along a sketch-path

To control the motion of a chain or belt along a sketch-path

To control the motion of an extending-cylinder to raise a Scissor-Lift

What to do:

STEP 1: Start the Add Motion-Path FB command

1.Click Kinematics FB toolbar > Motion-Path FB

1.Click Add menu > Add Motion-Path FB

The Command-Manager has one selection-box.

2.Click a sketch-element from a sketch-path

The Motion-Path FB is now in the graphic-area (and Assembly-Tree).

AND

A Motion-Point is at the start-Point of the sketch-element you click on the sketch-path.

STEP 2: Open the Motion-Path dialog

1.Double-click a Motion-Path FB in the graphic-area

The Motion-Path dialog is now open.

Dialog :

Function-Block	Motion-Path FB	Motion-Dimension FB
Motion Element	Motion-Point	Motion-Part
Constraint	sketch-path	Joint
Input	Motion-data at input-connector	Motion-data at its input-connector
SUMMARY	Motion-Point is constrained by a sketch-element and motion-data controls its position, velocity, and acceleration	A Motion-Part is constrained by a joint and motion-data controls its position, velocity, and acceleration.
