Motion-Path FB :

A function-block to add a Motion-Point to a sketch-path. An input to the Motion-Path FB can control the motion of the Motion-Point along the sketch-path.

The Motion-Path FB calculates, and can also control the length of the sketch-path (belt). You can edit the Tooth-Pitch of the Belt.

Motion-Point :

A Point that we constrain to move along a sketch-path.

sketch-path :

A sketch we add to a Part to control the path of the Belt. It is usually a closed sketch-path (also called a sketch-loop). However, it can also be an open sketch-path - see sketch-path

Driving-Pulley :

The motion of a Driving-Pulley controls the motion of the Belt.

You can a minimum of zero(0), and a maximum of one(1) Driving-Pulley to each Belt.

It is a Pulley you add to a rotating-Part that is kinematically-defined before you do Add Pulley.

Driven-Pulley :

The motion of a Belt controls the motion of a Driven-Pulley.

The maximum number of Driven-Pulleys is equal to the number of arcs along the sketch-loop, that defines the path of a Belt (–1 Arc if you also add a Driving-Pulley).

A Pulley that you add to a rotating-Part that is not kinematically-defined before you do Add Pulley.

Belt :

We use the derived-name of Belt for the sketch-path when we relate the motion of a Motion-Point along the sketch-path to the motion of one or more Pulleys.

Belt Tooth Pitch :

The distance between each tooth on a Belt.
