### Measurement Function-Blocks

 The Measurement FB measures a dimension for a machine-cycle. •There are two output-connectors for a measurement between two Points - see more below. •There is one output-connector for a measurement between other sketch-elements. The motion-values at the output-connectors include the dimension, and its first and second rate-of-change. You can measure: •Length of a Line , Radius of a Circle •Distance between: two Points, a Line* and a Point, two parallel Lines* •Angle between: two Points, two Lines*, three Points. *A Line and CAD-Line. You can also dimension between a sketch-element and the X-axis or Y-axis of a Part.

STEP 1: Add a Measurement FB

 1.Click Kinematics FB toolbar > Measurement FB or 1.Click Add menu > Measurement FB 2.Click a sketch-element, or sketch-elements between which you want to measure. 3.Click the graphic-area.

The Measurement FB and Dimension show in the graphic-area.

Uses :

Connect a wire from the output-connector of a Measurement FB to the input-connector of a:

 •Motion-Dimension FB or Motion-Path FB - the motion-values at the output of the Measurement FB become the motion input for a Motion-Part or Motion-Point •Motion FB -  the motion-values at the output of the Measurement FB become the X-axis for the Motion, and the output from the Motion FB will be the Y-axis of the Motion Note: Message in the Feedback-Area may be: '1 Mechanism dependencies detected'. This means, that the motion of a kinematic-chain is a function of (dependent on) the motion of a different kinematic-chain.
