Measurement FB

Use a Measurement FB to measure a Dimension.

You can measure the:

Length of a Line, CAD-Line

Radius of a Circle, arc

Distance between two Points**

Distance between a Line* and a Point**

Distance between two parallel Lines*

Angle between two Lines*

Angle between three Points**

* Line, CAD-Line, X-axis, Y-axis.

** Point, start-Point, end-Point, center-Point, and Motion-Point.

The motion-values at the output-connector(s) of a Measurement FB.

The measurement is usually between sketch-elements that are in different Parts. Thus, the dimension changes throughout the machine-cycle.

The motion-values at the output-connector(s)§ s of a Measurement FB:

are a function of the Master-Machine-Angle

include the continually changing dimension

include the first and second motion-derivative of the dimension.

§ There are two(2) output-connectors when you measure the distance between two Points* - see more details below

Connect wires from the output-connectors of a Measurement FB

You can connect wires from a Measurement FB to a:

Graph FB or Stats FB - to analyze the dimension and motion-values

Motion-Dimension FB or  - to use the output as the motion-values for a Motion-Part.

Motion-Path FB - to use the output as the motion-values for a Motion-Point.

Motion FB - to use the motion-values as the X-axis of a Motion design in MotionDesigner.

Math FB - to use the motion-values in an equation, or to change the units of the motion-values.


Messages 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 (measurement) of a different kinematic-chain. It is usually called Motion-Dependency.

1.Click Kinematics FB toolbar > Measurement FB


1.Click Add menu > Measurement FB

2.Click a sketch-element or the sketch-elements between which you want to measure.

In this example, the Measurement FBRed-14-1 and DimensionRed-14-2 is between two PointsRed-14-3Red-14-4

3.Click the graphic-area.

The Measurement FBRed-14-1b and DimensionRed-14-2 are now in the graphic-area.


In the graphic-area, to move the:
