The Measurement FB measures a dimension for a machinecycle. •There are two outputconnectors for a measurement between two Points  see more below. •There is one outputconnector for a measurement between other sketchelements. The motionvalues at the outputconnectors include the dimension, and its first and second rateofchange. 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 CADLine. You can also dimension between a sketchelement and the Xaxis or Yaxis of a Part. 
Add : 
STEP 1: Add a Measurement FB
The Measurement FB and Dimension show in the graphicarea. 

Uses : 
Connect a wire from the outputconnector of a Measurement FB to the inputconnector of a:

Measurement FB between two Points 
STEP 2: Click in the graphicarea the sketchelement, or the sketchelements, that you want to measure STEP 3: Click in the graphicarea to place the Measurement FB. The Measurement FB is near to the dimension. •To move the Measurement FB: DRAG the FB •To move the Measurement Dimension: CTRL+DRAG the FB or the Measurement Dimension. In this image: The dimension is between two Points The Measurement FB has two outputconnectors when it measures between two Points The Measurement FB has one outputconnector when it measures other sketchelements. See details below for motionvalues available from the outputconnectors. 
•Length of Line; Radius of a Circle or Arc •Distance between two Points •Perpendicular Distance between a Point and a Line

Two Parallel Lines. NOT RECOMMENDED 
The Measurement FB may measure the angle between the lines as 0º, 360º or 180º. See: Angle Measurement between Two Lines, and Perpendicular Distance between Line and Point. 

Point and Point 
Linear Distance and Angle between two Points. 1.Click the Point 2.Click the Line The Measurement FB has two outputconnectors: •Top outputconnector: the lineardistance, and its first and second motionderivatives •Bottom outputconnector: the angle, and its first and second motionderivatives 

Point and a Line 
Perpendicular Distance 1.Click the Point 2.Click the Line Note: You many need to add a Line to a Part in the PartEditor. To measure a Horizontal Distance or Vertical Distance: click the Xaxis or Yaxis as the Line. 
Measurement: Angle between Three Points  Internal Angle and External Angle.

Add Angle Dimensions between two Lines

After you select the two Lines, and before you click in the graphicarea to place the Measurement Dimension and FB, you can display one of eight angles. Move your mousepointer around the apex of the two lines: CASE 1: Mouse Pointer moves Counterclockwise : 4 angles < 180° : the Acute, Obtuse, Supplementary and Vertical angles CASE 2: MousePoint moves Clockwise : 4 angles > 180° : the reflex angles  or the angles that are opposite to those angles of CASE 1.
