How to Add: 
The Measurement FB and the measurement between the sketchelements show in the graphicarea. * You can also click the Xaxis or Yaxis of a Part as a 'Line'. 

How to Use: 
In the Mechanism Editor: measure the length*, radius*, distance or angle between sketchelements in the same or different Parts. * These would be fixed dimensions and not very useful to know. You can connect the outputconnector(s):
Note: For options 2 and 3: you will see a message in the Feedback area: '1 Mechanism dependencies detected'. You should rebuild the model when the number of dependencies becomes more than 1 if the data is critical, before you use the data for a Cam, for example.

The Measurement FB is at the BasePart. You can drag the FB to a more convenient location. In this example: 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 you measure between any other sketchelements. See details below for motionvalues available from the outputconnectors.

A Line or CADLine. A Circle or Arc. 
Length: The length of the Line! Radius: The radius of the circle or arc. 

Two Parallel Lines.

It is often difficult to measure the distance between two parallel lines. The Measurement FB will often return the angle between the lines as 0º, 360º or 180º. See Also: Angle Measurement between Two Lines, and Distance between Line and Point. 

Two Points 
Distance between two Points. The Measurement FB has two outputconnectors:


A Point and a Line 
Perpendicular Distance between a Line and a Point. Select the Point first, then the Line. You many need to add a Line to a Part in the PartEditor. To measure a 'Horizontal Distance' or a 'Vertical Distance' you may need to add a Line to a Part in the PartEditor. 
My workaround when two Points are at one Point, but I want to add a measurement with the Point at the apex of an angle.
When you do this, the angle is not yet giving the angle you actually want.
Now, the angle is the angle you want. Measurement: Angle between Three Points In the graphicarea:
Point '1' is the 'apex' of the angle.
The Measurement FB displays the counterclockwise angle from Point '2' to Point '3'.

Measurement: Angle between Two Lines 


After you select the two Lines, and before you click in the graphicarea to place the dimension, you can move you mouse around the apex of the angle to control which angle to display. There are eight possible angles: If you move your mouse pointer 'counterclockwise' around the apex of the two Lines, MechDesigner shows:
