Use Add Dimension to add all Linear and Angular Dimensions:
•Length of a Line ; Radius of a Circle or Arc.
•Perpendicular Distance from a Line, or XAxis, or Yaxis, to a Point
•Angle between two Lines, or the Angle from the Xaxis or Yaxis to a Line
•Angle between three Points.

To Add a Dimension:
The Dimension is now in the graphicarea. 

Notes: •When sketchelements are fully defined, you cannot add any more dimensions or constraints. •You cannot add a drivendimension in the PartEditor. Alternatively, use add Measurement FB in the MechanismEditor as a drivendimension. •Generally, do not make a dimension zero. It is better to add a constraint to move Lines or Points together. See SketchConstraints 
1.Deselect all other commands 2.Doubleclick the arrowhead of a dimension element Why the arrowhead? •MechDesigner does NOT respond if you click the Dimension Number •It is easier to click the arrowhead than to click the dimensionlines or extensionlines. 
There are two methods you can use to locate a Point* in a Part. NOTE: These two methods relate to a Point sketchelement, and a startPoint, endPoint and centrePoint in other sketchelements. Method 1: Add Dimensions
Method 2: Lock & Specify in the Point Properties dialogbox Note: You can use Method 2 only if you have NOT added to the Point a dimension or a constraint.

SelectionWindow / GeometryTree 

•Length of a Line

1.Click the Line 
Dimn 

•Distance between two parallel Lines •Distance from Yaxis(or Xaxis) to and Vertical (or Horizontal) Line

1.Click a Point at the one end of the Line 2.Click the other Line (or axis). 
DimLtoLn 

•Shortest distance between two Points Note: Arcs, Circles, and Lines have Points. 
1.Click each Point 
DimPtoPn 

•Horizontal Distance between two Points 
1.Add a Vertical Line from one of the Points 2.Click the Point and then the Vertical Line 


•Vertical Distance between Points 
1.Add a Horizontal Line from one of the Points 2.Click the Point then the Horizontal Line. 


•Shortest distance between a Point and a Line (or axis). Note: Arcs, Circles, and Lines have Points. 
1.Click the Point then the Line (or axis).

In SelectionWindow as: 

•Radius of a Circle

•Click the Circumference of a Circle

Example 
Dimension: 
How? 
In SelectionWindow as: 

•Angle between three Points 
•Click the Point that will form the apex of the angle, followed by the other two Points. 
DimAngPPPn 

•Angle between two Lines •Angle between an axis and a Line The Lines do not need to cross. 
•Click each Line The displayed angle has rules. See Below

DimAngLtoLn 

Angle between two Lines  Rules: The dimension shows next to your pointer when you select two Lines. Before you click your mouse again to define the displayed angle, you can select which angle to display. There are eight possible angle dimensions: •Move your mouse counterclockwise around the apex of the two Lines, the 'acute', 'obtuse', 'supplementary', or the 'vertical' angle <180° will show. •Move your mouse clockwise around the apex of the two Lines, and the 'reflex' angles to the other angles will show.
