Use Add Dimension to define the Length or Radius of a sketchelement, or the Distance, or the Angle between sketchelements.
You can also define the Distance, or an Angle, between the Xaxis or Yaxis and a sketchelement.
Note: You can rename the Dimension in the Dimension dialog.
See below How to add dimensions
Toolbar : 
PartEditor : Geometry toolbar 

Menu : 
PartEditor : Add menu > Geometry submenu> > Add Dimension 

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



Notes: •When sketchelements are fully defined, you cannot add a drivendimension. You can add Measurement FB in the MechanismEditor as a drivendimension. •Generally, do not make a dimension zero. It is better to add a constraint (See SketchConstraints toolbar) to move Lines or Points together.

1.Deselect all other commands 2.Doubleclick the arrowhead of a dimension element Why the 'arrowhead'? MechDesigner will not respond if you click the Dimension Number And, simply, it is more difficult to click the dimensionlines or extensionlines. 
Locate a Point in a Part in one of two ways:

Lock & Specify in the Point Vector and Location dialog box

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 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. 


•Perpendicular 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).

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.
