Use Add Dimension to add a Linear or Angular Dimension to or between sketchelements.
Dimensions include the:
•Distance between Points*
•Length of a Line** ; Radius of a Circle or Arc.
•Perpendicular (shortest) Distance from a Point* to a Line**, Xaxis, or Yaxis.
•Angle between two Lines, or the Angle from the Xaxis or Yaxis to a Line**
•Angle between three Points*
* Point, startPoint, endPoint, and centerPoint.
** Line or CADLine
Notes:
Usually, do not make a dimension zero. It is better to add a constraint. See SketchConstraints
See How to add dimensions, How to edit a dimension.
See also: NumberFormat: Precision and Digits, Dimension Font Size
To Add a Dimension:
The Dimension is now in the graphicarea. 
1.Disable all other commands 2.Doubleclick the arrowhead of a dimensionline Why the arrowhead? •simply, it is easier to click the arrowhead than the dimensionline or extensionline. AND •nothing happens if you click the dimensionnumber 
* Point, startPoint, endPoint, and centerPoint.
** Line or CADLine
There are two methods to locate a Point. Method 1: Add Dimensions
Method 2: Use the Point Properties dialog This method is possible: •only with a Point sketchelement It is not possible with a startPoint, centerPoint, centerPoint AND •not possible if the Point has a dimension or constraint

•Length of a Line**

1.Click the Line** 
Dimn 

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

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

•Shortest distance between two 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)

1.Click the Point* then the Line** (or axis).

Example 
Dimension: 
How? 
In SelectionWindow as: 

•Radius of a Circle

•Click the Circumference of a Circle 
DimRadiusn 

•Radius of an Arc 
•Click the Radius of an Arc 
DimRadiusn 
Example 
Dimension: 
How? 
In SelectionWindow as: 


•Angle between three Points*

•Click the Point* that is the apex of the angle, followed by the other two Points*. The angle is the clockwise angle from the second Point* to the third Point* you click. 
DimAngPPPn 

•Angle between two Lines** •Angle between an axis and a Line** The Lines** do not need to cross. 
•Click each Line** The angle that we display for you has rules. See RULES, below

DimAngLtoLn 

RULES: There are eight possible angle dimensions:
