Linear
Dimensions (2D) 
Insert 
Dimensions (Sketch/Sheet
Levels)
Use these commands to create 2D linear dimensions at the Sketch and Drawing Sheet Level. At the Drawing Sheet Level, many of the dimension types support each of the four dimension modes (normal, baseline, continuous and ordinate). The default mode is normal. It is used here for documenting purposes. The other modes will vary slightly. Only a subset of these linear dimension types are supported at the Sketch Level.
The required inputs include the points to dimensions and the dimension text location (i.e., origin). Some will request additional reference geometry or values such as lines and angles. See below for the optional inputs.
Insert > Dimensions
> Linear (Sketch/Sheet Levels)
Create a linear horizontal dimension between two points. Select the two points and then drag to locate the dimension text. The figures below indicate the pick points for each dimension mode.
Insert > Dimensions > Linear (Sketch/Sheet
Levels)
Create a linear vertical dimension between two points. Select the two points and then drag to locate the dimension text. The figures below indicate the pick points for each dimension mode.
Insert > Dimensions
> Linear (Sketch/Sheet Levels)
Create a linear aligned dimension between two points.
Select the two points and then drag to locate the dimension text.
Rotated Dimension (2D Sheet
Only)
Insert > Dimensions
> Linear (Sheet Level)
Create a linear rotated dimension between two points.
Select the two points to dimension. Then, enter the angle of rotation
and drag to locate the dimension text.
Projected Dimension (2D Sheet
Only)
Insert > Dimensions > Linear (Sheet Level)
Create a linear dimension between two points and
projected perpendicular to a line. Select the two points to dimension.
Then, select the line to project to and drag to locate the dimension text.
Insert > Dimensions > Linear Offset (Sketch/Sheet
Levels)
Create a linear offset dimension between two parallel
lines. Select the two lines to dimension and then drag to locate the dimension
text.
Projected Distance Dimension
(2D)
Insert > Dimensions
> Linear (Sketch/Sheet Levels)
Create a linear dimension that is the projected
distance from a point perpendicular to a line. Select the line, the point
to dimension to and then drag to locate the dimension text.
Leader Chamfer Dimension (2D
Sheet Only)
Insert > Dimensions > Linear Chamfer (Sheet Level)
Create a linear leader dimension that defines the
length of a line. Only chamfers at a 45 degree angle may be specified.
Select the line and then drag to locate the dimension text.
Aligned Chamfer Dimension
(2D Sheet Only)
Insert > Dimensions > Linear Chamfer (Sheet Level)
Create a linear aligned dimension that defines
the length of a line. Select the line and then drag to locate the dimension
text.
Horz/Vert Chamfer Dimension
(2D Sheet Only)
Insert > Dimensions > Linear Chamfer (Sheet Level)
Create linear horizontal and vertical dimensions
of a line. Select the line and then drag to locate each dimension text.
Select the icon to either center or not center the dimension text between the extension lines. If not center is selected, the dimension location point will also dynamically locate the text.
Auto Dogleg
While the Ordinate Dimension Mode is active, use this option to automatically add a dogleg to the extension line. This is useful when the dimension points are close together.
Text
Use this option to determine how the text of the dimension is generated. Select from the following:
Value - The dimension text will default to the actual dimension value.
User Text - The dimension text defined in the User Text field (see below) is displayed instead of the dimension value.
User Text
Defines the dimension text that is displayed instead of the actual dimension value. Used in conjunction with the User Text option above. Enter the user text in the field provided. You can also right-click in the graphics window to activate the Text and Dimension Editor. It provides additional options for creating special characters and symbols within the text.
Dimension Modes 
See Dimension Modes (2D) for documentation.
