Use the Constrained Linear Dimension tool to draw dimension lines that are constrained to the X or Y axis of the plane where the dimension is created. This is different from the Unconstrained Linear Dimension tool, which can draw dimension lines at any angle. In addition to measuring and dimensioning objects, you can use this tool to calculate the horizontal or vertical distance between two or more points in the drawing.
In a 2D view, the dimension line is constrained to be parallel to either the X or Y axis of the active plane. In a 3D view, the dimension line is constrained to the X axis of the plane where it is created, but the plane can have any rotation (similar to the Unconstrained Linear Dimension tool).
If Snap to Working Plane is enabled in the Snapping set on the Status bar, the dimension line is projected to the current working plane, in both 2D and 3D views.

Mode |
Description |
|
Constrained Linear
|
Creates a constrained dimension line with a single measurement |
|
Constrained Chain
|
Creates a continuous chain of constrained dimension lines |
|
Constrained Baseline
|
Creates a series of connected constrained dimension lines, starting from an initial base point |
|
Ordinate
|
Creates a series of constrained ordinate dimensions, starting from an initial base point |
|
Selected Objects
|
Creates a constrained dimension line for the greatest span of a selected object or group of objects |
|
|
For Constrained Chain mode, specifies whether dimensions are created as a single chain object, or as individual dimension objects; also enables collision control, which automatically spaces text blocks so that they do not overlap |
|
Dim Std |
To change the dimension standard for new dimensions created in the document, select a standard from the list; select Custom Standards to create or manage custom dimensions (see Using custom dimension standards) |
The dimension text can be moved. See Editing dimensions.
