Unconstrained linear dimensioning

Use the Unconstrained Linear Dimension tool to draw dimension lines at any angle. This is different from the Constrained Linear Dimension tool, which constrains dimension lines to the X or Y axis of the plane where the dimension is created. In addition to measuring and dimensioning objects, you can use this tool to calculate the distance between two or more points in the drawing area.

Mode	Description
Unconstrained Linear	Creates a dimension line with a single measurement
Unconstrained Chain	Creates a continuous chain of dimension lines
Unconstrained Baseline	Creates a series of connected dimension lines, starting from an initial base point
Preferences	For Unconstrained Chain mode, specifies whether dimensions are created as a single unconstrained 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)
