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

Dimension Standards

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)
