The Unconstrained Dimension tool can draw dimension lines at any angle. Along with measuring and dimensioning an object, use this tool to calculate the distance between two or more points in the drawing area.
Unconstrained Chain mode creates a series of connected dimension lines, with each line segment displaying its specific measurements. Use the Chain Dimension preferences option on the Tool bar to set whether to create multiple dimension objects or a single chain object.
When dimensions are part of a chain object, they can all be moved at once, and their attributes and properties can be changed as a group. The properties of dimensions in a chain object also can be edited individually. When dimensions in the chain are modified, the other dimensions adjust automatically. See
Modifying Dimensions for more information about editing chain objects.
