AutoConstrain
You can significantly automate the process of applying constraints using the AutoConstrain functionality,
available on the Geometric panel of the Parametric tab. AutoConstrain automatically applies constraints to
geometry that falls within specified tolerances. For example, applying AutoConstrain to a rectangle consisting of
four lines generates the appropriate coincident, horizontal, parallel, and perpendicular constraints to maintain
the rectangular shape through various edits. You can control which constraints are available, in what order they
are applied, and a tolerance to determine whether constraints are automatically applied. These controls are
available on the AutoConstrain tab of the Constraint Settings dialog box, which you can access from the
Parametric tab or using the CONSTRAINTSETTINGS command.
