Auto Constrain
The Auto Constrain tool allows you to apply Geometric Constraints to a selection set of Geometry within the specified tolerance set using the Auto Constrain tab in the Constraint Settings dialogue (click the down arrow as shown below to access this).

- In the Constraint Settings dialogue you can specify the types of Constraints applied, the order in which they are applied, and the applicable Tolerances.

- Once all of the settings are as required, click the Auto Constrain tool, select your Geometry and the Constraints will be applied.

- Note: Fix drawings with minor gaps and overhangs by setting the Tolerance values in Auto Constrain.
