This tool is written to improve the efficiency of constrainting.

Find Joint via vertex : Select the smooth bind joint via current selected vertex.

 parent constraint : Parent constraint the second selection with the first selection with auto skipping the locked attributes.

parentConstraint Parent : Parent constraint the parent hierarchy of the section selection with the first selection.

Constraint Lister.. : Load constraint lister to manager the constraint issues of the constraint object.

Anim Constraint : Create a locator ,whose parent hierarchy will be parent constrainted by the first selection ,and the locator itself will constraint  the  second selection. Therefore the first selection is controlling the second selection and meanwhile u can use the locator to tweak and keyframe the position of the second constrainted object.

Point/Orient/Aim Constraint: Point / Orient / Aim constraint the second selection with first selection with auto skipping the locked attributes.

Clear Constraint : Clear the selected constrainted object 's constraint.

Modify Constraint Axis : Modify the constraint axis of the selected constrainted object.

Correct weight name: Correct the constraint weight attribute name.

Export/Import constraint offset.. :Export / import constraint offset information.

Clear offsetFile..: Delete all constraint offset file exported before in the Maya temp folder .

The buttons from top to bottom :

The first button: Similar to MGtools icon in MGtools UI. It is used to manage the bar itself. Click it to minimize / restore Shelf bar.

Find Joint via vertex button  : Select the smooth bind joint via current selected vertex.

Constraint Lister button : Load constraint lister to manager the constraint issues of the constraint object.

Anim Constraint button : Create a locator ,whose parent hierarchy will be parent constrainted by the first selection ,and the locator itself will constraint  the  second selection. Therefore the first selection is controlling the second selection and meanwhile u can use the locator to tweak and keyframe the position of the second constrainted object.

parent / point / Orient / Aim constraint：Parent / Point / Orient / Aim constraint the second selection with first selection with auto skipping the locked attributes.

Tips : Right mouse button clicking on the constraint button:

constraint parent: Parent / Point / Orient / Aim constraint  the parent object of the section selection with first selection.

Option: Open maya default respective constraint options.
