ABSTRACT
Constraints are pre-assembled pieces of code which connect objects in a Scene together, such that they act as a single entity while maintaining individual characteristics. Another way to define Constraints is to say they define relationships between objects. Constraints are applied to objects by going to the Properties window, Constraints buttons, clicking on Add Object Constraint then selecting a Constraint from the menu that displays. Constraints define relationships between objects. The Transformation constraint allows people to control the location, rotation or scale of one object or part of an object by adjusting the location, rotation, or scale of another object. The location, rotation or scale values in either case can be set to operate within a specific range. The Action Constraint allows people to control the action of one object by manipulating the action of another. The Shrinkwrap Constraint could be more aptly named the Mesh Surface Lock.
