Basic Relationships: Constraints
As you know, Maya is all about the relationships between object nodes. You can create animation on one object based on the animation of another object by setting up a relationship between the objects. The simplest way to do that (outside of grouping) is to create a constraint. For example, you can “glue” one object to another’s position or rotation through a constraint.
A constraint creates a direct relationship between the source and the target object’s Translate or Rotate attributes. This section explores six types of constraints: point, orient, scale, aim, geometry, and normal.
The Point Constraint
To attach a source object to a target object but have the source follow only the position of the target, use a ...
