= SUMMARY =

Traditionally, to rotate your model locally on all three axes you would have to create a hierarchy made up of three nulls. Each null would then have to represent the three different axes (Null 1 parent of Null 2, and so on, with the target model as the child at the bottom of the hierarchy).

An alternate method, that is quicker and more economical, is to position and orientation constrain (Constraint > Position and Constraint > Orientation) the target model to a 1 joint IK chain`s root Null.

Then, rotate the IK chain`s joint on any axis (while in ADD mode). The target model will now behave as if its rotations are local.
