Check out the improvements made to rectangular and circular component patterns.
Rectangular Pattern
You can now select a revolved face, cylindrical or conical, to define the direction for a component pattern. The Pattern Component command uses the face axis to define the pattern direction. Use the standard controls to flip the direction.
It is not necessary to activate the selector when using an origin axis, clicking the flyout activates the selector and chooses the selected axis. The direction selection does not change with the activation of the selector, you must also select a new direction.

Circular Pattern
Circular pattern for components is enhanced to provide incremental and fitted positioning methods.
