centroids or centers of mass. You can create regions from objects that form
closed loops. They area commonly created in order to apply hatching and
shading. (REGION)
relative coordinates Coordinates specified in relation to previous coordinates.
relax constraints Ability to temporarily ignore constraints while editing

tab contains groups of multiple ribbon panels, each belonging to one workflow.
A ribbon panel contains buttons and controls, related to a task.
