25.6 References to Figures

References to objects allow you to quickly select exact geometrical points in existing figures, without having to know the exact coordinates of those points. References to objects can be used to select the end point of a line or arc, the midpoint of a circle, or any other geometrically significant position.

When more than one reference is activated, the closest of all the enabled ones will be displayed.
