Abstract: A referencing system and method for determining relative distances and locations of three-dimensional objects displayed on a computer generated display, to enable the objects to be connected or otherwise manipulated relative to one another. The system includes one or more nodes or nodes, which upon activation emits radial vectors in any direction in three-dimensional space from a reference point on the node. The vectors project referencing shapes onto the objects, thereby indicating the relative distances and locations of the objects. In one embodiment of the referencing system of the present invention, a referencing shape becomes smaller as the activated node approaches the object onto which the referencing shape is projected.
