AccuSnap and the Near Snap Point
When working with this snap mode, manually, you move the pointer to the position that you want the snap to be located and then enter a tentative snap point, followed by a data point to accept the location. If the location is incorrect, you move the pointer along the element and enter another tentative snap point.
With AccuSnap, as you move the pointer to the required element, it highlights and the proposed tentative snap point marker displays. To position the "nearest" snap point, you simply move the pointer along the highlighted element, until the required location is reached, and enter a data point.
