Chapter 6. Accuracy in Creating Drawings... > From and Apparent Intersection Osnap...

From and Apparent Intersection Osnaps

Much like the Object Snap Tracking feature, the “auxiliary” Osnaps From and Apparent Intersection supply data points that stand in some relationship to points on drawing objects. The From object snap establishes a temporary reference point as a basis for specifying subsequent points. The From object snap is normally used in combination with other object snaps and relative coordinates. For example, at a prompt for the center point of an arc, you could type From Endp , select a line, and then type @4,5 to locate a point four units to the right and five units up from the endpoint of the selected line. The center of the arc would then be located at this point.

Apparent Intersection snaps to the apparent intersection of two objects that might or might not actually intersect in 3D space. In 2D drafting, Apparent Intersection is usually involved with the projected intersection of two line elements.
