Intersection tools

The editing intersection tools use analytic geometry to locate and snap the pointer to computed locations, for example, where two overlapping distances intersect. Intersection tools are available on the construction toolbar when you draw a feature using a feature construction tool.

The following diagram illustrates how the intersection tools locate and highlight where specified directions and distances intersect when measured from two known locations shown as points A and B:

The diagram shows the type of geometric relationships the intersection tools can solve.

When ground to grid correction is on, the ground to grid-aware intersection tools compute your input values as ground measurements. An offset angle is applied to directions, and a distance factor multiplies distances. This occurs in real time as you specify construction measurements.

Tool	Description	Ground to grid distance factor	Ground to grid direction offset
Distance Distance	Create a point or vertex where two distances intersect
Direction Distance	Create a point or vertex where a direction and a distance intersect
Direction Direction	Create a point or vertex where two directions intersect
Intersection	Create a point or vertex at an inferred intersection
Midpoint	Create a point or vertex at the midpoint of two locations
