# Arc Arc Intersect

Description

Locates the coordinates of the point (n) at the intersection of two arcs. The point's coordinates are defined by the intersection of the arc centered at pCC1 with radius r1 and the arc centered at pCC2 with radius r2.

The intersection is that point closest to a specified point (pID), if pID is positive, or that point farthest away from the specified point (pID), if pID is negative. You can compute all of the intersection points by not specifying pID (that is, entering 0).

Syntax

arc arc intersect n pCC1 {r1} pCC2 {r2} pID /!fnam /*description

• n is the new point at the intersection of two arcs.

• pCC1 is the center of the first arc.

• r1 is the radius of the first arc.

• pCC2 is the center of the second arc.

• r2 is the radius of the second arc.

• pID is a point used to determine which solution to use.

• fnam is a preference name that corresponds to a point preference defined in the civil.xin file.

• *description is a description that can be assigned to each point. The `*' is required.
