Break a fixed line into two adjacent fixed lines by creating a point of intersection (PI) at a specified point.
When you select a point (1), the new PI (2) is created. At the new PI, endpoints are created for the new lines, which maintain tangency to one another.
Separate the point of intersection (PI) where the endpoints of two fixed or floating tangents meet.
When you break a PI (1), the tangent endpoints are separated by a specified distance (2). When a PI is broken (3), the second tangent is no longer part of the solved alignment geometry.
A grip is displayed at the point of intersection.
Create a single tangent from two adjacent tangents by removing their point of intersection (PI).
When the PI (1) is deleted (2), the tangent endpoints are removed.
