Use this tab to specify the display of implied points of intersection, where the PI is not defined by two fixed tangents.
By Change in Alignment Direction
Displays alignment PI locations based on incoming and outgoing tangent line elements and a change in the alignment direction.
By Individual Curves and Curve Group
Displays alignment PI locations based on compounding circular curves, or compounding curve group patterns (such as spiral-curve-spiral).
Do Not Display Implied Points of Intersection
Displays only PI locations that were explicitly created by fixed tangents.
