Use this tab to affect the behavior of the Tangency Constraint (Not Constrained, Constrained by Preceding, Constrained by Following, and Constrained on Both Sides) and Parameter Constraint (Radius, Length, Pass Through Point, etc.) while the alignment is edited.
When an alignment subelement constraint is changed, change the constraints of adjacent elements (preceding, following, or both) to maintain tangency.
Locks the Parameter Constraint of every element in the alignment. The Parameter Constraint property of every row in the Alignment Entities vista is locked.
