The locations of superelevation critical points are dynamic when you grip edit the alignment geometry and all distances are maintained.
Note: Superelevation data such as slopes and transition lengths are not updated when a curve radius or design speed is changed because those changes make superelevation data invalid. In those situations a warning is displayed and the curve is displayed as “out of date” in the Superelevation Curve Manager. Click Recalculate to recalculate superelevation.
The following illustrations show the dynamic updates:
After grip edits:
