Regression Points

Regression points can be created using multiple tools; from survey points, line strings and rails. They storepoint information(including elevation), regression properties, slew and lift/lower values, existing cant (if created from rails), unacceptable slew and maximum lift/lower values.

Horizontal and vertical regression points are synchronized and changing one will update the other. Vertical regression points are created automatically as horizontal geometry is created.

Regression points must be in the same file as the regression analysis is done. As changing geometry updates the slew values which is stored on the regression points, and points can only be updated when they are in an active model (not in a reference model).
