Pick Object < / Pick Vertical < is used to initiate elements for alignment from the current drawing. It is possible to choose one or more lines at a time.
Recalculate All recalculates the geometry and the longitudinal terrain profile of the alignment. The whole alignment will be recalculated and is useful when changing the input data for the current alignment.
OK - Draw draws the alignment in the current drawing with the active Draw Style Configuration, and the Alignment Design function gets closed.
Cancel exits the Alignment Design without saving. All changes made will be lost and the alignment in the database is set back to the earlier version.
