Use the Add Story -- Keep Existing Story Elevations form to specify the elevation where a story is to be added to the model.
The elevation specified is for the top of the story.
If the elevation specified for the added story is below the elevation of the existing top story, the program splits the specified height between the top story and the to-be-added story; these heights can then be readjusted as needed.
The Add Story - Keep Existing Story Heights form can be used to add story data based on specifying the height instead of the elevation of the added story.
