I am trying to arrange the FK caption/name in the ER diagram. Is there any option to arrange the names/caption in the middle of the Parent child entity. Please find the attached screen snap for quick reference. Highlighted in blue.
there is no any specific option to arrange caption/name of relationships into the middle of the parent and child entity but you can align them by the commands from the alignment toolbar. Place the one of your caption/name to the desired position in the middle of line, select it as first, select the rest of captions/names by the SHIFT+ left mouse click and click e.g. Align horizontal center. All captions/names should be centred.
