A couple of things have come to mind trying to use the dialog to explain how OR is calculating drag on a recent rocket:

1. when a row in the dialog is clicked, the corresponding component in the rocket design should be highlighted.
2. a fifth column should be added to the drag tab, giving the aggregate total Cd for each component. The current fourth column, showing per instance total Cd, should be retained. The grand total Cd should be over this fifth column.
