The Set Reference Tool is used to indicate which performer(s) will be used as a reference point for adjusting or cleaning drill. To set a performer as a reference point, select the Set Reference Tool from the Tool Palette.
Highlight a group of performers and select the Set Reference Tool. The Set Reference Tool control panel will open, and you may click on performers to set them as reference points. There is no limit to the number of reference point performers allowed.
Reference points will be displayed on the chart with a diamond around them, and their coordinate will be underlined on coordinate sheet print outs.
