Project sightlines can be turned on or off by toggling the checkbox next to the sightline(s) you want to turn on or off. Below is a brief description of what each of the sightlines settings are for:

• Project Start Date: This includes both the vertical line marking the project start date, as well as the text "Project Start Date" which appears next to it. The color for both is set by using the color picker.
• Data Date: The data date is the date that the schedule should be up-to-date with from the last update. This setting includes the vertical line marking the data date, the text "Data Date" which appears next to it, and, when in Update Mode, includes the update net as well that spans from the current data date to the new proposed data date for that update. Turning the data date off will also turn off display of these other features. The color for all three features is set by using the color picker.
• Major/Minor Sightlines: Major and minor sightlines function in the same manner. They act as visual guides that mark a particular repeating interval of time. If enabled, their appearance can be configured by selecting one of the following line styles: Solid, Dotted, Short Dash, Long Dash, or Dot Dash. The major and minor sightlines can be set to repeat at any of the following lengths of time: Days, Weeks, Months, or Years. If, for example, you set either of the major or minor sightlines to repeat every three months, you will have four sightlines for every year at a quarterly interval.
