We had a call from someone who had become frustrated with trying to change the Primavera P6 Gantt chart gridlines for printout. If you didn?t know, the Gridlines toggle in the print page setup dialog only controls the gridlines of the activity table; and not the Gantt chart. The good news is that Primavera P6 does allow you to change the gridlines of the Gantt chart. Primavera P6 calls these ?sight lines?, and you will have to look elsewhere to find these options; they are not located in the print options. You can learn more here http://ow.ly/KzWlR
