A collection of all the RulerLevel objects on the specified ruler. Each RulerLevel object represents the first-line and left indent for text at a particular outline level. This collection always contains five members — one for each of the available outline levels.
Using the RulerLevels Collection
Use the Levels property to return the RulerLevels collection. The following example sets the margins for the five outline levels in body text in the active presentation.
With ActivePresentation.SlideMaster.TextStyles(ppBodyStyle).Ruler
.Levels(1).FirstMargin = 0
.Levels(1).LeftMargin = 40
.Levels(2).FirstMargin = 60
.Levels(2).LeftMargin = 100
.Levels(3).FirstMargin = 120
.Levels(3).LeftMargin = 160
.Levels(4).FirstMargin = 180
.Levels(4).LeftMargin = 220
.Levels(5).FirstMargin = 240
.Levels(5).LeftMargin = 280
End With
