Provides access to members that control a representation rule.
Use IRepresentationRule interface to get reference to the individual representation rule objects present in the RepresentationRules collection for a representation class.
Description | ||
---|---|---|
Draw | Draws a layer of a representation rule. If index is -1, all layers are drawn. | |
InsertLayer | Adds a layer to the representation rule. | |
Layer | Layer at a given index. | |
LayerCount | Number of layers in the representation rule. | |
RemoveLayer | Removes a layer from the representation rule. |

RepresentationRule | An object defining a representation rule. |
IRepresentationRule interface provides access to the members of a single representation rule used by a representation class to draw the individual feature representations. A representation rule consists of one or more basic symbol layers namely BasicLineSymbol, BasicFillSymbol and BasicMarkerSymbol. In addition to the symbol layers, a representation rule may also contain geometric effects.
The following code snippet shows how to get access to a RepresentationRule object given with its name. The name of the representation rule can be changed to get access to a different representation rule.
Dim pRepRules As IRepresentationRules
Dim pRepRule As IRepresentationRule
Dim lID As Long, sName As String
Set pRepRules=pRepClass.RepresentationRules
'walk through the representationrules and get a specific rule with given name
pRepRules.Reset
pRepRules.Next lID, pRepRule
Do Until pRepRule Is Nothing
If pRepRules.Name(lID)="Buildings_Rule" Then Exit Do
pRepRules.Next lID, pRepRule
Loop
