Example

C#

private bool LayoutRuleFixedNumberInformation(BeamSystem beamSystem)
{
    //get the layoutRule of the beamsystem
    Autodesk.Revit.DB.LayoutRule layoutRule = beamSystem.LayoutRule;

    string message = "BeamSystem layout rule : " + layoutRule;

    //create a new instance of the LayoutRuleClearSpacing class 
    LayoutRuleFixedNumber myLayoutRuleFixedNumber =
                        new LayoutRuleFixedNumber(8);

    //set the new layoutRule to the beamsystem
    beamSystem.LayoutRule = myLayoutRuleFixedNumber;

    LayoutRuleFixedNumber fixedNumber = beamSystem.LayoutRule as LayoutRuleFixedNumber;

    if (null == fixedNumber)
    {
        return false;
    }
    //try to get the property value of the beamsystem LayoutRule
    int numberOfLines = fixedNumber.NumberOfLines;

    message += "\nNew BeamSystem layout rule: " + fixedNumber;
    message += "\nNew BeamSystem number of beams: " + numberOfLines;

    TaskDialog.Show("Revit",message);

    return true;
}

VB

    Dim myLayoutRuleFixedNumber As New LayoutRuleFixedNumber(8)

    'set the new layoutRule to the beamsystem
    beamSystem.LayoutRule = myLayoutRuleFixedNumber

    Dim fixedNumber As LayoutRuleFixedNumber = TryCast(beamSystem.LayoutRule, LayoutRuleFixedNumber)

    If fixedNumber Is Nothing Then
        Return False
    End If

    Dim numberOfLines As Integer = fixedNumber.NumberOfLines

    message += vbLf & "New BeamSystem layout rule: " & fixedNumber.ToString()
    message += vbLf & "New BeamSystem number of beams: " & numberOfLines
