Examples

Copy C#

    foreach (ElementId filterId in view.GetFilters())
    {
        OverrideGraphicSettings overrideSettings = view.GetFilterOverrides(filterId);

        Color lineColor = overrideSettings.CutLineColor;

        if (lineColor == Color.InvalidColorValue)
            continue;

        // Save overrides setting the cut color to green
        if (lineColor.Red == 0xFF && lineColor.Green == 0x00 && lineColor.Blue == 0x00)

    // Make the change to all found filters
    using (Transaction t = new Transaction(doc, "Change override filters"))
    {
        t.Start();

        foreach (ElementId filterId in filterIdsToChange.Keys)
        {

        }
        t.Commit();
    }
}
