Remarks

This filter is a quick filter. Quick filters operate only on the ElementRecord, a low-memory class which has a limited interface to read element properties. Elements which are rejected by a quick filter will not be expanded in memory.

Example

// Create an ElementDesignOption filter to find all walls in the active design option.
// Note that if no design option is being edited, GetActiveDesignOptionId() method will return ElementId.InvalidElementId,
// ElementDesignOptionFilter with invalid id will filter elements not associated to a design option
ElementId activeOptId = Autodesk.Revit.DB.DesignOption.GetActiveDesignOptionId(document);

// Create an ElementDesignOption filter
ElementDesignOptionFilter filter = new ElementDesignOptionFilter(activeOptId);

// Apply the filter to the elements in the active document,
// use shortcut method OfClass() to find Walls only
FilteredElementCollector collector = new FilteredElementCollector(document);
ICollection<Element> wallsOfDesignOpt = collector.WherePasses(filter).OfClass(typeof(Wall)).ToElements();

// Find all walls that are not contained within active design option: use inverted filter to match elements
ElementDesignOptionFilter notActiveOptFilter = new ElementDesignOptionFilter(activeOptId, true); // inverted filter
collector = new FilteredElementCollector(document);
ICollection<Element> notActiveOptWalls =
    collector.WherePasses(notActiveOptFilter).OfClass(typeof(Wall)).ToElements();
