Autodesk.Revit.DB.Structure.StructuralWallUsageFilter

The Autodesk.Revit.DB.Structure.StructuralWallUsageFilter class is a filter used to select walls based on their structural usage. This filter is available in Revit's API through the ElementParameterFilter class.

Properties

This filter has the following properties:

• StructuralUsage - an enumeration that lists the different types of structural usage that a wall can have. This property can be used to filter walls based on their usage, such as structural or non-structural.

Constructors

The Autodesk.Revit.DB.Structure.StructuralWallUsageFilter class has the following constructor:

• StructuralWallUsageFilter(StructuralWallUsage usage) - creates a filter based on the specified structural wall usage.

Examples

The following example code snippet shows how to use the Autodesk.Revit.DB.Structure.StructuralWallUsageFilter class to select all walls that have a structural usage:

// Create a filter for walls with a structural usage
ElementParameterFilter filter = new ElementParameterFilter(
    new StructuralWallUsageFilter(StructuralWallUsage.Structural)
);

// Get all walls that match the filter
IList<Element> matchingWalls = new FilteredElementCollector(doc)
    .OfCategory(BuiltInCategory.OST_Walls)
    .WherePasses(filter)
    .ToList();

Remarks

Using filters to select elements in Revit can greatly simplify the process of manipulating model elements through the API. The Autodesk.Revit.DB.Structure.StructuralWallUsageFilter class is just one example of the many filters available in Revit's API.
