ComputeVolumes Property

Area Volume Settings Compute Volumes Property

True to enable volume computation. False to disable it.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public bool ComputeVolumes { get; set; }

Property Value

Boolean
Remarks
When this setting is False, rooms and spaces will be treated as simple extrusions of their 2d boundaries. The volume parameter will report "not computed". When this setting is True, the geometry of rooms and spaces will be trimmed when it intersects elements such as ceilings, roofs, and floors.
Example 
public void GetRoomDimensions(Document doc, Room room)
{
    String roominfo = "Room dimensions:\n";
    // turn on volume calculations:
    using (Transaction t = new Transaction(doc, "Turn on volume calculation"))
    {
        t.Start();
        AreaVolumeSettings settings = AreaVolumeSettings.GetAreaVolumeSettings(doc);
        settings.ComputeVolumes = true;
        t.Commit();
    }

    roominfo += "Vol: " + room.Volume + "\n";
    roominfo += "Area: " + room.Area + "\n";
    roominfo += "Perimeter: " + room.Perimeter + "\n";
    roominfo += "Unbounded height: " + room.UnboundedHeight + "\n";
    TaskDialog.Show("Revit",roominfo);
}
