AreaVolumeSettingsComputeVolumes 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; }

Public Property ComputeVolumes As Boolean
	Get
	Set

public:
property bool ComputeVolumes {
	bool get ();
	void set (bool value);
}

member ComputeVolumes : bool with 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

C++

Copy

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);
}

Public Sub GetRoomDimensions(doc As Document, room As Room)
    Dim roominfo As [String] = "Room dimensions:" & vbLf
    ' turn on volume calculations:
    Using t As New Transaction(doc, "Turn on volume calculation")
        t.Start()
        Dim settings As AreaVolumeSettings = AreaVolumeSettings.GetAreaVolumeSettings(doc)
        settings.ComputeVolumes = True
        t.Commit()
    End Using

    roominfo += "Vol: " & Convert.ToString(room.Volume) & vbLf
    roominfo += "Area: " & Convert.ToString(room.Area) & vbLf
    roominfo += "Perimeter: " & Convert.ToString(room.Perimeter) & vbLf
    roominfo += "Unbounded height: " & Convert.ToString(room.UnboundedHeight) & vbLf
    TaskDialog.Show("Revit", roominfo)
