Parameters

document Document: The document in which the new wall is created.
curve Curve: A curve representing the base line of the wall.
wallTypeId ElementId: Id of the wall type to be used by the new wall instead of the default type.
levelId ElementId: Id of the level on which the wall is to be placed.
height Double: The height of the wall other than the default height.
offset Double: Modifies the wall's Base Offset parameter to determine its vertical placement.
flip Boolean: Change which side of the wall is considered to be the inside and outside of the wall.
structural Boolean: If set, specifies that the wall is structural in nature.

Return Value

Wall
If successful a new wall object within the project.

Exceptions

Exception	Condition
ArgumentException	The curve argument is not valid for wall creation.
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	The given value for height must be greater than 0 and no more than 30000 feet. -or- The given value for offset must be no more than 30000 feet in absolute value.
ModificationForbiddenException	The document is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document is being loaded, or is in the midst of another sensitive process.
ModificationOutsideTransactionException	The document has no open transaction.

Example

C++

Copy

public Wall CreateWallUsingCurve2(Autodesk.Revit.DB.Document document, Level level, WallType wallType)
{
    // Build a location line for the wall creation
    XYZ start = new XYZ(0, 0, 0);
    XYZ end = new XYZ(10, 10, 0);
    Line geomLine = Line.CreateBound(start, end);

    // Determine the other parameters
    double height = 15;
    double offset = 3;

    // Create a wall using the location line and wall type
    return Wall.Create(document, geomLine, wallType.Id, level.Id, height, offset, true, true);
}

Public Function CreateWallUsingCurve2(document As Autodesk.Revit.DB.Document, level As Level, wallType As WallType) As Wall
    ' Build a location line for the wall creation
    Dim start As New XYZ(0, 0, 0)
    Dim [end] As New XYZ(10, 10, 0)
    Dim geomLine As Line = Line.CreateBound(start, [end])

    ' Determine the other parameters
    Dim height As Double = 15
    Dim offset As Double = 3

    ' Create a wall using the location line and wall type
    Return Wall.Create(document, geomLine, wallType.Id, level.Id, height, offset, _
        True, True)
End Function
