Creates an empty face in the geometry being built. Other BRepBuilder methods are used to add loops to the face.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 21.0.0.0 (21.1.1.109)
Since:  2016

Syntax

C#
public BRepBuilderGeometryId AddFace(
	BRepBuilderSurfaceGeometry surfaceGeom,
	bool bFaceIsReversed
)
Visual Basic
Public Function AddFace ( _
	surfaceGeom As BRepBuilderSurfaceGeometry, _
	bFaceIsReversed As Boolean _
) As BRepBuilderGeometryId
Visual C++
public:
BRepBuilderGeometryId^ AddFace(
	BRepBuilderSurfaceGeometry^ surfaceGeom, 
	bool bFaceIsReversed
)

Parameters

surfaceGeom
Type: Autodesk.Revit.DB..::..BRepBuilderSurfaceGeometry
The face's support surface.
bFaceIsReversed
Type: System..::..Boolean
True if the face's orientation is opposite to that of the surface, false if the orientations agree. The faces of each shell must be consistently oriented. For a solid (BRepType == Solid), the oriented face normals must point out of the solid; for a void (BRepType == Void), the face normals must point into the void. See the description of the bCoEdgeIsReversed input for AddCoEdge() for a discussion of the loop and co-edge orientation conventions to use with the BRepBuilder.

Return Value

An id that can be used to identify the face while the BRepBuilder is actively building geometry (e.g., to add a loop to a face).

Exceptions

ExceptionCondition
Autodesk.Revit.Exceptions..::..ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions..::..InvalidOperationException This BRepBuilder object isn't accepting new data, either because it has already been used to build geometry, or because of an error. Consult the State property of the BRepBuilder object for more details.
