A cone face of a 3d solid. 
   Namespace:   Autodesk.Revit.DB  
  Assembly:   RevitAPI  (in RevitAPI.dll) Version: 2015.0.0.0 (2015.0.0.0) 
Syntax
Remarks
 Cone faces are defined by cone surfaces bounded by edge loops. The surfaces provide natural UV parameterization to the faces. S(u, v) = Origin + v*[sin(HalfAngle)*(cos(u)*Radius[0] + sin(u)*Radius[1]) + cos(HalfAngle)*Axis] 
 Examples
private void GetConicalFaceInfo(Face face)
{
    ConicalFace conicalFace = face as ConicalFace;
    if (null != conicalFace)
    {
       XYZ axis = conicalFace.Axis;
       XYZ origin = conicalFace.Origin;
        double halfAngle = conicalFace.HalfAngle;
        XYZ radius = conicalFace.get_Radius(0);
    }
} Private Sub GetConicalFaceInfo(face As Face)
    Dim conicalFace As ConicalFace = TryCast(face, ConicalFace)
    If conicalFace IsNot Nothing Then
        Dim axis As XYZ = conicalFace.Axis
        Dim origin As XYZ = conicalFace.Origin
        Dim halfAngle As Double = conicalFace.HalfAngle
        Dim radius As XYZ = conicalFace.Radius(0)
    End If
