Facing orientation for faced based element


I am trying to insert a cone ( Mass_Cone element) at some points in Revit model using Dynamo. The cones are pointing upwards and would like to know if there is way to change the facing orientation when inserting with dynamo.There is node “Familiy.FacingOrientation” but it seems it gives you the vector perpendicular to the plane the element is placed. On broader question I am looking for a way to insert faced based element in Revit using Dynamo.
