	GraphicsStyleId	The ElementId of the GeometryObject's GraphicsStyle
	IsElementGeometry	Indicates whether this geometry is obtained directly from an Element.
	IsReadOnly	Identifies if the object is read-only or modifiable. (Inherited from APIObject.)
	Visibility	The visibility.

// find the name of the GraphicsSytleCategory for every geometric primitive in a family instance
        Options options = app.Create.NewGeometryOptions();
        GeometryElement geomElem = element.get_Geometry(options);
        foreach (GeometryObject geomObj in geomElem)

//The ElementId of the GeometryObject's GraphicsStyle
                    GraphicsStyle gStyle = doc.GetElement(geomObject.GraphicsStyleId) as GraphicsStyle;
