void WriteEntities(Int64 model)
{
    Int64 i = 0, cnt = RDF.IFCEngine.engiGetEntityCount(model);
    while  (i < cnt)
    {
        Int64 ifcEntity = RDF.IFCEngine.engiGetEntityElement(model, i);
        string entityName = RDF.IFCEngine.engiGetEntityName(ifcEntity);
        Console.WriteLine("Entity  " + entityName);
