using RDF;      //  include at least engine.cs within your solution

Int64 localIsKindOf(Int64 instance, Int64 entity)
{

    //  This function is an alternative to the API call sdaiIsKindOf()
    //  based on sdaiGetInstanceType() and engiGetEntityParent().
    //
    //  Use of sdaiCreateAggr() can lead to performance improvement compared to sdaiCreateAggrBN().
    //
    Int64 instanceEntity = ifcengine.sdaiGetInstanceType(instance);

    while  (entity !=  0  &&  entity != instanceEntity)
    {
        entity = ifcengine.engiGetEntityParent(entity);
    }

    if (entity == instanceEntity)
    {
        return 1;

    return 0;
