Here you can find code snippits that show how the API call engiGetEntityCount can be used.

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

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