Property model

Size: 32 bit / 4 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property entity

Size: 32 bit / 4 byte (value)
...

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

Int64 localGetEntityExtentBN(Int64 model, byte[] entityName)

    //  This function is an alternative to the API call sdaiGetEntityExtentBN()
    //  based on sdaiGetEntityExtent().
    //
    //  Use of sdaiGetEntityExtent() can lead to performance improvement compared to sdaiGetEntityExtentBN().
    //
    Int64 entity = ifcengine.sdaiGetEntity(model, entityName);

    return ifcengine.sdaiGetEntityExtent(model, entity);
