If one of the classes this instance is instantiated from or one of its parents is a geometry class,
this class is returned. In all other cases the return value is 0.
Syntax
public const string enginedll = @"engine.dll";
[DllImport(enginedll, EntryPoint = "GetInstanceGeometryClassEx")]
public static extern Int64 GetInstanceGeometryClassEx(Int64 model, Int64 owlInstance);
Property model
Size: 64 bit / 8 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 owlInstance
Size: 64 bit / 8 byte (value)
The handle to the specific instance in the design tree. The instance handle is static within one open model but is most probably different when the same instance is opened in another model. The instance is always exactly of one unique class.
