The Null object is a specialized X3DObject object and represents a point in space with no dimensions. Nulls can be used to set constraints, organize objects into hierarchies, and so on.
using namespace XSI; Application app; Model root = app.GetActiveSceneRoot(); Null myNull; root.AddNull( L"MyNull", myNull ); app.LogMessage( myNull.GetFullName() );
