Note

Because an A3DTopoBody entity is an abstract class, you cannot create directly such entity. Instead, use the appropriate derived function (such as A3DTopoSingleWireBodyCreate or A3DTopoBrepDataCreate) to create a specific topology entity. Then use this function to specify values in the entity base class. For example, this function specifies a value for the A3DTopoBodyData::m_pContext.
