How do I turn off the "Map Base" Layer using API ?

By Partha Sarkar

I want to switch off the "Map Base" Layer using Map 3D API.

 

 

Here is the C# code snippet to switch off the "Map Base" Layer using Map 3D managed API :

 

using (Transaction trans = transManager.StartTransaction())

{

  ObjectId managerId = DisplayManager.Create(proj).MapManagerId(proj, true);

  MapManager manager = trans.GetObject(managerId, OpenMode.ForRead) as MapManager;

 

  if (manager != null)

  {

    currentmapId = manager.CurrentMapId;

    Map currentMap = trans.GetObject(currentmapId, OpenMode.ForWrite) as Map;

 

    IEnumerator iterator = currentMap.NewIterator(true, true);

    Type groupType = typeof(Autodesk.Gis.Map.DisplayManagement.Group);

 

    while (iterator.MoveNext())

    {

      ObjectId objId = (ObjectId)iterator.Current;

      Object obj = trans.GetObject(objId, OpenMode.ForWrite);             

 

      if (obj.GetType().ToString() == "Autodesk.Gis.Map.DisplayManagement.BaseElement")

      {

        Autodesk.Gis.Map.DisplayManagement.BaseElement baseElement = obj as Autodesk.Gis.Map.DisplayManagement.BaseElement;

        baseElement.SetVisible(0, false);                 

      }

    }

  }

  trans.Commit();

}
