```csharp
using SCH;

ISch_Document currentSheet = SCH.GlobalVars.SchServer?.GetCurrentSchDocument();
if (currentSheet == null)
    return;

var rect = new CoordRect();
if (!currentSheet.ChooseRectangleInteractively(ref rect, "Please select the first corner", "Please select the final corner"))
    return;

ISch_Iterator spatialIterator = currentSheet.SchIterator_Create();
if (spatialIterator == null)
    return;
try
{
    spatialIterator.AddFilter_ObjectSet(new SCH.TObjectSet { TObjectId.eJunction, TObjectId.eSchComponent });
    spatialIterator.AddFilter_Area(rect.Left, rect.Bottom, rect.Right, rect.Top);
    for (var graphicalObject = spatialIterator.FirstSchObject() as ISch_GraphicalObject; graphicalObject != null;
         graphicalObject = spatialIterator.NextSchObject() as ISch_GraphicalObject)
    {
        // Do what you want with the design object.
    }
}
finally
{
    currentSheet.SchIterator_Destroy(ref spatialIterator);
}
```
