Remarks

This method supports the filtering mechanism.
The following selection modes are available:

• Window: Selects all entities completely inside a rectangular area whose corners are defined by Point1 and Point2.
• Crossing: Selects objects within and crossing a rectangular area whose corners are defined by Point1 and Point2.
• Previous: Selects the most recent selection set. This mode is ignored if you switch between paper and model space and attempt to use the selection set.
• Last: Selects the most recently created visible entity.
• All: Selects all entities.

For more selection mode options, see the SelectByPolygon, SelectAtPoint, and SelectOnScreen methods.
