    hi,

    window means "all elements fully within the selection-rectangle"
    crossing means "all elements that are fully or partially within the rectangle"

    hi ..

    my intention is to know the logic behind the selection of entities. when we specify the 2 corners . how the entities are getting selected . what spatial query is running behind.

    Thanks

    i'm not sure if i understand you correctly

    if your question is how to select entities with autocad then read
    the autocad-dev-help on "SelectionSet" (or look in this newsgroup).

    if your question is, how autodesk programmed it, then sorry....
