Sub Example_Select()
    ' This example adds members to a selection set, first by crossing and
    ' then by filtering for circles.
   
    ' Create the selection set
    Dim ssetObj As AcadSelectionSet
    Set ssetObj = ThisDrawing.SelectionSets.Add("SSET")
   
   
    ' Add all object to the selection set that lie within a crossing of (28,17,0) and
    ' (-3.3, -3.6,0)
    Dim mode As Integer
    Dim corner1(0 To 2) As Double
    Dim corner2(0 To 2) As Double
   
    mode = acSelectionSetCrossing
    corner1(0) = 28: corner1(1) = 17: corner1(2) = 0
    corner2(0) = -3.3: corner2(1) = -3.6: corner2(2) = 0
    ssetObj.Select mode, corner1, corner2
   
    ' Add all the Circles to the selection set that lie within the crossing of (28,17,0) and
    ' (-3.3, -3.6,0) by filtering from the current drawing
    Dim gpCode(0) As Integer
    Dim dataValue(0) As Variant
    gpCode(0) = 0
    dataValue(0) = "Circle"
   
    Dim groupCode As Variant, dataCode As Variant
    groupCode = gpCode
    dataCode = dataValue
   
    ssetObj.Select mode, corner1, corner2, groupCode, dataCode
   
End Sub
