Type: Double

Height of aperture box centered at the hit point for the hit test; reserved for future use.

allowOutside

Access: Input-only

Type: Boolean

• True: Pick point outside the table will select a cell.
• False: Pick point outside the table will not select a cell.

resultRowIndex

Access: Output-only

Type: Long

Remarks - SelectionSet

This method supports the filtering mechanism.

The following selection modes are available:

• Window: Selects all objects 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 space and model space and attempt to use the selection set.
• Last: Selects the most recently created visible objects.
• All: Selects all objects.

For more selection mode options, see the , , and methods. SelectByPolygonSelectAtPointSelectOnScreen

Remarks - Table

This function selects a cell in the table by specifying a point, viewing direction, and orientation. The row and column index of the selected cell are returned in resultRowIndex and resultColumnIndex.

Examples

VBA:

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
