Use Filter Lists to Define Selection Set Rules

Filter lists are composed of pairs of arguments. The first argument identifies the type of filter (for example, an object), and the second argument specifies the value you are filtering on (for example, circles). The filter type is a DXF group code that specifies which filter to use. A few of the most common filter types are listed here.

For a complete list of DXF group codes, see Group Code Value Types in the DXF Reference.

The filter arguments are declared as arrays. The filter type is declared as an integer and the filter value as a variant. Each filter type must be paired with a filter value. For example:

FilterType(0) = 0            'Indicates filter refers to an object type

FilterData(0) = "Circle"     'Indicates the object type is "Circle"

Sub Ch4_FilterMtext()

   Dim sstext As AcadSelectionSet

   Dim FilterType(0) As Integer

   Dim FilterData(0) As Variant

   Set sstext = ThisDrawing.SelectionSets.Add("SS2")

   FilterType(0) = 0

   FilterData(0) = "Circle"

   sstext.SelectOnScreen FilterType, FilterData

End Sub
