Hello Irvin,

Hope this helps:
'Create Layer Group Filter Containing Layers just created
Private Sub CreateLayerFilter(ByRef db As Database, ByVal filename
As String)
Dim lft As LayerFilterTree = db.LayerFilters
Dim lfc As LayerFilterCollection = lft.Root.NestedFilters
Dim lgt As New LayerGroup
Dim lf As New LayerFilter
Dim t As Transaction = db.TransactionManager.StartTransaction()
Dim lt As LayerTable = t.GetObject(db.LayerTableId, OpenMode.ForWrite)

lgt = New LayerGroup
lgt.Name = filename.ToUpper

'get the layerid for each existing layer and add to layer group
For Each ltrID As ObjectId In lt
lgt.LayerIds.Add(ltrID)
Next
lfc.Add(lgt)
db.LayerFilters = lft
t.Commit()
End Sub

Excuse me.

Is it possible get LayerCollection for kind "LayerFilter"?

With the method "LayerIds" we can get LayerCollection for "LayerGroup" but this method doesn´t exist for "LayerFilter".

Thank you.
