determine line belongs to block

Hello All

In  a drawing sketch there are many block & lines

If user selects a line then I want to capture event that whether that line belongs to sketchblock or it is just a line

Kindly guide me for the same

my code is as below

If swselmgr.GetSelectedObjectType(1) = 10 Then

       Set selLineInst = swselmgr.GetSelectedObject6(1, -1)

      'Debug.Print selLineInst.Layer

      If  selLineInst.Layer = "FORMAT" Then

      swModel.ClearSelection2 True

      Exit Function

       End If

   End If

The above code works fine when user selects a separate sketch line

but when user selects line that is part of block then what should be written

If swselmgr.GetSelectedObjectType(1) = 114 Then

   

   End If
