Change MembersToInclude of a PartsList

By Adam Nagy

In the UI you can change which member of an iPart or iAssembly is included by double clicking the parts list and then clicking the "Member Selection" button:

If you try to change the included member like this then you'll get an "Invalid procedure call or argument" error:

If something does not work then it's always good to try to do it through the UI and then check the results in the VBA Watches window:

If you did that then you'd find (as shown in the above image) that MembersToInclude stores an array of strings - so that's what you'd need to pass to it:

Sub ChangeMembersToInclude()
  ' The PartsList needs to be selected in the UI
  Dim oPL As PartsList
  Set oPL = ThisApplication.ActiveDocument.SelectSet(1)
  
  ' This works
  Dim members(0) As String
  members(0) = "iPart-02"
  oPL.MembersToInclude = members
End Sub
