New part identifier

[Anonymous]

When Inventor creates a new .ipt part file I am guessing that it stamps the file with a unique identifier that will not change even if the file is emailed or edited by another user on another computer. Does anybody know how I can access this file identity type information? I have found some information in iproperties but its not in enough detail.

You doing some design forensics?

With a bit of vba programming. Get the Document object representing file, the InternalName property is a GUID that does not change.

Exactly. Emboczko, if you're unfamiliar with macros, the following should show a dialog displaying the active document's internal name:

Public Sub ShowInternalName()
  Dim oDocument As Inventor.Document
  'Make sure a document is open
  If ThisApplication.Documents.Count > 0 Then
    Set oDocument = ThisApplication.ActiveDocument
    MsgBox ("Internal Name: " & oDocument.InternalName)
  End If
End Sub

 You will need to copy/paste this code into a VBA document or application project. This document will help you get started if you have trouble running the macro.

The internal name property is set on document creation. This means that if you save a copy of an existing document (part, assembly, presentation, or drawing), it will have the same internal name as the source. Only when you create a new document from a template will you get a new unique internal name.
