Hi all, at the end with try and error I succeed to export glTF files.
Dim oApp As Inventor.Application = ThisApplication
Dim oDoc As Document = oApp.ActiveDocument
Dim oOBJ As TranslatorAddIn
For Each oAppAddin As ApplicationAddIn In oApp.ApplicationAddIns
' MsgBox(oAppAddin.AddInType )
If oAppAddin.DisplayName = "Translator: glTF" Then
MsgBox(1)
oOBJ = oAppAddin
End If
Next
'The following lines create the needed input variables
Dim oTO As TransientObjects = oApp.TransientObjects
Dim oContext As TranslationContext = oTO.CreateTranslationContext
oContext.Type = IOMechanismEnum.kFileBrowseIOMechanism
Dim oOptions As NameValueMap = oTO.CreateNameValueMap
Dim oDataMedium As DataMedium = oTO.CreateDataMedium
Dim SavePath As String
Dim tDoc As Inventor.Document = ThisDoc.Document
SavePath = "\\192.168.2.101\erp\ERP_ROOT\OBJ_3Dmodels\"
oBaseName = tDoc.PropertySets.Item("Design Tracking Properties").Item("Part Number").Value
oRev = tDoc.PropertySets.Item("Inventor Summary Information").Item("Revision Number").Value
oRev = FormatRevisionNumber(oRev)
oDataMedium.FileName = System.IO.Path.ChangeExtension(SavePath & oBaseName & oRev, ".glb")
Try
oOBJ.SaveCopyAs(oDoc, oContext, oOptions, oDataMedium)
Catch
MsgBox(oBaseName)
End Try
