Getting the part/assembly thumbnail

[Jef_E]

Hi,

I'm making a program to clean my workspace ( inventor files ) but I would like to be able to see the thumbnail image of the file. How can I access it from outside Inventor?

I could use apprentice if required or can it be done without apprentice? For example how can I get the image shown by the windows explorer?

You can use Apprentice to view the thumbnail of Inventor documents, and I attached an Excel with VBA sample to preview the Inventor documents' thumbnail in a folder, when you run the UserForm1 in the VBA(change the folder path if necessary), and you can see below form, and the preview of an Inventor document, click on the image area it will continue to display next:

Hope this helps.

Here's a function you can use to read it:

Public Function iThumbnail(FilePath As String) As System.Drawing.Image
	If Not System.IO.File.Exists(FilePath) Then Return Nothing
	Dim oImg As System.Drawing.Image = Nothing
	Try
		Dim iApp As New Inventor.ApprenticeServerComponent
		Dim oDoc As Inventor.ApprenticeServerDocument = iApp.Open(FilePath)
		Dim SummaryInfo As Inventor.PropertySet = oDoc.PropertySets.Item("Inventor Summary Information")
		Dim ThumbProp As Inventor.Property = SummaryInfo.Item("Thumbnail")
		Dim Thumbnail As stdole.IPictureDisp = CType(ThumbProp.Value, stdole.IPictureDisp)
		If Not Thumbnail Is Nothing Then
			oImg = Compatibility.VB6.IPictureDispToImage(Thumbnail)
		End If
		oDoc.Close()
		iApp.Close()
	Catch Ex As Exception
		MsgBox(ex.Message)
	End Try
	Return oImg
End Function
