Issue with listing material assets from custom library

Re: Inventor forum post - Solved: Odd Material-001, Material-002, Material-003, etc???? - Autodesk Community - Inventor

Getting material asset display names is still an issue when the ActiveMaterialLibrary is a custom user library.

Opening a part file with a custom material library and running the following VBA code results in the printout in the image following the code.

Public Sub LibTest()

    Dim lib As AssetLibrary
    Set lib = ThisApplication.ActiveMaterialLibrary
    
    For i = 1 To lib.MaterialAssets.Count
        Debug.Print i & "  " & lib.MaterialAssets(i).DisplayName
    Next i
    
End Sub

Partial debug window

Many of the materials have a "Material-xxx", "MaterialInv-xxx", or "MaterialSim-xxx" display name.

If the user then drops down the Material List in Inventor

And then runs the same macro, the display names have updated to the expected values.

So, what is the process to force this update before extracting the display names? They are obviously materials that are being referenced from the Autodesk and Inventor material libraries.

Hi @nmunro.  Just a thought, for a temporary workaround until this gets resolved properly...have you tried setting the ThisApplication.ActiveMaterialLibrary to a different 'AssetLibrary', then back to the one you want, then do a document update, before trying to list out the material display names.  Seems like something logical to try, that might help correct what seems to be a memory related issue.

Thanks for the suggestions. I have tried a number of approaches without success, including your suggested workflow. It appears that Inventor does not resolve the material library when it is first loaded, waiting until it is first accessed. Now looking at a manual reminder for users to force the update or a complex asynchronous timer approach to run a command that will force the update.
