Testing if a material exists in a library

[meGVGMF]

Hi,

I'm trying to see if the material of the active model state exists in a given library.

I thought I'd be able to use the `MaterialAsset.Name` property, which for library ones is a UUID, but seems to be a simple string for, at least, `ThisDoc.Document.ActiveMaterial`.

Is it possible to access this UUID somewhere within the `Document` object?

Thanks

No clue what UUID is. But if I want to find the material in the library i use something like this:

Dim oApp As Inventor.Application = ThisApplication
Dim oDoc As PartDocument = ThisDoc.Document
Dim assetLib As AssetLibrary = oApp.AssetLibraries.Item("Inventor Material Library")

For Each oAsset As Inventor.MaterialAsset In assetLib.MaterialAssets
If oAsset.DisplayName = oDoc.ActiveMaterial.DisplayName Then
	MsgBox("Yay! Found it")
End If
Next

The only way I know to do this is to loop through the library assets looking for the string value. Can you supply the code your working with? This vba sample for appearance would do just that when asset changed for material.

I'm actually trying to get around using `.DisplayName`, because if the name changes the material would go unrecognized.

The universally unique identifier/UUID value of the `.Name` for assets in the library is a 128-bit string in the format 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' that is, for all intents and purposes, unique.

Using this instead would cause fewer false negatives in the comparison and allow for more flexibility in the logic.

Thanks, but I'm trying to get around using the `.DisplayName` for identification.
