Get Material from SwDocumentMgr API

Hi All - I need to be able to pull the Weight and the Material from a .sldprt file. I am able to get the Mass by the following:

swClassFact = CreateObject("SwDocumentMgr.SwDMClassFactory")

swDocMgr = swClassFact.GetApplication(sLicenseKey)

swDoc = swDocMgr.GetDocument(sDocFileName, nDocType, False, nRetVal)

swCfgMgr = swDoc.ConfigurationManager

Dim bRet As SwDmMassPropError

Dim obj As Object

obj = swCfg.GetMassProperties(bRet)

but I cannot figure out how I can get the Material?

Can anyone help please?

TIA,

jj
