If you want to transfer the exact mass (calculated by CAD) in a Teamcenter attribute like PDM return mapping, you need to "register your own placeholders".[29]
[CadReturnMapping]
Key1=cstr(ScriptingRoot.GetAttributeUtils().LookupAttribute(activeDoc,"NB").GetValue())
Key2=cstr(ScriptingRoot.GetAttributeUtils().LookupAttribute(activeDoc,"NN").GetValue())
Key3=cstr(ScriptingRoot.GetAttributeUtils().LookupAttribute(activeDoc,"Mass").GetValue())
[TeamcenterAttributes_Item{ModelObject}]
object_desc=%Key3%
