Is there a way to get surfaces volumes from Dynamo?

This works for me:

vs_name = IN[0]

adoc = Application.DocumentManager.MdiActiveDocument
editor = adoc.Editor

with adoc.LockDocument():
    with adoc.Database as db:

        with db.TransactionManager.StartTransaction() as t:
            bt = t.GetObject(db.BlockTableId, OpenMode.ForWrite)
            btrID = bt.get_Item("*Model_Space")
            btr = t.GetObject(btrID, OpenMode.ForWrite)
            
            for oid in btr:
                obj = t.GetObject(oid, OpenMode.ForWrite)
                
                if isinstance(obj, TinVolumeSurface) and obj.Name == vs_name:
                    volumeSurface = obj
            
            props = volumeSurface.GetVolumeProperties()
            
            
            adjustedCutVolume = "Adjusted Cut Volume = " + str(props.AdjustedCutVolume)
            adjustedFillVolume = "Adjusted Fill Volume = " + str(props.AdjustedFillVolume)
            adjustedNetVolume = "Adjusted Net Volume = " + str(props.AdjustedNetVolume)
            
                    
            
            # 
            #

            # Commit before end transaction
            t.Commit()
            pass

# Assign your output to the OUT variable.
OUT = adjustedCutVolume, adjustedFillVolume, adjustedNetVolume

If you just want the integers and not strings then you can just remove the string addition and the “str()” command. If you add dir(props) to “OUT”, you can see all available properties.
