You can in Python, but not VS.    Completely untested, but something like this should get you the group that represents the LS definition, and you can start to iterate over its geometry   hLS = vs.GetObject('<LINE STYLE NAME>') if hLS: hAuxItem = hLS.aux kTypeGroup = 11 while ( vs.GetTypeN(hAuxItem) != kTypeGroup and vs.GetTypeN(hAuxItem) != 0): hAuxItem = vs.NextObj(hAuxItem) if ( vs.GetTypeN(hAuxItem) == kTypeGroup): hLSGeometry = vs.FIn
