Is there a way to get the handles of the geometry of complex line styles?
I need to get the thickness of these lines.
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
