I have a local coordinate system in my model, and I need to assign this system as the displacement coordinate system to a node. Please help with the Python API for this.

Thank you

    using the new Python Recorder in 2025.0 i got this:

    import hm
    import hm.entities as ent

    def run():
    from hm.mdi import apis
    model = apis.HmModelDebug()

    model.setreviewtransparentmode(mode=0)

    
collection = hm.Collection(model, hm.FilterByEnumeration(ent.Node, ids=[2, 4]))
    
system_entity = ent.System(model, 2)
    
# [TIP]: systemsetanalysis is deprecated.
    
model.systemsetanalysis(collection=collection, system_entity=system_entity)

    
model.setreviewtransparentmode(mode=1)

    
model.setreviewtransparentmode(mode=0)
