Given a ply, what's the most efficient way of calculating its area using the Python API?
To tackle the above problem I'm doing: import hm import hm.entities as ent model = hm.Model() collection = hm.Collection(model, ent.Element, hm.Collection(model, ent.Set, f"Name={ply.name}")) area = model.hm_getmass(collection) This seems to work just fine but starts to run a lot slower when dealing with hundreds of plies…
