Does anyone know the best way of curving or otherwise shaping polycarbonate?

In the past, i've used a pan of boiling water and placed HDPE into it, then shaping immediately after, and a high powered heat gun works as an alternate. Do these methods work for polycarb, and if they do - does the polycarb loose its famous strength after being subjected to the shaping?

If neither of the above work, i'd love to hear an alternative shaping method, if any exist.
