| One usefull technique is to bend the polystyrene card around a former and pour hot water over it. Trial and error will determine the radius of the former and the material will flex back to a small degree after it is removed. For more complex curves use thinner card of say 0.3, 0.4 or 0.5 mm and for the straight edges to give the structure a bit more rigidity you could use 1.0mm card.
Scoring and bending is also a very usefull technique and helps to keep things in line and square.
