In many countries these switches are called 'hotel' switches. It is possible that you call them 3-way switches, but that name is rather confusing, as there are only 2 switched in/out contacts involved, not three. The problem was not in the name of the switch, but in the wiring.

As Rozey rephrased here question elsewhere :

... put a switch at the entrance of the room to control one half of the large 'family room' and a switch for the other half{double switch}there are 5 lights in total that plug into receptacles;via the shop lights;then at the other end of the room as to go into the other rooms we want a way to shut off the lights without crossing back to the other end of the room to do so.

My response : there are two circuits involved here.
Circuit one : entrance of room for one half of room. To be switched from both sides of the room.
Circuit two : other half of room (towards other rooms). Additional here is the capacity to interrupt circuit one from a second switch.

You will have to place TWO switches next to each other at location two.
Switch 1 a normal on/off switch for circuit two.
Switch 2 a 'hotel' switch (together with a second 'hotel' switch) for cicuit one.

Wiring :

Circuit one :
Switching from both sides : life (black) direct to all lightfittings, and other side of all light fittings to 'hotel switch' one common. Two switching wires from 'hotel' switch one to 'hotel' switch two.
Common contact of second 'hotel' switch to neutral (white).

Circuit two : life (black) direct to switch contact, and second switch contact direct to all lightfittings in that circuit. Other side of all lightfittings to neutral (white).

As stated before : it is possible to combine the two switches next to each other in one, but that requires the services of an electrical professional, because some (expensive) electronics have to be installed.
