I may be confused by the terminology, but it sounds to me like you want to be able to control lighting from three locations, one being a dimmer switch.
If I am correct, this can be done with a 3-way switch, a 3-way dimmer, and a 4-way switch. The issue I imagine you may have is that wires called travelers must interconnect the 3 devices. If your wiring is in conduit and all three locations are piped together, this is fairly simple. If not, post further information.
