Hi, I guess I fired this off a little too quickly! I found the answer through looking at some of the examples in the userguide and believing that whoever sat down and worked out the data model for DX was a true mathematician. Sure enough, DX is general enough. The answer was to simply use a few 1-D gridpositions and then make a productarray out of them. If anyone cares for more details just let me know and I'll try to describe it in some clarity.

So my original grid which is (x,y,z) gets mapped to >(x,z,y).
