The data prompter is more limited than the DX data model in terms of what "exotic" options it supports. But you don't really need the data prompter to understand your positions; you just need to import the data, which is presumably all that's in the file? So use the data prompter and just give it some dummy positions; for example just one dimensional from 0 to n-1. Then use Construct to *make* the positions you really need (you are allowed to give vectors for the deltas in Construct). Then use Replace to stuff the positions out of Construct *into* the field you import with the dummy positions.

I'm trying to visualize a 3D grid (of charge density) which is not rectangular, but does have regularly spaced data points. (It's actually a hexagonal grid.) In particular, I'm having problems getting the data prompter to accept my deltas (which need to be vectors rather than scalars) in its input fields. For example, I'd like to set-up a grid having the following characteristics: origin = 0,0,0 delta_1 = 1, -1, 0 delta_2 = 0, 1, 0 delta_3 = 0, 0, 1 Is such a thing possible? Thanks! don | Donald J.
