What you need to do then is use the following origin 0 0 0 delta 0 0 1 delta 0 0 0 delta 1 0 0
or something close to that. David
David, That's what I originally did, but then DX displays my grid which should lie in the x-z plane in the x-y plane, so my original coordinate system of (x,y,z) got mapped to (x,z,y). It displays fine and for most purposes would work, I could construct vectors from the components to match this permutation, but I'm afraid that I would then be unable to use say the curl operator since it is inherently handed. Any way, doing this allows the x-coordinate to vary fastest and puts things in the x-z plane correctly. # Define a set of regular points along the x-axis object "nx" class gridpositions 201 1 1 # Define a set of regular points along the z-axis object "nz" class gridpositions 1 1 401 # Construct a product array from this set of points object 1 class productarray term "nz" term "nx" Thanks, Tom
