Lester, Sorry for the late reply.
I was able to load your attached dataset without any issues with the following property values for the TableToStructuredGrid filter: Whole Extent (0, 140), (0, 151), (0, 2) X Column: X Y Column: Y Z Column: Z Utkarsh On Fri, Jul 24, 2009 at 6:54 AM, Lester Anderson <[email protected]> wrote: > Hi Utkarsh > > Thanks for the info, I can now see how it works from your sample file.
