[Paraview] [Non-DoD Source] Re: [EXTERNAL] Re: Rendering issue with cross-sections in 3D

Hi all,

Utkarsh's suggestion to transform the dataset closer to the origin using a
translation seems to have worked for me. I was working in UTM coordinates,
so I was working about 6,000 km away from the origin of the coordinate
system. Thanks for your help, Utkarsh!

All the best,
Craig
