Grid Tools
The Grid Tools button group contains buttons you can use to create an Easy Grid (to quickly set up and test simple modeling, upscaling, and reservoir simulation scenarios), extract a horizon to create a tri-mesh from a 3D grid layer, validate markers, and compute mismatches between markers and horizons.
