Opening An Existing Model For Editing

To access the Grid Editor, select the ModOps | Grid | Edit command.
Click on the Open button in the Grid Editor toolbar or choose the File | Open menu option.
Locate the name of the grid model you wish to edit and click the Open button. RockWorks grid files have the file name extension ".RwGrd".
The program will read the contents of the requested file and display in the window a grid of squares. Each square represents a grid node, each with an X and Y location coordinate pair. Each node also has a Z-value of some kind. This might represent elevations of a formation, or concentrations of a geochemical element. The squares are color-coded by Z-value, with lowest values coded pink and highest values red in a cold-to-hot gradational color scheme. Null values (-1e27) will be left blank.
To view the X, Y, and Z values assigned to a particular node, simply use your mouse to position the pointer-shaped cursor on the node. The coordinates and Z-value will be displayed in the title bar at the top of the Editor window.
