Grid Info
The Grid Editor | Options | Grid Info command or the 
button in the Grid Editor displays the file name, grid size in rows x columns, and grid X, Y, and Z minimums and maximums. If the grid file contains more than 40 million nodes, you are asked if you wish to create a detailed report or a quick report. Click Yes in the message to create a detailed grid report, or click No to create a shorter quick grid report. This is the same basic information as displayed in the plot window with the Grids | Info | Grid Info command.
The Open Grid dialog also displays the Grid Info of the selected grid. The Open Grid dialog displays the following Grid Info: Name, Format, Size, xMax, yMax, zMax, xMin, yMin, and zMin.
