Beware of this when editing the grid close to the edge.// | //NOTE: The Grid Editor is affective only within the current scene extent.

| - | When editing 2D grids the node elevation is changed. When editing 3D grids the node //value// is changed. 2D grids are allways floating point value grids whereas 3D grids may be either floating point or discrete value grids, e.g., lithology. The availability of the grid editor form controls change according to the grid format. For floating point grids the node elevation or value is changed numeically whereas discrete value grid values are changed by assigning a symbol from a symbol list. | + | When editing 2D grids the node //elevation// is changed.

| The tool is applied within an area defined by shape and size parameters. The shape for 2D grids may be Ellipsis or Rectangle, and for 3D grids it may be Ellipsoid, Cylinder, Box, or Profile Polygon. The effective area or volume defined by the geometry may be further limited by region, surface, and value boundaries as described below. | The tool is applied within an area defined by shape and size parameters.
