When a 3D cell-centered grid is in memory, two viewing modes are available: '''General Mode''' and '''Orthogonal Mode'''. The general mode is the default mode and it is the mode used when a cell-centered 3D grid is not in memory. In general mode you can view the grid from top, front, or side view or from any oblique view. With the orthogonal view, the viewing | When a 3D cell-centered grid is in memory, two viewing modes are available: '''General Mode''' and '''Orthogonal Mode'''. The general mode is the default mode and it is the mode used when a cell-centered 3D grid is not in memory. In general mode you can view the grid from top, front, or side view or from any oblique view. With the orthogonal view, the viewing directions are restricted to three views: looking down the i, j, or k axes. As you look down an axis, you view one row, column, or layer at a time. Oblique views and shading are not available in the orthogonal mode. The default viewing mode for cell-centered 3D grids is the orthogonal mode. Thus, whenever a new cell-centered grid is created or read from a file, GMS automatically goes into the orthogonal viewing mode | ||

A command is provided in the ''View'' menu for switching between the orthogonal and general viewing modes. If the current mode is orthogonal, the menu command | A command is provided in the ''View'' menu for switching between the orthogonal and general viewing modes. If the current mode is orthogonal, the menu command titled '''Ortho Mode''' is selected. If the current mode is general, the command titled '''General Mode''' is selected. There is also a toolbar Macro that can be used to switch the mode . | ||

When in | When in orthogonal mode, the '''Mini-Grid Plot''' is activated in the [[GMS:Toolbars|Tool Palette]]. The plot shows which row, column, or layer is currently being displayed. The edit field and arrows just beneath the plot can be used to change the current row, column, or layer. To change the view, select one of the '''View Along I Axis''', '''View Along J Axis''', or '''View Along K Axis''' macros at the bottom of the Tool Palette. | ||

If this mode is selected, | With [[GMS:MODFLOW|MODFLOW]] models, a special viewing option called the '''True Layer''' mode is available. <!--If this mode is selected,--> MODFLOW includes a set of top and bottom elevation arrays for each layer. These arrays can be edited using the [[GMS:Global Options/Basic Package#Top_Elevation|''Top Elevation'']] and [[GMS:Global Options/Basic Package#Bottom_Elevation|''Bottom Elevation'']] arrays accessed through the ''MODFLOW Global/Basic Package'' dialog. These arrays can be used to display the vertical variations in the stratigraphy when in one of the side views in orthogonal viewing mode or when in oblique view in general mode. The ''True layer display'' option is found on the ''3D Grid'' tab of the ''Display Options'' dialog. That option controls the display of the vertical variations in stratigraphy based on data from the MODFLOW elevation arrays. | ||
