The Figure 1 shows RMC's options of a grid layer. These options are summarized in the Table 1.
Figure 1. Grid tab.
Table 1. RMC's options for grid layer.
| Option | Description |
|---|---|
| Properties | Set properties of the selected layer, it describes in detail below |
| Show Properties | Set properties of the selected layer, it describes in detail below |
| Show Labels | Show labels by L or I, J indices of the grid. it describes in detail below |
| Zoom to Layer | Zoom the view to the selected layer |
| Grid Indexing | Show different options for indices of the grid |
| Export To | Export the selected layer to an external file with a different optional format. It describes in detail below |
| Remove | Delete the selected layer |
| Create New Splines Layer | Create a new splines layer in the layer control panel |
| Create New Overlay Layer | Create a new overlay layer in the layer control panel |
| Turn All Layers Off | Show off all existing layers in the layer control panel |
| Turn All Layers On | Show on all existing layers in the layer control panel |

| Option | Description |
|---|---|
| None | Only the grid is displayed |
| Orthogonal Deviation | Show the orthogonal deviation of the grid. it is displayed by color ramp. (Figure 4) |
| Cell Aspect Ratio | Show the cell aspect ratio of the grid. it is displayed by color ramp. (Figure 5) |
| Cell Area | Show the area of the grid cells. it is displayed by color ramp. (Figure 6) |
| Cell DX | Show the dimension DX of the grid cells. it is displayed by color ramp. (Figure 7) |
| Cell DY | Show the dimension DY of the grid cells. it is displayed by color ramp. (Figure 8) |

Show Labels
Table 3. Show Labels for grid layer.
| Option | Description |
|---|---|
| None | Only the grid is displayed |
| Cell L Index | Show the L index number of the grid cells, each cell has only a L index. (Figure 9) |
| Cell I,J Indices | Show the I and J indices number of the grid cells, each cell has a pair of I and J indices. (Figure 10). This option sometimes is helpful when we create the next grid to merge with the previous grid as we want to know the number of cells along a segment of the previous grid. |
| Node I,J Indices | Show the I and J indices number of the grid nodes, each grid node has a pair of I and J indices. (Figure 11) |
Figure 9. Show Labels: Cell L Index.

Grid Indexing
When a grid is generated each cell or node has an I and J coordinate. Sometimes these are not in the direction that the user requires. The Grid Indexing tool allows the user to reverse the I and J coordinates either separately, or at the same time.
To display the I, J labels of the grid, select the grid layer in the Layer Control then RMC. Select Show Labels (e.g Cell IJ Indices) as shown in Figure 10.
Grid Indexing includes options that are summarized in Table 4:
Table 4. Grid Indexing
| Option | Description |
|---|---|
| Transpose I - J Indices | Reverses both the I and J indices of the selected grid at the same time. |
| Flip I Indices | Reverses only the I indices of the selected grid. |
| Flip J Indices | Reverses only the I indices of the selected grid. |
| Rotate Indices Clockwise | Orders the indices in a clockwise direction. |
| Rotate Indices Counter-Clockwise | It is the opposite of the Rotate Indices Clockwise. |
Export To
EE10 allows you to export the 2DH View of the current layer for post-processing.
To export the layer, the user needs to Right Mouse Click (RMC) on the layer and select Export to as shown in Figure 1. The Save Data File will be displayed, the user should specify the type of the file and click OK.
The grid cells can be exported to several file format as shown in Figure 7.
| Option | Description |
|---|---|
| Export To Grid+ | The file of the grid cell will has format *cvl |
| Export To RGF Grid | The file of the grid cell will has format *RGF |
| Export To EFDC Grid | The file of the grid cell will has format *inp, which can import directly to EEMS model |
| Export To Shapefile | The file of the grid cell will has format *shp |
| Export To KML | The file of the grid cell will has format *kml |
| Export To Outline | The file of the grid cell will has format *p2d |
