The Spline layer has a range of special options that are accessed by RMC on the spline title in the tree view (Figure 1Spline Layer: RMC Options (new)). These options are summarized in the 2123694081 Spline Layer: RMC Options (new).

RMC on the grid layer, then select Properties, and the Grid Properties will be displayed, as shown in Figure 2. The options here include:
- Layer Name: show the name of the layer, a new name can be entered here
- Layer Visible: unchecking this box will hide the grid layer ( the light bulb of the layer in the Control Panel is also turned off)
- Show Lines: unchecking this box will hide the gridlines but sill other show properties of the grid e.g. Orthogonal Deviation. This is demonstrated in Figure 3.
- Line Settings: allows the changing of setting style, color, and thickness of the gridlines.
...
A number of options for displaying the properties of the grid layer are shown in 2123694081 Spline Layer: RMC Options (new) and further described in 2123694081 Spline Layer: RMC Options (new).

| None | Show the grid only |
| Orthogonal Deviation | Show the orthogonal deviation of the grid by color ramp (see 2123694081Spline Layer: RMC Options (new)) |
| Cell Aspect Ratio | Show the cell aspect ratio of the grid by color ramp (see 2123694081Spline Layer: RMC Options (new)) |
| Cell Area | Show the area of the grid cells by color ramp (see 2123694081Spline Layer: RMC Options (new)) |
| Cell DX | Show the dimension DX of the grid cells by color ramp (see 2123694081Spline Layer: RMC Options (new)) |

| Option | Description |
|---|---|
| None | Only the grid is displayed |
| Cell L Index | Show the L index number of the grid cells, each cell has only an L index. (2123694081Spline Layer: RMC Options (new)) |
| 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. (2123694081 (Spline Layer: RMC Options (new)). This option sometimes is helpful when we create a new grid that we want to merge with the previous grid. In this case, we need to know the number of cells along a segment of the previous grid. |
| Nodal 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. (2123694081Spline Layer: RMC Options (new)) |
| Bottom Elevation | To be implemented later. |
...
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 2123694081 Spline Layer: RMC Options (new).
Grid Indexing includes a number of options that are summarized in 2123694081 Spline Layer: RMC Options (new):
Table 4. Grid IndexingAnchor Table 4 Table 4
| 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. |
...
The Export option allows the saving of the grid to a file. A range of different file formats are supported as shown in Figure 14 and further summarized in 2123694081Spline Layer: RMC Options (new). The function of these options is similar to the Export button described in Main toolbar buttons.
...
Once selecting the Export Grid option, the Export to Grid form will be displayed, as shown in 2123694081 Spline Layer: RMC Options (new). Define the file type from the drop-down list then enter a file name. Define the folder location to locate the file then click the Save button.
