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

Option	Description
Properties	Set properties of the selected layer (described in detail below)	Show Properties
Set properties of Create Grid	Generate grid from the selected spline layer (described in detail below)
Show Labels	Show labels by L or I, J indices of the grid (described in detail below)
Zoom to Layer	Zoom the view to the selected layer	Grid Indexing	Show different options for indices of the grid
Export Control Points To	Export the selected spline layer to an external file with a different optional format. It describes in detail below
Remove	Delete the selected layer
Create New Spline Layer	Create a new spline layer in the layer control panel
Create New Overlay Layer	Create a new overlay layer in the layer control panel
Turn All Layers Off	Hide all existing layers in the layer control panel
Turn All Layers On	Display all existing layers in the layer control panel

Spline Properties

RMC on the grid layer, then select Properties, and the Grid Properties will be displayed, as shown in Figure 2. The options here include:

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

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 an L index. (Spline 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. (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. (Spline Layer: RMC Options (new))
Bottom Elevation	To be implemented later.

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.
