- Add New Grid Connection Layer: Add N-S or E-W grid connectors for different grid domains. Select Grid Connections layer in Layer Control then RMC on a cell from one grid which is to be connected to another grid, and select Add N-S Connection (or Add E-W Connection), then LMC to set the second connection point (see View Layer Control#Figure 9).

- Add New Graticule Layer: this can be used to show the location in geographic coordinates (degrees latitude and longitude). RMC on the layer then select Properties, and the Graticule Settings form will be display. The user should customize the locations and interval of the lines as shown in View Layer Control#Figure 10 and View Layer Control#Figure 11. The graticule lines are displayed as shown in View Layer Control#Figure 12.

- Add New XYZ Scatter Layer: when this option is selected an XYZ layer is added to the Layer Control. RMC on the 2DH View window then select Create New Data Point which displays the Data Point form, in which X and Y are coordinates in meters of each point, Z is the third field which could be elevation or concentration etc. The initial value of Z is zero and the user can edit this value by entering a new value. If the user wants to update new coordinates for the point then enter new values for X and Y (see View Layer Control#Figure 13). When RMC on the XYZ layer in Layer Control like Properties (set properties for data point), option include Export (save the XYZ file out), Remove (delete the layer) as seen in View Layer Control#Figure 14.

- Add New Label Layer: this allows to add a label layer, after this option is selected a label layer is added to the Layer Control. The user can RMC on 2DH View window then select Create New Label, a form of Label Properties appears, in which X and Y are coordinates in meters, Z is a third field containing information of the point such as elevation as shown in View Layer Control#Figure 15. The initial value of Z is 9999999.88 to make sure that the label is not covered by other layers. In this form, the user can change properties for labels such as name, symbol style, color, font etc. There are further options when RMC on the label layer in Layer Control including Properties (set properties for labels), Import (import a label file), Export (save the label file out), Remove (delete the layer from Layer Control). (see View Layer Control#Figure 16).

- Add New Overlay Layer: when this option is selected, a layer named Vector Layer is added to Layer Control. Note that the pencil symbol should be enabled. The user can then go to Poly Tools
on the toolbar, select Draw Polyline and LMC on 2DH View window to start drawing a polyline. RMC to end drawing. RMC on the Vector Layer provides options such as Properties (set the properties for line and points of the polyline), Zoom to Layer, Save As and Remove. When the user selects Save As the Save As form appears, the user need enter a file name and file extension ( eg *.P2D, LDB, XYZ etc) then click Save button. As default the file is saved in #analysis folder as shown in View Layer Control#Figure 17, View Layer Control#Figure 18, and View Layer Control#Figure 19.

When there are a number of layers in the Layer Control, the user might want to arrange order of the layers by selecting the layer first then using Up/Down arrows (
).
There are four symbols accompanied with each layer: light bulb, arrow pointer, pen and label tag. Their meanings are described in View Layer Control#Figure 20.
RMC on each layer in Layer Control, provides a number of options including Properties, Zoom to Layer, Edit, Export, Remove as shown in View Layer Control#Figure 21. These options can vary depending the type of layer selected. The Properties layer provides important options for configuring the layer viewing.
