The 2DV View button and the icon 
of the main toolbar provide provides access to the profile/cross-section post-processing utility of EFDC_Explorer EE, as shown in Figure 1 223248391. This option was called ViewSlice in previous versions of EE. If no 2DV View has been created yet, the only option available to the user is New 2DV View button.

Figure 2. Data Extraction for 2DV View form.
The Profile Definition frame needs to be set first before a profile can be extracted from EFDC. There are three options shown in Figure 2. The user may either select a value of I to extract the active J cells along that I, or select a value of J to extract the active I cells along that J. The third option is to use a "Drape Line", which is a polyline in the same coordinate system as the LX, LY data. The I & J's from along the line will be assembled and the profile will be output along that slice. If an I or J extraction is used, the user can scroll up and down the selected coordinate.
The user select should then select which parameters are to be displayed in Define Parameter to Plot frame. First choose the Primary Group, then the necessary Parameter from that group and select the left arrow button 
. The user may select more than one parameter to plot. The parameters selected are displayed in Parameters to Plot frame, where the user can also remove the paramater by using the right arrow button 
save current 2DV layout, load external 2DV layout or move the layers up and down. This will change the order in which layers are drawn by EE. The Update button will replace the currently highlighted parameters in Parameters to Plot frame with the currently selected parameters in Define Parameter to Plot frame. The Properties button will open the 2DV View Properties form where the user can configure the color ramp, contour, precision, range and other settings (Figure 3). Click OK to plot 2DV View.

An example of the plot is shown in Figure 4. The contents of the current cell can be displayed, as in 2DH View, by LMC on the cell. Many of the operations of this feature are similar to 2DH View.

Similar to 2DH View, RMC on various elements of the plot (axes, title, legend) allows the user to edit and re-configure them.
Toolbar Menu
With the 2DV View window selected as the current window, clicking on 2DV View on the main toolbar will show additional menu items (Figure 5). These items provide the user with helpful functions like markers, comments, control view, import and export data series as described below.
...
Figure 5. 2DV View toolbar menu.
Format Data Items: Open the form Data Extraction for 2DV View.
Chart Settings: Allows the user to change the font, box line, content of the main/sub-title. Allow user to change the format, line length, column number, background color, border style of the legend. Allow the user to change the font, content, position, scaling of the axes.
Marker Settings: Allows the user to set a marker line at any value of the axes. Choose the X or Y axis in Orientation frame and then choose the value of the marker in Value box. Line style, color or shape of symbol can also be customized.
Comments: Allows the user to add comments into the plot. The font, content, color and background color of the comment can also be adjusted here. Check on the Visible check box to enable the comments.
Change Fonts: Allows the user to increase/decrease the font size for all the axes/ legends at once.
Zoom Full Extent: Zoom to the full extent of the data range.
Change View: Tools that assist the user in controlling of the view-port/camera.
Export/Import Data Series: Export the current data of 2DV View so that it can be imported as drape file later. The user has the option to choose the location of the file with Browse, by default the animation will be saved in #analysis folder of the active model.
Save/Load Layout: Save the current layout settings of 2DV View (axes, legend,... settings) as an .VSL file so they can be loaded later. The user has the option to choose the location of the file with Browse, by default the file will be saved in #analysis folder of the active model.
As with the 2DH View, the user can export images and animations from the plot with Generate Image and Generate Animation.
Generate Image: the user should the name for the image and select the folder the user wants to save out the image by clicking Browse button then click OK button to finish, by default the image will be saved in #analysis folder of the active model.
Generate Animations: display the Generate Bitmap/Animation form, by default the animation will be saved in #animations folder of the active model. Alternatively, the user can set name for the animation and folder to save out the image by clicking Browse button. Setting options for the animation file can be applied in this form such as start/stop animation timing, and number of time steps to skip. Finally click OK button to start exporting the file (see Figure 6).
The results of any of the time dependent results can be output as an animation to an AVI file. If the animation is to be saved to an AVI file, the user is asked for the number of frames per second to be output to the file. This will be application specific, but a number of 4 frames per second generally provides a fairly smooth, but not too fast animation. The user should be aware that these files can get quite large quickly. The frame size of the animation will match the frame of the 2DH View. Press the "Escape" key to stop an animation.
