Introduction
What is GW3D?
GW3D is a program that works with Groundwater Vistas (GV) to view groundwater
models in three dimensions. GW3D is designed to view the model domain,
boundary conditions, aquifer properties, and model results. It is not designed to view
general hydrogelogical data. GW3D is based on the USGS program called Model
Viewer (Hsieh & Winston 2002), which has been extensively modified to interface
with GV and also the make it easier to use. Many enhancements have also been
added.
Both GW3D and Model Viewer are designed around the Visualization TookKit
(VTK) developed by Will Schroeder, Ken Martin, and Bill Lorensen. VTK is an
open source, freely available 3D graphics engine (Schroeder et al. 1997 and 2001).
The company that maintains VTK is called KitWare and can be found on the web at
http://public.kitware.com/VTK/.
Package Contents and Installation
What Comes with GW3D?
GW3D comes with the three-dimensional viewing software and a program to create
animations from bitmap files called bmp2avi. GW3D is sold as an add-on to
Groundwater Vistas and requires you to have a valid Groundwater Vistas Version 4+
license.
You also receive full, context -sensitive help with GW3D and an electronic manual
with tutorial that will help you get started. We also offer free technical support and
updates are distributed through our Internet ftp site or from our web site
(http://www.groundwatermodels.com).
Installing GW3D
GW3D is distributed on CD-ROM and uses an installation program that is similar to
other Windows products. Normally, setup will start as soon as you put the CD-ROM
Guide to Using GW3D
Introduction • 1
into your computer. If not, simply run setup.exe from the Program Manager File
menu or the Run option on the Windows Start menu and follow the directions as the
installation proceeds.
A dialog prompts for the hard disk drive letter and directory where the GW3D files
will be stored. The default is c:\gw3d. Enter a new path for GW3D if you would
like to place the files in a different directory. Click the OK button when you are
done (you may also press the Enter key to accept the drive and directory). Select
CANCEL at any time to terminate the installation process.
A dialog will now appear allowing you to name the Program Manager Group for the
GW3D icon. The default name is GW3D. To change the group name, you may
select from an existing group listed in the dialog or name a new one. Select OK to
accept your choice.
Uninstalling GW3D
You uninstall GW3D like any other Windows program. Double -click My Computer
and then double-click the Control Panel. Double-click the Add/Remove Programs
icon. Select GW3D from the list of programs and click the Add/Remove button on
the dialog. Just follow the prompts from the uninstall wizard from there.
Licensing
There are two licensing options with GW3D. The first option is to have a license for
Groundwater Vistas Version 4 Enterprise Edition, which comes with GW3D. You
then simply install GW3D on the same hard disk drive as the Groundwater Vistas
directory and GW3D will run whenever Groundwater Vistas is capable of running
(that is, you either have a security code for Groundwater Vistas or you have a
hardware lock for Groundwater Vistas Enterprise Edition).
The second licensing option is to purchase GW3D to work with an existing copy of
Groundwater Vistas (Standard or Advanced versions). In this case, you will then
need a separate security code for GW3D. To obtain a security code, run GW3D,
select Help/About GW3D and click the Register button. An example of the
registration window is shown below.
2 • Introduction
Guide to Using GW3D
Email the system code at the bottom of the dialog to
[email protected]. We will return a security code that goes in the
top of the dialog. Please do not call for the security code; a security code will only
be given out through email. If you purchased the software from any organization
other than ESI, please tell us where and when it was purchased.
Technical Support & Updates
Our technical support is always free! If you have a question or problem, feel free to
contact us either by email ([email protected]) or by phone. If it is
not an emergency, we prefer that you use email.

Getting Started with GW3D
Introduction
The first thing to consider when viewing a groundwater model in three dimensions is
that the model should be three-dimensional! That should be patently obvious;
however, even three dimensional models will not yield very pleasing results in 3D if
there are only a few layers. In a lot of cases, models tend to have just a very few
layers and in these cases, the three dimensional representation of such a model will
not be very spectacular. Therefore, if you know that one of your ultimate uses of the
model is to produce a cool animation or other 3D effect, you need to add more layers
than you might have originally planned. This is especially true for contaminant
transport analyses.
Launching GW3D from Groundwater Vistas
GW3D is designed to work with Groundwater Vistas and to view groundwater
models and model results in three dimensions. It is very easy to start using GW3D.
Simply open your model in Groundwater Vistas and select 3D\Options from the
main menu. This sets up the basic options before launching GW3D. The Options
dialog is shown below:
4 • Getting Started with GW3D
Guide to Using GW3D
The type of 3D view is either the default (which starts a new view of the model in
GW3D with basic options) or “Existing GW3D File”. The latter is used when you
already have a 3D view prepared in GW3D and just want to launch GW3D to view it
again. The name of the GW3D file is then placed in the field labeled “GW3D File
Name”. GW3D files use the extension “gw3”.
The Model Type is either MODFLOW or MT3D. Choose MODFLOW to view head
and drawdown information or MT3D to view concentrations.
The path to the GW3D program should be set appropriately if you installed GW3D
in the default directory. Otherwise, browse to find the file gw3d.exe.
GW3D will display the same base maps as your Groundwater Vistas model. Maps
can either be draped over the top of layer 1 or on a flat plane. In either case, the
distance between the map and the top of model layer 1 is also entered as the “gap”
value. The final option on the dialog is the vertical exaggeration. These last three
options on the bottom of the dialog can be changed after launching GW3D.
At the bottom of the dialog is a list of other data types that can be viewed in 3D. By
default, GW3D will display head, drawdown, and pathlines for MODFLOW or
concentrations for MT3D, and also positions of boundary conditions. Most other
matrix data types in Vistas can also be displayed, including hydraulic conductivity,
storage, etc.
After selecting the options above, choose 3D/Launch GW3D. Your screen should
then look like the one below.
Guide to Using GW3D
Getting Started with GW3D • 5
The view you get when you first start GW3D is from above the model domain
looking down on it, like the plan view in Vistas. Active cells are shaded a greenish
color. No-flow cells are not shown. Maps are displayed the same way they are in
Vis tas.
Guide to Using GW3D
Zoom, Rotate, and Pan
One of the first things you will want to do is change the view of the model by
zooming in or out, rotating the image, and panning. The first step in changing the
image is to click anywhere on the 3D image to make it active. Then click the 3D
button on the toolbar or select Edit/3D Manipulation/Mouse Mode. Now you are
free to manipulate the image using the following techniques:
•
Zoom in: press and hold the right mouse button and move the cursor upward.
•
Zoom out: press and hold the right mouse button and move the cursor downward.
•
Rotate: press and hold the left mouse button and move the cursor in the direction of rotation.
•
Rotate perpendicular to the screen: hold down the control key (CTRL), press and hold the left mouse
button, and drag in the direction of rotation.
•
Pan: hold down the shift key, press and hold the left mouse button, and drag the cursor in the direction
of panning.
The operation that takes the most practice is rotating the image. The manner in
which the image is rotated depends on not only the direction you drag the mouse but
on where you click to start the rotation.
Adding Features to the Image
GW3D can display the following types of information on the image:
•
Solid representation of data in each cell:
Guide to Using GW3D
•
Isosurface representation of data in each cell:
•
Velocity vectors:
Guide to Using GW3D
•
Particle-tracking pathlines from MODPATH:
•
Boundary Conditions: (the purple bar at left is a line of constant heads)
Guide to Using GW3D
These image features are toggled on and off from the View menu. The option called
Model Features primarily represents boundary conditions.
Display Options
There are numerous options for how each of these model features is displayed. The
options are controlled by clicking the
button on the toolbar or selecting
Options/Parameters. A tab dialog is then displayed, as shown below:
Most of the selections on this dialog are fairly easy to figure out. For detailed
information on each tab of this dialog, see the Image Options Chapter later in this
manual.
Saving the Image
When you have an image you like and want to be able to display it instantly in
GW3D, simply select File/Save As and give it a name. The file will have a *.gw3
extension. You can then open this file in GW3D and it will be displayed using the
same options as when you saved it. You may automatically launch GW3D from
Groundwater Vistas and open an existing *.gw3 file as described in the first part of
this chapter. You may als o double-click on the *.gw3 file in Windows Explorer to
open GW3D and display the image.
Animation
A common use of 3D visualization software is to create an animation of the model.
There are two ways of doing this in GW3D. The first is to create and play an
Guide to Using GW3D
animation on the screen within GW3D. This is accomplished using
Options/Animation. Next, set up the options such as number of seconds to display
each image. Finally click the Set button and the Run button to play the animation.
To make a permanent movie file that you can show at a later time, select File/Export
Animation. Fill in similar options as for the animation technique described above.
In addition, you specify a directory for the files and a root name for the image files.
A series of images will be saved in the directory with names in sequence. For
example, if the root name is test, then the firs image will be test001.bmp, etc.
Guide to Using GW3D
A simple application called bmp2avi.exe is provided with GW3D than can put these
files together into a movie. Check the option labeled “Create AVI Movie File” to
automatically run bmp2avi. The use of this program outside of GW3D is
documented in the file bmp2avi.htm. A typical command line would be:
bmp2avi –i test –o test –f 1
where “i” is the input name prefix, “o” is the output name (bmp2avi will attach a
*.avi extension), and the number after “f” is the number of frames per second.

Tutorial
Introduction
The GW3D exercise, described below, introduces you to most of the important
features of this software in a step-by-step example. You will be given very specific
instructions to show how to use GW3D to view a model that is provided in
Groundwater Vistas Version 4. In a graphical user interface such as Windows, it is
difficult to tell you exactly what to do during each step because many of the steps
involve using the mouse. This demonstration provides several snap-shots of the
GW3D screens to show you what your screen should look like, however, in case you
miss a step.
Running the Example Model
Before using GW3D, we need to run the example model in Groundwater Vistas.
Run Groundwater Vistas and open the file called
c:\gw3d\examples\gw3d_example.gwv. If you installed GW3D in another directory
then browse to find that directory. The model should look like the following:
Guide to Using GW3D
Tutorial • 13
This model is essentially the Groundwater Vistas tutorial example with a much finer
grid spacing and many more layers. As mentioned in the last chapter, you can only
get good results with 3D visualization when you have lots of layers.
Now, run MODFLOW by clicking the calculator button on the toolbar. Answer
“YES” to the first prompt to create data files and then “NO” to the next prompt about
displaying the error file. After the model runs, import the results of the run. After
MODFLOW runs, run MT3D. Select Model/Use MT3D and then click the
calculator button. Select “YES” to create data files and then “CANCEL” to avoid
seeing the error file. After the MT3D run is finished, import the results for transport
step number , as shown below.
14 • Tutorial
Guide to Using GW3D
Click OK and you should see a contaminant plume displayed like the one below:
Launching GW3D
We will now view the contaminant plume in 3D using GW3D. Select 3D/Options
and the following dialog is displayed:
Guide to Using GW3D
Tutorial • 15
The options above tell GW3D to start a new image (Type of 3D View = Default) of
MT3D results (Model Type = MT3D). Make sure that the path to GW3D is correct.
If you installed the software using the default directory then this should be fine. The
last 3 options on the dialog tell GW3D to drape maps over the top of layer 1 but 10 ft
above the top of layer 1. The vertical exaggeration is 10. Click OK when you are
done reviewing these options.
Now, to launch GW3D, use 3D/Launch GW3D. Your screen should look like the
one below:
Yes, it’s not very interesting but we can fix that. The default view is just the shell of
the model shown in a light green and the base maps viewed from above, similar to
the plan view in Vistas. First, click the left mouse button on the image. This
16 • Tutorial
Guide to Using GW3D
activates the 3D viewing area. Now, click the 3D button on the toolbar. You can
now rotate the image using the mouse.
Start by clicking the right mouse button with the cursor over the image. Hold the
right mouse button down and move the mouse cursor toward the top of the screen.
This makes the image bigger. Now move the cursor to the lower left corner of the
image and press and hold the left mouse button. Move the mouse cursor toward the
top of the screen to rotate the image. It should look similar to the one below:
Showing Isosurfaces
The quickest way to view the contaminant plume is to select View/Isosurfaces. This
shows the plume as surfaces of equal concentration at 365 days (note the time on the
drop-down list on the toolbar to the left of the 3D button).
Guide to Using GW3D
Tutorial • 17
Change the time value from 365 to 3,650 by clicking on the drop down list of time
values and scrolling to the bottom. The plume at 3,650 days should look like the one
below:
GW3D just chooses some arbitrary values to contour in 3D. You can change the
concentration levels to show by selecting Options/Parameters and clicking on the
Isosurfaces tab. Click on the option to customize levels and enter the values of 1,
10, 50, 100, and 400 in the spreadsheet.
18 • Tutorial
Guide to Using GW3D
Click OK or Apply and the plume should now look like the one below:
Sometimes it might be difficult to see the inside of the plume with isosurfaces. One
way to see inside is to cut away part of the model area. Select Options/Parame ters
and click on the Subgrid tab. Change the minimum j value from 0 to 34, click on
the “Activate Subgrid” checkbox and click OK.
Guide to Using GW3D
Tutorial • 19
Now the screen should look like the following:
Solid Representation of the Plume
You can also view the plume as a colored solid block. Select View/Solid and the
image should look like the following:
20 • Tutorial
Guide to Using GW3D
Notice that the solid uses the same subgrid as you created for the isosurfaces. One
common option for solids, especially when viewing concentrations, is to remove the
very low concentration values. Select Options/Parameters and click on the Solids
tab. Click on the option to Apply Thresholds and change the minimum level to 1.
Click OK or Apply and the image should look like the following:
Guide to Using GW3D
Tutorial • 21
You should experiment with the “smooth”, “blocky”, and “banded” options for
display of solids on the dialog above. The blocky display is best for viewing model
input properties if they have been entered based on zones. Smooth is good for
continuously varying properties. Each gives the image a different look.
Working with Particle Traces
Go back into Groundwater Vistas and run MODPATH. Select Model/Use Modpath
and click the calculator button on the toolbar. Import the particle traces into Vistas
after you are done and your screen should look like the one below.
22 • Tutorial
Guide to Using GW3D
We will now use GW3D to view the results of a MODFLOW run with particle tracking from MODPATH. Select 3D/Options and change the model type to
MODFLOW. Click OK and then select 3D/Launch GW3D. Manipulate the image
as you did before right before we added the isosurfaces.
Now add isosurfaces for the heads computed by MODFLOW. Select
View/Isosurfaces and your screen should look like the one below.
The things that look like little blue rocks at the bottom of the model are the cones of
influence around two pumping wells.
To view the results of MODPATH in 3D, select View/Pathlines and GW3D will
draw the pathlines with the color corresponding to the travel time. Blue is at time
zero and red is at the maximum travel time.
Guide to Using GW3D
Tutorial • 23
You can also change the way that pathlines are displayed using Options/Parameters
and click on the Pathlines tab. You may change the way that the colors are selected,
the range of times to display, and also whether to display the pathlines as lines or
tubes. Tubes are thicker and easier to see.

Image Options
Introduction
Options for display of the various 3D features are provided in GW3D on the
Options/Parameters menu or by clicking the
button on the toolbar. A property
sheet with numerous tabs is displayed as shown below. The following sections in
this chapter document what each control represents.
Data
The Data tab determines what data type is displayed when you choose isosurfaces or
solids. Data types include head and drawdown for MODFLOW and concentration
for MT3D. In addition, any of the data types listed at the bottom of the 3D Options
dialog in Vistas are also contained on the drop-down list of data types. The latter can
include hydraulic conductivity, storage, leakance, recharge, etc. For those data types
that can be transient, such as head or concentration, there is also a time drop-down
list which shows all available times saved by MODFLOW or MT3D in the binary
output files.
At the bottom of the tab are the “Model Features” that can be displayed. These are
generally boundary conditions defined in Vistas such as constant heads, wells,
drains, etc. Click on the ones you want to display. You may also choose a color for
each boundary types. The Up and Down buttons chance the order in wh ich boundary
conditions are displayed.
26 • Image Options
Guide to Using GW3D
Isosurfaces
The Isosurfaces tab controls the contouring in three-dimensions. An isosurface is a
three-dimensional contour. The “calculated Z range” shows the range in the data
values for the data type to be displayed (see Data tab). The minimum level and
maximum level fields allow you to only show isosurface contours within a certain
range. The Number field is the number of isosurfaces displayed. If the Customize
Levels check-box in not checked, then the isosurfaces are equally spaced between the
min and max levels. On the other hand, if you check the box to customize levels,
you then enter each isosurface level in the spreadsheet below.
Guide to Using GW3D
Image Options • 27
The Scale section at the bottom of the Isosurface tab controls the exaggeration in all
three dimensions. Normally the X and Y scales are 1.0. The Z scale is the degree of
vertical exaggeration. A Z scale of 10 is good for many cases, but depends on the
relative difference between the X and Z dimensions of the model.
Solid
The Solid tab determines how solid color-flooded images are drawn in three
dimensions. The “calculated Z range” shows the range in the data values for the data
type to be displayed (see Data tab). The minimum level and maximum level fields
allow you to only show the solid image within a certain range of data values if the
Apply Thresholds check-box is checked.
There are three types of solid images that can be displayed. The default is smooth.
In the smooth solid image, the data values are interpolated in three-dimensions. A
blue color represents the lowest value and red represents the highest value and the
remaining colors are graded smoothly between the two extremes. In the blocky
image, the same colors are chosen; however, the colors are applied as a constant
color with each grid cell. Thus, for properties that vary discretely (such as those
defined in zones in Vistas), the blocky pattern is better than the smooth pattern. The
banded pattern, a contour-like effect is produced where band represents a contour
interval. The number of bands is also a user-defined parameter.
Guide to Using GW3D
Subgrid
The Subgrid tab allows you to only display a portion of the model domain. Any
information outside the subgrid is not displayed. The “i” dimension is the same as X
or the mo del columns. The “j” dimension is Y or rows and the “k” dimension is Z or
layers. Note that j and k dimesions are backwards from the way that
MODFLOW/MT3D number rows and layers. A value of k=1 is the bottom-most
layer of the model and a value of j=1 is the southern-most row.
To use the subgrid, enter values for i, j, and k at the top and then check the box
labeled “Activate SubGrid” in the center of the dialog.
Guide to Using GW3D
Map
The Map tab provides the mapping of real-world coordinate systems to the model
coordinate system. This information is passed automatically to GW3D from
Groundwater Vistas. The X and Y origin coordinates are the real-world coordinates
of the lower left corner of the model grid. Maps can be displayed as either draped
over the top of layer 1 or on a flat plane. If a flat plane is used, then an elevation of
that plane is also required and you may choose to “trim” the map to the limits of the
model grid. When the drape option is chosen, a “gap” is entered, which is the
distance between the top of layer 1 and the map lines that are drawn.
Guide to Using GW3D
Lighting
The Lighting tab allows fine adjustment of how the graphic objects are illuminated.
The default lighting is a “headlight” illuminating the graphic objects from the
direction of the viewpoint. This setting is usually adequate for most cases. However,
for fine adjustments, the headlight intensity may be decreased or completely turned
off (under the “Lights” tab). In addition, you may turn on an “auxiliary light” for
illumination from a direction specified by a vector whose x-y -z components may
vary from -1 to 1. For example, if x=1, y=0, z=0, the auxiliary light will shine from
the positive x axis towards the negative x axis.
Guide to Using GW3D
Surface
The Surface tab provides controls over the surface parameters of the graphic objects.
These parameters include:
• Diffuse:
• Ambient:
This parameters is currently not adjustable and is set to 1.0.
Increasing this parameter above 0 gives surfaces a "washed out" appearance and reduces the
shading. Setting this parameter to the maximum value of 1 causes surfaces to appear white.
• Specular:
The amount of reflected light,
• Specular Power:The surface shininess.
Guide to Using GW3D
Crop
The Crop tab controls cropping a solid or a set of isosurfaces. The cropping planes
are defined by normalized coordinate along the x, y, and z edges of the bounding box
(that is, they range from 0 to 1). These normalized coordinates are entered into the
boxes under “Min” and “Max” (under the “Controls” tab). Clicking the up or down
arrowheads increases or decreases the Max or Min value by the amount in the
“Delta” box. Checking the “Max = Min” option sets the Max value equal to the Min
value to display a two-dimensional slice. The “Options” tab provides the option to
display the outer shell of the cropped-away solid or the cropped-away isosurfaces.
The four sliders can be used to set the color and opacity of the cropped-away pieces.
There is also a color button to make selection of color easier.
Guide to Using GW3D
Shell
The grid shell is a semi-transparent surface showing the outside of the active model
grid. You may choose to turn off this shell and you may also add axis labels to show
the X, Y, and/or Z axes. The color of the grid shell may also be changed, either with
sliders to with a color button.
Guide to Using GW3D
Bar
A color bar may be displayed on the image to illustrate how the colors are mapped
from blue to red. The color scales are controlled, along with an option for a
logarithmic scaling. The parameters at the top of the dialog not only control how the
bar is displayed but also how colors are mapped to the data for isosurfaces and
solids.
Vector
Velocity vectors may be displayed on the image. The vectors are short lines that
originate at the center of a model cell and point in the direction of flow. The length
of the line is proportional to the velocity at that point. You may only display a
subset of the velocities (the threshold) and you can subsample the vectors to only
show every N vectors in the i (column), j (row), and k (layer) directions.
Guide to Using GW3D
Pathlines
Pathlines can be displayed as either lines or tubes. The only difference is that tubes
are thicker and are easier to see. The colors are mapped from blue at early time to
red at later times. You can control the values assigned to blue and red. You may
also only show portions of the pathlines by clicking on “Time Range” at the bottom
and then entering the minimum and maximum travel times to display.

Command Reference
File Menu
New
The New command on the File menu starts a new 3D image. You then need to select
File/Import to bring in the data and results for a MODFLOW or MT3D run. You
would normally not use this menu command, but rather use the command in
Groundwater Vistas (3D\Launch GW3D) to start a new 3D image.
Open
The Open command opens an existing GW3D document (*.gw3 extension) for
viewing. Only documents created by GW3D can be opened. If you try to read a file
that was created by a newer version of GW3D than you have, GW3D will display a
warning to that effect. All subsequent revisions to Version 1 are free to download.
Just go to our web site at www.groundwatermodels.com and log in.
Close
The Close command closes the current GW3D document. GW3D is a multdocument interface and can open as many documents as there is sufficient memory
for.
Save/Save As
The Save command saves the current image to a GW3D document.
Print, Print Preview, Print Setup
There are four menu selections related to printing the currently active view. These
include Print, Print Preview, Print Setup, and Page Setup. The first three options
are standard Windows menus and will work the same as your other Windows
applications. The current view can be printed to any printer, plotter, fax modem, or
other device supported by Windows. The only potential problem with printing is
related to the rotated fonts used in type curve and contour labels. Some Windows
38 • Command Reference
Guide to Using GW3D
device drivers do not properly support rotated fonts. It is very important to select
Print Setup and choose the option to “Print TrueType as Graphics”. Most Windows
device drivers will support this option, which allows for proper font rotation. If after
selecting this option the type curve and contour labels are not properly rotated, you
should call the manufacturer of your printer or other output device to get an updated
Windows driver.
Page Setup
Choose Page Setup to control the margins and scale on the printed output. You can
also use this menu to define headers and footers and select which ones will occur on
the printed output via the Page Setup Options property sheet.
Orientation
Portrait
When selected, the printed output uses the short
dimension of the paper as the x-axis and the long

Map Overlay
GW3D can import maps created by Groundwater Vis tas. These files have *.map
extension. You must be sure that the map file is in the proper coordinate system,
otherwise it will not display properly. In all cases, you should first go into
Guide to Using GW3D
Groundwater Vistas, create the map using the File/Map command in Vistas. Once
the map is displayed properly in GV, it can be displayed in GW3D for the same
model. If you launch GW3D from Groundwater Vistas, all map files being displayed
in Groundwater Vistas will also be displayed in GW3D.
Import
The Import command allows you to start a new 3D image from an existing
MODFLOW or MT3D simulation. Normally you would not use this command as it
is easier to launch GW3D directly from Groundwater Vistas to start a new image.
Export
The Export command creates three types of files, (1) a Windows metafile, (2) a
placable Windows metafile, and (3) a VMRL World file for viewing in a 3D
program other than GW3D. Simply supply a file name and GW3D will create the
file.
Export Animation
Animation. You simply specify the starting and ending simulation times at the top
of the dialog, a change to the Viewpoint if desired, and a file prefix for the files. In
addition, you specify a directory for the files. A series of images will be saved in the
directory with names in sequence. For example, if the file prefix is test, then the first
image will be test001.bmp, etc.
Guide to Using GW3D
Send
The Send command is used to email the current GW3D document using your default
email software. You should make sure to save the current GW3D document before
sending it.
Most Recently Used Files
The four most recently opened document files are listed at the bottom of the File
menu for easy access. Simply click on the appropriate file name in the menu and
that file will be automatically opened.
Exit
The Exit menu closes all open documents and exits the application. You will be
prompted to optionally save each of the currently opened documents that has
unsaved changes.
Edit Menu
Cut, Copy, Paste, Delete
The Cut, Copy, Paste, and Delete menus are standard Windows functions. Each
menu operates on the currently selected elements or spreadsheet lines. An element
can be a well, title, line, frame, legend, symbol, parameter, or scale. To select one
of these elements in a map view, simply move the cursor over the element until you
see the
arrow appear, then click the left mouse button. The element will turn a
solid color or a bounding rectangle will appear to identify that it has been selected.
Multiple selection is achieved by repeating the procedure while holding down the
Shift key. Now, all of the edit operations will work on this element. If no element
has been selected, these menus will appear in gray and cannot be used. One
exception is the Copy menu which allows copying the entire view to the clipboard as
an OLE object and a metafile.
To select lines in a spreadsheet view, click the left mouse button in the leftmost
column of the spreadsheet and drag a selection. Alternatively, hold down the shift
key and use the arrow keys or page keys to expand the selection.
Use Cut to remove the selected elements or spreadsheet lines from the view and put
them on the Windows clipboard. You may also use the
button on the Standard
toolbar to cut. Use the Delete menu to simply remove the elements or spreadsheet
lines from the view without placing them on the clipboard. Use Copy to keep the
elements or spreadsheet lines in the view but make a copy on the Windows
clipboard. You may also use the
button on the Standard toolbar to copy. You
may put clipboard elements into the current view using the Paste menu selection or
Guide to Using GW3D
the
button on the Standard toolbar. The items or lines are pasted back at the
same coordinates as the original elements or before the currently selected line of the
spreadsheet. These edit features are most useful to transfer elements from one
document to another. You may have several analyses open at one time and cut,
copy, and paste elements from one document to another.
During spreadsheet paste operations, the data is assumed to be in Windows text
clipboard format with Tab characters separating data values and a newline character
at the end of each data row. During spreadsheet cut and copy operations this same
format is produced. Additionally, the order of the values in the clipboard
corresponds to the order of the columns displayed on the spreadsheet. Since the
number of and order of columns on the spreadsheet can be adjusted make sure the
data matches the spreadsheet into which it will be pasted.
Select All
The Select All menu is used to highlight all elements in a particular category. A
third menu appears with the following categories: title, line, frame, legend,
parameter, or symbol. You may want to select all instances of a particular element in
order to cut/copy and then paste into another document.
Delete
The Delete menu deletes the currently highlighted row of the spreadsheet or the
currently selected block of rows. For a graph or map view, it deletes all selected
elements.
Map Items
The Map Items menu is activates the Map Items Information property sheet as
shown below. This menu selection is used to manually add, delete, or edit objects in
the currently active view. These objects include legends, lines, parameters, frames,
symbols, and titles.
The items are categorized by item type and individual items are identified based on
their primary X and Y coordinates. As discussed in the concepts section, the
coordinate system is scaled inches. All editing is done using the property sheet
specific to the item.

required. Click on OK and the new name will be saved. The required information
can then be entered into the input section of each box.
Information entered in these fields can be accessed in footers/headers, figures and
parameter boxes displayed on graphical output.
3D Manipulation
There are three options on the 3D Manipulation menu which determine how the 3D
image is panned, zoomed, and/or rotated. Joy stick and mouse mode turn on the
ability to manipulate the image. The Off option eliminates the ability to change the
image using the mouse or joystick. When you first start GW3D, 3D Manipulation is
in the Off mode. You can quickly turn on mouse mode by clicking the 3D button on
the toolbar.
Reset, Save, Recall Viewpoint
The “Save Viewpoint” command saves the current viewpoint. The saved viewpoint
may be restored by using the “Restore Viewpoint” command. Note that the
viewpoint is saved only temporarily and is discarded when the program terminates.

Automatic Refresh
The Automatic Refresh menu selection determines whether GW3D will redraw the
window each time a dialog or property sheet is displayed or the window is resized,
zoomed, or changed in any way. A checkmark appearing next to Auto Refresh
means that the display is redrawn after every action that changes the display. Click
on this menu to toggle the option on or off (with or without the checkmark). The
default condition is Auto Refresh on. You may want to turn Auto Refresh off if
you are making a lot of changes and your image is complex. On a fast computer, the
refresh is fast enough that you probably will not care.
Refresh
Selecting Refresh from the View menu causes the map window to be redrawn. You
would use this feature if you have turned the Auto Refresh off (see last section) and
the screen needs to be redrawn after a scroll or other action. You may also use the

Set Projection To
The Set Projection to menu sets the projection mode to perspective or parallel. In
perspective mode, parallel lines appear to converge to a point at infinity. This is the
default projection mode. In parallel mode, parallel lines appear to remain parallel to
each other as they extend to infinity. Parallel projection is of limited usefulness in
three-dimensional visualization, but can be used to align grid nodes or to compare
vector lengths.

About GW3D
The About GW3D displays the About GW3D dialog as below. This dialog presents
the program version number, credits and identifies the operating system the
application is running on.
Guide to Using GW3D
The Register button, when clicked, is used to register the software by displaying the
GW3D Registration dialog as below. The dialog displays a System Code which can
be copied to the clipboard (you do this by highlighting the system code and pressing
Ctrl-C) and pasted into an email to be sent to [email protected]. We
will reply with a security code that you paste or enter into the Security Code field in
the above dialog. Alternatively, you can get a security code by calling either ESI in
the United States at (610) 670-3400 or ESL in the United Kingdom at +44 1743
280020; however, it is strongly recommended that the transaction be done via email
since the codes are rather long.
Security Code:
This is an encrypted code containing information about your software license
and the configuration of the computer used to validate the license
Authorization Level:
The level of functionality of the application granted by the license
System Code:
This is an encrypted code containing information about your hardware
configuration used to generate a unique Security Code
