         LINE UNITS                                            LINE UNITS

            Summary: Used to select or change the distance the
                     graphics cursor will move each time you press a
                     cursor key when using the DRAW or MOVE PEN
                     commands.

            Menu(s): UNITS

          Procedure: A menu will appear containing a list of drawing
                     increments for you to choose. A message will
                     display your current Line Unit in the upper
                     left-hand corner of the screen.

                     You must choose a Line Unit, even if its the same
                     unit currently being used in order to return
                     to the Draw Menu.

                     Your choices are:

                     1, 2, 3, 4, 5, 10, 20, 25, 50, 100, 250, 500, 1000

               Note: While using the DRAW or MOVE PEN commands, the F9
                     KEY can be used to set the LINE UNITS as well. For
                     more details see the F9 KEY command.

         MAIN MENU                                              MAIN MENU

            Summary: The first menu to appear when starting Image-3D.
                     The menu contains the commands to begin a drawing
                     session as well as program configuration.

            Menu(s): MENUS MENU, and when first starting the program.

          Procedure: The first menu to appear in Image-3D is the Main
                     Menu. The commands listed refer mostly to the
                     operating control and setup of Image-3D.

                     IMAGE DRAW starts a drawing or editing session
                     using files from the DRAWINGS file directory.

                     SETUP FILE creates a new drawing template file.

                     VERSION displays distribution information for
                     Image-3D Version 1.8.

                     TRANSLATE is a command to convert V1.8 files to
                     Versions 1.5 or 2.0 of Image-3D.

                     SAVE CONFIG saves the Disk Drive and/or Path
                     setting for the location of Drawing Files.

                     DRAWINGS allows you to set the Disk Drive or
                     Directory Image-3D will use to read and write your
                     drawing files.

                     QUIT ends the Image-3D program.

                     When MAIN MENU is selected from a drawing or
                     editing session, the program will ask you if you
                     would like to save your drawing before returning to
                     the Main Menu.

                     YES will save your current drawing on disk. You
                     can't save your drawing from the Main Menu, so this
                     is the last chance to save your drawing before
                     ending the program or starting a new drawing.

                     NO will not save your file and all changes made
                     since you last issued the SAVE IMAGE command will
                     be lost. If you didn't use SAVE IMAGE while you
                     were in a drawing session, then the entire file
                     will not be saved.

         MENUS                                                      MENUS

            Summary: Displays the names of the four primary menus
                     used in Image-3D: View Menu, Edit Menu, Draw
                     Menu, and the Main Menu.

            Menu(s): DRAW MENU, VIEW MENU, EDIT MENU

          Procedure: Select the primary menu you would like to have
                     displayed. Each menu title corresponds to the type
                     commands that will be found on that menu.

         MOVE                                                        MOVE

            Summary: Displays the Move Menu, where you can move your
                     Image in any of six directions and by a number of
                     different unit increments.

            Menu(s): VIEW MENU

          Procedure: By selecting MOVE from the View Menu, the Move Menu
                     appears and displays the current Move Unit in the
                     lower right-hand corner of the screen. You can move
                     your Image Left and Right (X-Axis), Forward and
                     Backward (Y-Axis), and Up and Down (Z-Axis).

                     Choosing any of these six directions will cause the
                     Image to be recalculated and displayed in the new
                     position. The amount of movement is set by
                     selecting either the 200, 500 or 1000 Units from
                     the menu, or by using the SPECIFY command to enter
                     your own increment in the range of 1-1500 units.

               Note: The program calculates your viewpoint using the
                     center coordinate 0,0,0. Centering your image with
                     the MOVE command allows you to have a more equal
                     rotation and tip transformation. This will prevent
                     major portions of your image from being rotated out
                     of view. To center your image, use Orthographic
                     views such as a front view, top view or side view
                     (F1-F6 KEYS). And the Axes Grid (F8 KEY) is also
                     very useful.

               Note: The graphics cursor remains at the current
                     coordinates and does not MOVE with your Image.

         MOVE PEN                                                MOVE PEN

            Summary: Allows you to move the graphics cursor without
                     drawing a line.

            Menu(s): DRAW MENU

          Procedure: After selecting MOVE PEN, use the LEFT, RIGHT,
                     UP, and DOWN cursor keys to position the graphics
                     cursor. The position you choose will become the
                     starting point for the next line you draw with
                     the DRAW command.

                     Use the HOME key to toggle between the three
                     drawing planes to control your movement in 3D
                     space. Like the DRAW command, LINE UNITS is used to
                     set or change the increment the graphics cursor
                     will move each time one of the cursor keys is
                     pressed. Also you can set the LINE UNITS while the
                     MOVE PEN mode is active by using the F9 KEY.

                     When you have the graphics cursor positioned, press
                     the ESCAPE key. Cursor key control will now
                     pass back to the Draw Menu where you can begin
                     selecting commands again.

         NORMAL                                                    NORMAL

            Summary: Sets the viewport back to normal after having
                     used the SMALL or LARGE command.

            Menu(s): ENLARGE

          Procedure: The viewport returns to its normal setting, your
                     image is redrawn, and the primary menu where you
                     issued the ENLARGE command is redisplayed.

         PLAN VIEW                                              PLAN VIEW

            Summary: Displays three Orthographic views, in addition to
                     the current 3D viewpoint, using Full Screen Mode.

            Menu(s): VIEW MENU

          Procedure: The screen is cleared and is divided into four
                     equal sections. In each section a different view
                     of your image will be drawn. Three of the views
                     are Orthographic views, which are "straight on"
                     views of your image. The fourth view will
                     be the same view that was previously displayed
                     when you selected this command.

                     The top-left display is the Top View.

                     The bottom-left display is the Front View.

                     The bottom-right display is the Right Side View.

                     The top-right display is the current 3D viewpoint.

                     Like the FULL SCREEN command, this screen is
                     another good location where a memory resident
                     screen printing program can be used.

                     After viewing your image with PLAN VIEW, press any
                     key and you will return to the normal viewport and
                     View Menu.

               Note: If the Axes Grid is On, it will be temporarily
                     turned off for this command.

         PREVIOUS                                                PREVIOUS

            Summary: Returns you to the previous menu or to the
                     previous primary menu.

            Menu(s): Almost all of them.

          Procedure: To move from one menu to another you must
                     select a command or menu title from a currently
                     displayed menu.

                     In some cases, such as Line Units, you will return
                     immediately to the Draw Menu once you make a menu
                     selection. In other cases, such as the Scale Menu,
                     a specific menu title appears in the menu list
                     (i.e. Scale Type) to redirect your menu control.

                     However, some commands like ENLARGE or COLORS can
                     be performed on either the View, Draw, or Edit
                     Menus. In these cases, PREVIOUS will return you to
                     the primary menu where you selected the command.

         QUIT                                                        QUIT

            Summary: Ends Image-3D.

            Menu(s): MAIN MENU

          Procedure: After selecting QUIT, you will be prompted to
                     confirm your selection.

                     NO will return you to the Main Menu.

                     YES will end the Image-3D program and you
                     will be returned to DOS.

         SAVE CONFIG                                          SAVE CONFIG

            Summary: Saves the DRAWINGS specification in a file on disk
                     and is used each time Image-3D is run.

            Menu(s): MAIN MENU

          Procedure: Image-3D Version 1.8 supports the use of a Disk
                     Drive and path specification for your Drawing
                     files. The configuration can be set by using the
                     DRAWINGS command.

                     Once you've set up the program configuration using
                     this command, issue the SAVE CONFIG command to save
                     the setting on disk. Image-3D saves the setting in
                     the file named: IMAGE-3D.SET. Each time Image-3D is
                     run this setting will be displayed on the Main Menu
                     Screen.

               Note: The Library setting is not applicable to Version 1.8

               Note: If you have a write protection label on the Image-3D
                     system disk, temporarily remove it for this command.

         SAVE IMAGE                                            SAVE IMAGE

            Summary: Saves your drawing and all current settings on
                     disk.

            Menu(s): DRAW MENU, VIEW MENU, EDIT MENU

          Procedure: Selecting SAVE IMAGE will save your Image on disk.
                     The file will have the name you specified when you
                     started drawing or editing, and will also have the
                     extension ".3DM". All your current settings will
                     also be saved including the current location of the
                     graphics cursor.

                     After your Image has been saved, press any key and
                     you will resume control of the menu selector.

               Note: Your drawing is saved as numerical data and not as a
                     memory image of the screen. The size of the file
                     will be directly related to the number of lines you
                     have in your drawing. Should you ever create an
                     image with the maximum amount of lines (3000) the
                     file will require around 100K bytes of disk space.

         SCALE                                                      SCALE

            Summary: Leads you to the Scale Menu, where you can increase
                     or decrease the size of your Image. You can also
                     scale each Axis independently.

            Menu(s): VIEW MENU

          Procedure: By selecting SCALE from the View Menu, the Scale
                     Type Menu appears with four menu choices: ALL
                     SIDES, HEIGHT, WIDTH, LENGTH. You must select one
                     of these options. After selecting a Scale Type the
                     Scale Menu will appear and display the current
                     Scale Factor in the lower right-hand corner of the
                     screen.

                     To change your Scale Factor, select from the menu
                     one of the following: .99, .95, .90, .75, .50.

                     The SMALLER and LARGER commands will scale your
                     Image using the Scale Type you selected and by the
                     Scale Factor currently displayed. Your Image will
                     be recalculated and then redrawn on the screen. You
                     can continue to scale your Image or return to a
                     previous menu using either the SCALE TYPE or the
                     PREVIOUS commands listed in the menu.

               Note: Like the MOVE commands, the graphics cursor remains
                     at its current coordinates and does not SCALE with
                     your Image.

               Note: Scaling your Image down to a tiny dot on the screen
                     will run the risk of setting some of the x,y,z
                     coordinates to zero. If this happens you may be
                     unable to bring your Image back up to its normal
                     size or shape.

               Note: Scaling your Image 2 to 3 times larger than the
                     viewport will run the risk of your image hitting
                     the "edge of 3D space" (+ or - 7,000 units). The
                     coordinates of your image will begin to reset to +
                     or - 7,000 and alter the shape of your image.

         SCALE TYPE                                            SCALE TYPE

            Summary: Returns you to the Scale Type Menu, where you select
                     the type of scaling you want to perform. ALL SIDES,
                     HEIGHT, WIDTH, or LENGTH.

                     menu when you first select SCALE from the View
                     Menu.

          Procedure: The Scale Type Menu allows you to select different
                     types of scaling:

                     ALL SIDES scales all the sides of your drawing at
                     once.

                     HEIGHT allows you to scale your image taller or
                     shorter.

                     WIDTH fattens or trims the width of your image.

                     LENGTH will allow you to lengthen or shorten your

         SETUP FILE                                            SETUP FILE

            Summary: Creates a new drawing template that is used each
                     time you start a new drawing.

            Menu(s): MAIN MENU

          Procedure: A short menu appears with the options: NO and YES.
                     A message will also appear that reminds you about
                     the function of this command.

                     SETUP FILE allows you to use one of your drawing
                     files, that has the settings you like, as a new
                     drawing template. Each time you begin a new
                     drawing, Image-3D loads the settings that are in
                     the file: SETUP.TMP.

                     SETUP FILE will transfer the following settings from
                     your selected drawing file to SETUP.TMP:

                     Line Unit, Move Unit, Scale Unit, XYZ VP Axes
                     Degree Increment, Your Current XYZ Viewpoint,
                     Currently Selected Drawing Plane, Background &
                     Foreground Color Selections.

                     If you do not want to create a new template file,
                     then select NO and you will return to the Main Menu.

                     Selecting YES will clear the screen, display a
                     listing of the drawing files from the disk or
                     directory currently set for your drawing files, and
                     prompt you for a filename. If you discover the file
                     you want to use is not listed, or you want to
                     cancel the command, then press ESCAPE and you will
                     return to the Main Menu.

                     If the desired file is listed, then enter its name
                     (without the ".3DM" extension). Image-3D will read
                     your file and then update SETUP.TMP. After this is
                     performed, press any key and you'll return to the
                     Main Menu. Each time you start a new drawing, the
                     new settings you just transferred will be used.

               Note: If you have a write protection label on the Image-3D
                     system disk, temporarily remove it for this command.

          Procedure: The viewport will divide into nine quadrants.
                     Choose the menu option that corresponds to the
                     quadrant you want to enlarge.

                     After making a selection, the viewport will be
                     redrawn to display only the area in the selected
                     quadrant. You will be returned to the menu where
                     you issued the ENLARGE command.

                     If you were already viewing an enlarged quadrant
                     when you selected SMALL, the screen will be redrawn
                     in order to display all 9 areas. You can select a
                     new area or use the PREVIOUS command to make no
                     change to your selected viewport. You can also
                     switch from SMALL to LARGE without having to use
                     the NORMAL command.

         SMALLER                                                  SMALLER

            Summary: A scaling command that reduces the size of your
                     Image using the Scale Type you've chosen and by the
                     current Scale Factor.

            Menu(s): SCALE MENU

          Procedure: The program will recalculate your drawing data and
                     then display your scaled Image. The degree of
                     scaling will be dependent upon the Scale Factor
                     being used.

                     After selecting the command you will remain in
                     the Scale Menu where you can continue with another
                     operation.

                     when moving your Image.

            Menu(s): MOVE MENU

          Procedure: The menus are not long enough to contain all the
                     needed increments so the SPECIFY command allows you
                     to enter your own. You may enter a Move Unit
                     increment between 1-1500 units.

                     Selecting SPECIFY will display "Move By How Many
                     Units (1-1500):" in the top row of the display.
                     Enter the number you would like the Move Unit
                     increment set to. To cancel the command and make no
                     change to the currently selected Move Unit, press
                     ESCAPE.

                     After you've entered your new increment, it will be
                     displayed below the Move Menu. Any subsequent Move
                     commands will move your Image by the number of
                     units indicated.

                     previously drawn line for editing. When you select
                     STEP EDIT, the first line of your Image will be
                     redrawn using an Editing Line Style which allows
                     you to find it in your drawing. Then press a key
                     other than RETURN and the Line Style will advance
                     to your next line. Continue pressing a key and the
                     Editing Line Style will step through every line in
                     your Image.

                     A message at the top of the screen will keep you
                     updated about your line count and how many lines
                     you've stepped through. When the line that you want
                     to edit is redrawn using the Editing Line Style,
                     press RETURN.

                     You can now use the DELETE LINE or LINE EDIT
                     commands to edit your selected line.

                     Stepping through your Image without choosing a line
                     will not cause a selection to take place. If you
                     want to cancel the STEP EDIT function once you've
                     started through your drawing, you can press the
                     ESCAPE key. The Image will be redrawn but no change
                     or selection will have occurred.

            Menu(s): DRAW MENU, VIEW MENU, EDIT MENU

          Procedure: The graphics display used by Image-3D with the
                     Color Graphics Adapter is the 640 x 200 Black and
                     White mode. By default, Image-3D draws your image
                     with White lines on a Black background. SWITCHCOLOR
                     allows you to "switch" these colors and draw Black
                     lines on a White background. Using SWITCHCOLOR
                     again changes the colors back to White on Black.

         TOP-BOTTOM                                            TOP-BOTTOM

            Summary: While using the DRAW or MOVE PEN commands, selects
                     the drawing plane that is associated with the Top
                     or Bottom Side of your image. (the X-Y Plane)

            Menu(s): NONE - Selected Only in DRAW or MOVE PEN commands.

          Procedure: While in either the Drawing Mode or the Pen Movement
                     Mode, you can toggle your drawing plane using the
                     HOME cursor key. A message in the upper right-hand
                     corner of the screen indicates your current
                     drawing plane.

                     The Top-Bottom drawing plane will cause any
                     subsequent movement of the graphics cursor to move
                     in relation to this plane and your viewpoint.

                     The LEFT and RIGHT cursor keys will move the
                     graphics cursor along the width of your image (the
                     X-Axis), while the UP and DOWN cursor keys will
                     move the graphics cursor along the length of your
                     image (the Y-Axis).

                     The current Z coordinate value (the location along
                     your image's height) will be locked in place as you
                     draw on the Top-Bottom Plane. To move along the
                     height of your image, you can use the FRONT-BACK or
                     LEFT-RIGHT drawing plane.

         TRANSLATE                                              TRANSLATE

            Summary: Changes the format of a file saved by Version 1.8
                     to a format used by Versions 1.5 or 2.0.

            Menu(s): MAIN MENU

          Procedure: Version 1.8 uses an upgraded file format that
                     differs from earlier versions. If you have a file
                     that you will be giving to someone with an earlier
                     version of Image-3D, specifically Version 1.5 or
                     2.0, this command will translate a 1.8 file to
                     their format.

                     After selecting TRANSLATE you will be prompted if
                     you want to translate a file. Selecting NO will
                     return you to the Main Menu. Selecting YES will
                     clear the screen and display the files on the
                     DRAWINGS Disk Drive or directory. You will be
                     prompted to enter the name of the file you wish to
                     translate. To cancel the command, press ESCAPE.

                     Once you've entered the name of the file, it will
                     be translated into the earlier format and saved.
                     Version 1.8 will still be able to load the file.

               Note: The file is saved using the same filename, so you
                     may want to make a copy with a different filename
                     before using this command.

               Note: Version 3.0 uses the new file format and can
                     readily read files created by Version 1.8 and vice
                     versa.

               Note: All the PC Libraries I've submitted Image-3D
                     have received or will be receiving Image-3D Version
                     1.8 for their program directory (end of May 87), so
                     this command may soon become obsolete.

         WIDTH                                                      WIDTH

            Summary: A Scale Type option that indicates you want only
                     the width of your Image scaled.

            Menu(s): SCALE TYPE

          Procedure: By selecting SCALE from the View Menu, the Scale
                     Type Menu will be displayed. You must choose the
                     type of scale operation you want to perform.

                     WIDTH means you want only the width (X-Axis)
                     scaled.

                     After you choose WIDTH, the Scale Menu will
                     appear and from this menu you perform the scaling
                     operations.

         XYZ VP                                                    XYZ VP

            Summary: Used to select your viewpoint around your Image.

            Menu(s): DRAW MENU, VIEW MENU, EDIT MENU

          Procedure: The viewport clears and displays an XYZ Axes. The
                     current degree of Rotation and Tip of your
                     viewpoint is displayed on the right-hand side of
                     the screen, as well as the currently set Axes Unit
                     increment.

                     The Axes are labeled with a letter that corresponds
                     to the sides of your image, L (left), R (right),
                     T (top), F (front), B (back). These labels
                     will help you track your viewing position.

                     Using the LEFT, RIGHT, UP, DOWN cursor keys you can
                     rotate and tip the Axes. The LEFT and RIGHT cursor
                     keys rotate your viewpoint, the UP and DOWN keys
                     raise or lower (Tip) your viewpoint.

                     The rule to remember is: You Are Moving Your
                     Viewpoint, Not Your Image. Therefore, when you
                     press the RIGHT cursor key you will move your
                     viewpoint to the right, and the Axes will actually
                     spin to the left.

                     When you have selected your viewpoint, press RETURN.
                     Your image will be recalculated and displayed using
                     your new viewpoint.

               Note: The degree of movement the Axes rotates and tips
                     each time you press a cursor key can be set using
                     the AXES UNITS command or the F9 KEY while you're
                     using the XYZ VP command.

               Note: If you have a currently enlarged viewport (SMALL or
                     LARGE) you may need to select a new quadrant, since
                     the image rotates on the point 0,0,0 and the area
                     you were viewing may have been rotated out of view.

           See Also: F9 KEY, AXES UNITS

         REGISTERED USER
         ---------------

         For users who discover they like Image-3D and would like to
         receive Version 3.0 and stay informed of further enhancements,
         I invite you to consider becoming a Registered User. I also
         encourage those who have any suggestions to send them to me,
         since new ideas and comments will be helpful in making Image-3D
         the best program it can be.

         Version 3.0 contains these extra features:

         *** Perspective Mode:

         Turn On the Perspective Mode and Image-3D will display
         your drawing using 3-Point Perspective. This feature
         makes your images appear even more realistic, since
         parallel lines will slope toward vanishing points on the
         horizon. Additionally, you can control the observation
         distance of your viewpoint as well as an imaginary window
         through which you are viewing your Image.

         *** Control Objects Independently:

         In each drawing control up to Ten designated objects
         independently. Move, Scale, Edit, even Extract an object to a
         separate file for later use. You supply the name of the object,
         from then on the name of the object will appear in the menus
         whenever needed. And objects can be anything from One line to
         an entire building or even an entire block of buildings.

         *** Extract objects, Create a Graphics Library:

         You'll never have to draw an object twice again. The EXTRACT
         command will make a copy of any of your objects and save it on
         disk. This allows you to create an entire library of graphic
         elements and objects which you can use over and over again. You
         just choose one of your objects from the menu, give it any
         filename you like and Image-3D will create a new file
         containing your selected object. You can also extract your
         entire drawing if you like.

         *** Merge Files and Graphic Libraries:

         When you need an object or graphic element from your library,
         or perhaps an entire drawing, you can retrieve it from disk and
         load it into the drawing you're working on. It will merge with
         your drawing as one of the separately controlled objects so
         you can move and scale it into your desired position. Together
         with the EXTRACT command, the MERGE command will greatly reduce
         the time required to draw your images as well as increase your
         ability to construct more creative and elaborate 3D drawings.


                                                              continued



                                       64







         *** Combine Objects:

         Once you've positioned your objects the way you want them, or
         you've created a new object by placing graphic elements
         together from your library, the COMBINE command will let you
         designate this new group of objects as one new independent
         object. And once objects are combined, their old object
         designations become free to be used for yet other new objects.

         *** Circles, Spheres and Cones:

         Included with Version 3.0 are library files containing circles,
         spheres and cones. There are three circle files (a circle for
         each drawing plane), three files of spheres (each varying in
         the level of detail), and six cone files (a cone facing in each
         direction). You will be able to control them like any other
         object and you can create ellipses with them by scaling their
         sides independently.

         *** More Features:

         Draw in Five different Line Styles, support for separate
         Drawing File and Library File Directories, new primary menu
         with the commands used most often to "Build" your Images, and
         finally both the EGA or CGA Versions are now in one complete
         program, so you can configure Version 3.0 for either adapter.

         You will also receive the Version 3.0 Manual (on disk) and the
         phone number to call for Technical Support or Information you
         may want about the program. Also, as a Registered User you will
         receive update information on all future releases of Image-3D
         as well as companion modules as they are developed in the
         future.

         To become a Registered User, I request that you send me a
         contribution of $25. Include your Name and Mailing Address, and
         to assist me in the development of extra features please
         indicate which Display Adapter you are using (CGA or EGA) and
         the total Memory you have in your computer (512K - 640K).


              My address is:  Paul Luby
                              3117 W. Holland Ave
                              Fresno, CA  93722


         Note: The system requirements for Image-3D Version 3.0 are the
               same as Version 1.8.

         GLOSSARY
         --------

         CAD

         An acronym for "Computer Aided Design"

         CGA

         Color Graphics Adapter. Image-3D (in CGA mode) uses the 640 x
         200 Black and White Mode for drawing.

         Coordinates

         The set of dimensional values that specify a location in 3D
         space. Listed in the form: X,Y,Z. (X-Axis location, Y-Axis
         location, Z-Axis location)

         EGA

         Enhanced Graphics Adapter. Image-3D (in EGA mode) uses the 640
         x 350 16 Color Mode for drawing.

         Geometric Modeling

         The method of building an object by combining other completed
         shapes together, such as cubes, squares, and circles.

         Graphics Library

         A concept in which graphic elements such as circles, cubes,
         cones, etc., as well as complete objects like buildings, signs,
         etc., are stored in individual files and retrieved whenever
         needed. Thereby eliminating the need to redraw the object or
         graphic element more than once.

         Isometric View

         A three-dimensional view in which perspective is not used.
         Parallel lines will are drawn parallel and objects of equal
         size or height will appear equal no matter what their
         distance is from a viewpoint.

         Line Data

         The numerical information about a line's x,y,z coordinates and
         color.

         Orthographic View

         A two-dimensional view such as a Top View or Front View. The
         view is obtained by using a viewpoint that is perpendicular to
         the side of the object. Image-3D uses Orthographic views
         in the PLAN VIEW command and F1-F6 KEYS.

                                                              continued

         Palette

         A set of user selected colors.

         Perspective View

         A type of view in which elements of an image resemble their
         true distance and position. For example, parallel lines slope
         toward a vanishing point located on the horizon, and a row of
         objects equal in height will appear smaller the farther they
         are from the viewer.

         Pixel

         The smallest element on the monitor. Used to construct lines
         or letters. For example, the EGA has a horizontal resolution of
         640 pixels with a vertical resolution of 350 pixels.

         Rotation

         The turning of an object in a horizontal circular motion.

         Scaling

         The turning of an object in a vertical circular motion.

         Viewport

         The active drawing area where an image is displayed.

         Wire Frame

         Term used to describe a modeling technique in which a
         three-dimensional image is completely transparent. Lines are
         used to represent surfaces and edges.

         ERROR MESSAGES
         --------------

         Similar to a few other non-error messages displayed by
         Image-3D, Error Messages are also followed by the phrase "Press
         Any Key." This indicates that the program has paused
         temporarily in order for you to evaluate the error message and
         its possible cause.

         The following is a list of error messages used in Image-3D. In
         a number of cases, error messages were designed to correspond
         to similar error messages used by DOS. Others, however, are
         more specific for either your benefit or mine in order to track
         down the cause and solution of a problem.

         Bad Filename

              The filename contains characters that are invalid.
              Consult your DOS manual. Also, remember not to
              include the ".3DM" extension when Image-3D prompts
              you for a filename.

         Device Fault
         Device Timeout

              For users who are using DOS's supplied screen printing
              utility, these errors can occur if your printer is not ON
              (Device Timeout) or it stops running (Device Fault) after
              you've issued a PrtSc command. If you're using another
              screen printing program, it will likely have its own error
              messages.

         Device unavailable

              An attempt was made to access a device that is either not
              "on-line" or does not exist. For example, setting a
              directory specification to "C:" when in fact, a hard disk
              is not in the computer.

         Disk is full, unable to proceed

              Image-3D attempted to write a file on a disk which
              contains insufficient free space. Replace the disk
              with another that contains more free space and
              retry the command.

         Disk media error

              An attempt was made to write or read a file from your
              disk. This error indicates your disk may be defective.
              Consult your DOS manual for procedures to check your disk.




                                                              continued


                                       68







         Disk not ready

              An attempt was made to write or read a file from your
              disk. Check to be sure the drive door is closed properly.

         Disk write protect

              An attempt was made to save a file to your disk and
              encountered a write protect label, remove it and retry the
              command.

         File for new SETUP.TMP not found

              The drawing file you specified could not be found. Retry
              the command and be sure you are entering a filename that
              is listed in the directory.

         File: IMAGE-3D.SET not found

              This is the configuration file that contains information
              about your Drawing file Disk Drive or Directory. Image-3D
              must have this information in order to run properly.
              IMAGE-3D.SET file must be kept on the same disk as
              IMAGE.EXE. A new IMAGE-3D.SET file can be quickly created
              by configuring your program again, and using the SAVE
              CONFIG command.

         File: SETUP.TMP not found

              When starting a new drawing, the file: SETUP.TMP is loaded
              into memory and becomes the initial drawing template for
              your new drawing. SETUP.TMP must be kept on the same disk
              as IMAGE.EXE. If SETUP.TMP has been accidentally erased or
              destroyed, make a new copy from the original Image-3D disk
              or use the SETUP FILE command to create a new SETUP.TMP
              file.

         File to translate not found

              The drawing file you specified could not be found. Retry
              the command and be sure you are entering a filename that
              is listed in the directory.

         Image-3D files not found

              No drawing files were found on disk, or in the specified
              Directory or Drive for DRAWINGS.

         Internal error 101, 102, 103, 104, 105, or 106

              An internal error in the Image-3D program has occurred. I
              would greatly appreciate you sending me a description of
              the circumstances that has caused the error, the error
              number, and the actions the program took after it happened.

                                                              continued


                                       69







         Invalid Directory

              The directory specification is not correct. Check to be
              sure the proper syntax is being used, see the command:
              DRAWINGS. Also, Image-3D will not create a new directory
              if one doesn't exist. Use DOS to create new directories.

         Out of Memory

              There is insufficient free RAM. Check to be sure you don't
              have too many unnecessary memory resident programs
              currently in memory. Most Screen Printing Programs require
              less than 50K, so you should have enough memory to run
              Image-3D. If you have other memory resident programs in
              memory too, it may be necessary to remove some of them
              before running Image-3D.

         Out of paper

              For users who are using DOS's supplied screen printing
              utility, this error can occur when your printer runs out
              of paper before the screen has been printed. If you're
              using another screen printing program, it will likely have
              its own error messages.
