 TOUR                                                              Menu: SOLID
 =============================================================================
 Interactive manipulation of the display of the surfaces and shading model
 with an option to save the current view as a screen bit-map.
 (Applicable to solid mode only).

      1.   (CHAR) file name (3 char.) for picture taking (p-key) <pic>

 Description

 This command invokes a special display mode where you
 may view your model from any point, walk in and around it, view it
 in perspective, and with shaded surfaces, etc.

 The view (by default) fills the whole screen. The pull-down
 and side-bar menus disappear. The screen background is changed to
 blue (default). The screen status, including the RGB background color
 mix, the angle of the site cone and the whether the current display
 is at an automatic or fixed scale, is displayed at the top of the
 screen.


 The model is displayed in the most recent solid view
 (axonometric view is the default) with colored surfaces.

 A menu (which may be removed) appears across the bottom
 of the screen, with the input character required for the option indicated
 in a different color.

 A small cube, with the three main axes indicated, appears
 on the top-right of the screen and moves dynamically with every movement
 of the mouse (or direction keys). When you have positioned the cube
 in the orientation in which you wish to view the model press <ENTER>
 and the model will be redrawn to the new orientation.

 You may freeze any view as a screen bit-map by pressing the key `p'
 (see command \pic). When doing this you are asked to provide a
 file name for saving the pictures. The default is PIC. While the system
 is saving the picture the cube at the top right corner of the screen
 disappears. The file name is suffixed by number for consecutive savings.
 The picture may be recalled by the `s' option of the \pic command.



 To Manipulate the View

 The orientation of the view is controlled by the numeric
 keypad (on the right of your keyboard), by the mouse or digitizer.
 Every time you press one of the direction keys the small cube frame
 in the corner of the screen will rotate by five degrees in the direction
 selected. When the orientation of the cube resembles the orientation
 of the view of the model that you want, press <ENTER> and the model will be
 redrawn to that orientation.

 To change background color (depending on your display type):

  8   Adds Red to background
  9   Adds Green to background
  0   Adds Blue to background.

 The following keys are used for special effects and functions:

 Key       Function

 1          Shading in white (monitors supporting 256 colors only).
            Surfaces in white (other color monitors).

 2          Shading in red (monitors supporting 256 colors only).
            Surfaces in red (other color monitors).

 3          Shading in blue (monitors supporting 256 colors only).
            Surfaces in blue (other color monitors).

 4          Shading in green (monitors supporting 256 colors only).
            Surfaces in green (other color monitors).

 s          For monitors that support 256 colors only, press s to obtain full
            shading in original colors.

 Shift+s    Shading in original colors (monitors supporting 256 colors only).
            Surfaces in original colors (other color monitors).

 h          Removes hidden lines.

 c          Displays original colors without shading. (You may
            restore shading by pressing 1, 2, 3, or 4.)


 f          Moves the eye forward toward the object (perspective)
            by one unit (Meters or Feet).

 b          Moves the eye backward from the object (perspective)
            by one unit (Meters or Feet).

 Shift+f    Decreases the distance between the eye and the target
            by half (perspective).

 Shift+b    Increases the distance between the eye and the target
            to twice the current distance (perspective).

 Shift+a    Automatic scale. The model will fill the screen irrespective
            of forward/backward movements of the eye and target.

 Shift+n    Fixed scale. The size of the model on screen will change
            according to the forward/backward movements of the eye and target.

 a          Moves both the eye and the target forwards by one unit (Meters or
            Feet).


 r          Moves both the eye and the target backwards by one
            unit (Meters or Feet).

 t          Places the target in the middle of the model.

 Shift+m    Moves the target to the middle of the model.

 Shift+l    Moves the target to the left by 5.

 Shift+r    Moves the target to the right by 5.

 Shift+o    Opens the sight cone in perspective by 5. The default when
            entering the module is 70.

 Shift+c    Closes the sight cone in perspective by 5. The default when
            entering the module is 70.

 <ENTER> or * ("pick") or ("snap")
            Press any of these three keys to redraw the model,
            after making changes to the viewing conditions.

 p          Saves the current display as a screen bit-map under the name
            specified at the start of the command.

 Caps Lock + Num Lock
            Terminates the screen refresh. To resume work (either within this
            command or in another command) press these two keys again.

 Ctrl + Num Lock
            Temporarily halts the screen refresh. Press any key
            to continue the refresh.

 x          Displays the axonometric projection.

 v          Restores the orientation of the cube to the current
            orientation of the model.

 m          Toggles the menu on/off the screen.

 e          Exits from the shading module. It will return you to
            the model editor screen, restore original colors, and redraw the
            model in the current display mode.

 NOTE:If options `s' or `d' in the \dsmod command have not been used on this
 model, prior to using \tour, the system processing may take some time,
 depending on the complexity of the model.
