The Display menu is one of the standard menus and is available in all of the modules. The commands in the Display menu are used to control how attributes of a TIN, DEM, Feature Objects, etc., are being displayed, to set up a drawing grid, to control how contours are displayed, and to generate shaded images. The following commands are found in the Display Menu
- Display Options – Brings up the Display Options dialog.
- Contour Options – Brings up the Contour Options dialog.
- Grid Options – Brings up the Grid Options dialog.
- Refresh – When editing the image in the Graphics Window it occasionally becomes necessary to update the display or refresh the screen by redrawing the image. Whenever possible, WMS automatically updates the display. However, in several cases small parts may be obscured by editing procedures, and the display will need to be refreshed by selecting the Refresh command from the Display menu.
- NOTE: The process of redrawing can be aborted in many cases by pressing the ESC key.
- Frame Image – After altering the image display using the Zoom or Pan tools, the image can be centered by selecting the Frame Image command in the View menu. This command adjusts the window boundaries so that all currently visible objects just fit in the Graphics Window. It does not affect the viewing angle.
- View – a submenu with the following commands:
- View Angle – The objects in the Graphics Window can be rotated and viewed in three dimensions. Two angles, bearing and dip, are used to rotate the view. The bearing and dip values correspond to a rotation about the z and x axes. The bearing affects the horizontal angle (rotating the object in the xy plane), and the dip changes the vertical angle (shifting the viewing angle on the object to a higher or lower perspective). The object cannot be tilted sideways. Using only two viewing angles rather than three limits the viewing angles, but it is simpler and more intuitive. The bearing and dip angles can be explicitly defined in the View Angle dialog accessed by selecting the View Angle command from the View menu. The viewing angles can be manipulated interactively with the Rotate tool.
- Set Window Bounds – The region of the real world coordinate system that is mapped to the Graphics Window can be altered using the Pan and Zoom tools. It is also possible to precisely control the visible region by selecting the View | Set Window Bounds command from the Display menu. The Set Window Bounds dialog box appears and the x and y limits of the viewing area can be set.
- If the X range to be specified (preserves aspect ratio) option is selected, the x coordinate at the left and right and the y coordinate at the bottom of the Graphics Window are specified. The y coordinate at the top of the Graphics Window is not specified in order to maintain the aspect ratio.
- If the Y range to be specified (preserves aspect ratio) option is selected, the y coordinate at the top and bottom and the x coordinate at the left of the Graphics Window are specified. The x coordinate at the right of the Graphics Window is not specified in order to maintain the aspect ratio.
- If the X and Y range to be specified (alters aspect ratio) option is selected, the x coordinate at the right and left and y coordinate at the top and bottom of the Graphics Window are specified. Since all four coordinates are specified, the aspect ratio of the scene may be altered.
- Plan View – Selecting the Display | View | Plan View menu command, or the Plan View macro, changes the viewing angles so that the image is displayed looking down at the z-axis with the x-axis horizontal and the y-axis vertical.
- Front View
- Side View
- Oblique View – Selecting the Display | View | Oblique View command, or the Prespective View macro, restores the bearing and dip angles to their previously defined values and causes the image to be viewed from an oblique perspective. The Rotate tool can be used to alter the angle of view.
- Previous View – Selecting the View | Previous View command of the Display, or the View Previous macro, restores the Graphics Window viewing parameters to those in place before the last viewing command was issued (rotate, zoom, pan, etc.). A macro for this command appears in the Macro Tool palette.
- Z Magnification – Occasionally an object may be very long and wide with respect to its overall depth (z dimension). It is possible to exaggerate the z scale so that the variation in the z value is more apparent by selecting View | Z Magnification from the Display menu and changing the magnification factor to something larger than the default of 1.0.
- Open Hydrograph Plot – Brings up a Plot Window for the selected hydrograph.
- Plot Wizard – Launches the Plot Wizard.
