This Natural Regrade dropdown menu command allows the user to view the longitudinal profile of any polyline in the GeoFluv™ design and obtain the elevation and slope at any point along the profile.
Command prompt:
Select objects
The user places the cursor over the polyline that they want to inspect and left-clicks. The profile viewer appears on the screen. The user can move the cursor along the profile and the station, elevation, and slope information are displayed along the bottom of the dialog box at the position indicated by the cursor. Simultaneously, an arrow moves along the channel in the drawing pointing to the location along the longitudinal profile that the cursor is covering on the profile viewer.
Radio buttons for Vertical Exaggeration settings aid the user in evaluating low relief profiles.
Radio buttons also allow the user to toggle back and forth between Zoom and Pan drag action for the mouse. When set to Zoom, holding the mouse left-click button down while moving the mouse up and down will cause the viewer to zoom in and out on the longitudinal profile. When set to Pan, holding the mouse left-click button down while moving the mouse across the viewer will allow the user to pan around the longitudinal profile. Whether in Zoom mode or Pan mode, the middle mouse button can be held down to pan the profile in the display. Thus, if the user has a middle mouse button, staying in the Zoom mode and using the middle mouse button to pan is most efficient.
The Grid Ticks Only
toggle allows the user to see a grid on the profile display or to
see only tick marks on the axes.
The GeoFluv design made using Natural Regrade typically has many sub-watershed ridge and swale lines. The lines are 3D polylines and their profiles are generated from the user inputs (based on project area field work). The blue bar at the top of the View Longitudinal Profile pop-up dialog box will display the name of the line the user is viewing to supplement the visual dot-within-a-triangle that tracks along the line on the drawing.
The naming convention for the lines is to identify the sub-watershed, e.g., main L2R1 (note L and R are capitalized when identifying channels and their subwatersheds), followed by the sub-watershed ridge or swale line identification where lower case ‘r’ indicates a sub-watershed ridge line and a lower case ‘s’ indicates a sub-watershed swale line. The sub-watershed ridge or swale line letter is followed by a number indicating its sequential order from the head of the sub-watershed. Using this convention, the ‘main L2R1 r1’ designation identifies the first sub-watershed ridge on the right valley wall (r1) of the sub-watershed that holds the first tributary entering from the right valley wall (R1) of the second tributary entering from the left valley wall (L2) of the main channel.
