Overview: The profile or cross section of the terrain straight across the surface or add a Profile Section Polyline and displays the Existing and Proposed Topographies against each other. The section line can be moved or rotated to any part of the map.

*To view larger image, right click on image and click Open Image in New Tab.- Section Line - shows the line cutting through the length of the Map, if editing a breakline, the section line shows the breakline instead.
- Shift +/- - click, hold and drag the Shift arrow to adjust the section line or use the buttons on found in the lower right to adjust.
- Rotate - click, hold and drag the Rotate arrow to rotate the section line or use the button found in the lower right to rotate.
- Red Dot - highlights the area in the Map window where the mouse pointer is located on the Profile view.
- Profile View - displays the Section Line (from Proposed Topography), in blue, against the Existing Topography, in red.
- Reference Line - dashed line represents the Reference Line, which can be added in the Profile manually by hitting right click on the Profile View > Add > Reference Line. The length, height and slopes are also shown in the box at the end of the line.
- Fitted Curve - orange line represents the Fitted Curve, which can be added in the Profile manually by hitting right click on the Profile View > Add > Fitted Curve.
- Offset Line - light blue line represents the Offset Line, which can be added in the Profile manually by hitting right click on the Profile View > Add > Offset Line.
- Mouse Pointer - when the mouse pointer is placed in the Profile View, text boxes appear showing several figures.
a. Red Text Box - displays the elevation and the slope of the Existing Topography in that section.
b. Blue Text Box - displays the elevation, slope and depth of cut (C) or fill (F) of the Proposed Topography in that section.
c. Black Text Box - displays the elevation and depth of cut (C) or fill (F) where the mouse pointer lies. - Flip - flips the direction of the profile line and profile view.
- Help - directs the user to this page.
Profile View Actions
Mouse Wheel - zooms in and out the Map Window.
Mouse Wheel button - holding the mouse wheel button and dragging a window to the right zooms in that window. Holding the mouse wheel button and dragging a window to the left zooms out.
Mouse Left Click - holding left mouse button and dragging pans the Profile View.
Mouse Right Click - shows more options and actions:
- Add Reference Line, Fitted Curve or Offset Line. See Profile View section above.
- Calculate Flow - see next section below for more details.
- Export - exports the Profile as image and may include data set.
- Report - generates a Profile report as pdf.
- Autoscale Left Axis - turn this ON to let the left axis auto-scale, otherwise turn it OFF.
- Autoscale Bottom Axis - turn this ON to let the bottom axis auto-scale, otherwise turn it OFF.
- Profile Options... - adjust the sampling space or profile direction.
Calculate Flow
This tool caclulates the flow perpendicular to the Profile or Breakline. If you drew the the profile or breakline across a river, it would calculate the flow along the river.
Appearance:
Topography: Select the reference surface where the calculation will run on.
Water Elevation (m or ft): Define the top water elevation
Manning's n: Also known as Hydraulic Roughness. See 3.4.5 Runoff Analysis for more details.
Average Slope (%): Define the average slope of the water way along the whole catchment.
Sampling Spacing (m or ft): The sampling spacing profile line that the cross section flow is calculated on.
Example:
- A profile polyline was draw across a drain.
- The cross section flow was calculated using the parameters shown above.
- The blue line on the Profile View marks the Water Elevation used in the calculations.
- The Results shows a table with average water depths, velocities and flow.
