Stamping Coverage Attributes

The Stamping Coverage Attributes dialog will appear when creating a new stamping coverage. It can also be reached by right-clicking on the stamping coverage and selecting the Properties command.

  • Underlying Geometry – This section contains options for defining the scatter set used in the stamping process.
    • Use cutoff – Stamped features can be cut off where they intersect with a terrain surface dataset. Turn on this option to see available scatter sets can be selected from the data tree once this option is enabled. The scatter set will act as a surface to determine the cut off for the sloped banks of a stamped feature.
    • Bathymetry Type – The bathymetry of the scatter set needs be specified for SMS to know how to stamp the feature.
      • "Elevation" – The default option. Defines positive values as going up.
      • "Depth" – Defines positive values as going down.

Stamping Arc Attributes

When an arc is used to stamp a feature, the elevation of the arc is used to define the top of the feature. Cross section can be generated off of the arc to define the width of the feature.

The Stamping Arc Attributes dialog is reached by double-clicking on an arc created in a stamping coverage. It can also be reached by right-clicking on the selected arc and using the Attributes command.

The following attributes can be set:

  • Feature Name – This will be used when SMS creates stamped feature coverages and scatter sets from the stamping coverage.
  • Stamping Type – Can be set to either use the channel or the embankment.
    • "Cut Feature" – Will stamp the feature down from the surface, such as when stamping a channel or similar feature.
    • "Fill Feature" – Will stamp the feature up from the surface, such as when stamping an embankment or similar feature.
  • End Cap – Clicking the First End Cap or Last End Cap button will bring up the First End Cap or Last End Cap dialog. The first and last end cap is determined by the arc direction.
  • Centerline (CL) Profile – This section shows the nodes and vertices in the feature arc.
    • CS – Lists a cross section ID for each node or vertex along the arc. The arrow in the column next to the ID indicates when node or vertex is being edited in the '"Coss Section (CS) section.
    • Location on Arc – Shows the location of each node or vertex along the arc.
    • Elevation/Depth – Displays the bathymetry value assigned to each node or vertex on the arc. This field can be edited.
    • Constant → Elevation – Opens the Constant → Elevation. This dialog contains a field where an elevation can be specified for all points and vertices along the center line.
    • XY Series → Elevation – Opens the XY Series Editor where elevations can be entered as a curve. SMS will match the center line point or node elevation to the curve.
    • Plot CL Profile – Turning on this option will bring up a profile plot of the centerline. The profile plot can be kept open to see changes in the centerline as they are made in the Stamping Arc Attributes dialog.
  • Cross Section (CS) – This section defines how many cross section will be used to determine the width of the feature. It only shows the values for the current selected node or vertex in the Centerline (CL) Profile section. The cross section can be defined as a template, which is propagated all along an arc, or can be individually specified at each vertex in an arc. The cross section can also be defined individually for the left and right side of the arc.
    • Side – The left and right side of the feature is determined by the arc direction.
    • Distance from CL – Determines the distance from the center line for the left and right sides of each cross section.
    • Elevation/Depth – Determines the bathymetry for the left and right sides of each cross section.
    • Shoulder – One point on each side of the cross section can be specified as the "shoulder". For a channel, this would be the "toe", but the reference in SMS is the shoulder point. When the arcs representing the shoulder are created, the option is available to create an arc along this shoulder. If vertical walled structures are desired, the cross section can simply stop at the edge (shoulder). This will result in a feature arc at the edge and a scatter set for the top of the structure.
    • Maximum Distance from CL – This input specifies the maximum horizontal distance away from the centerline that the specified embankment side slope will extend. It is recommended that this value be something large enough so that the toes of the embankments will extend below the terrain surface elevations that are used as a cutoff surface. This will make the embankment and terrain surface intersection continuous without vertical gaps.
    • Specify Top Width and Single Side Slopes Opens the Top Width and Side Slopes dialog.
    • Current CS → All CS – Copies the current cross section definition to all other cross sections. This creates a uniform embankment across the entire length of the arc.
    • Plot Current CS – Turning on this option will bring up a profile plot of the current cross section. The profile plot can be kept open to see changes in the cross section as they are made in the Stamping Arc Attributes dialog.

End Cap

The Left End Cap and Right End Cap dialogs are used to determine how the feature will slop at the end of the arc. These dialogs are reached through the Stamping Arc Attributes dialog.

  • Type of end cap – Three types of end caps are supported.
    • "Guidebank"
    • "Sloped Abutment"
      • Slope – This table defines how the slope abutment should be shaped from the centerline. The distance and bathymetry will be used to define the shape of the slope.
        • Distance
        • Elevation/Depth
      • Maximum Distance from CS – Specifies how far the end cap can extend past the end cross section and still intersect with the bathymetry.
      • Plot Shape – Clicking this option will bring up a plot window showing how the slope abutment will be shaped.
    • "Wing Walls"
  • Angle

Stamp Features

When using the Feature Objects | Stamp Features menu command, the Stamp Features dialog appears. The dialog has the following options:

  • Stamping Options
    • Stamp to Scatter Set – This option will create a new scatter set which defines the elevation points for the new structure. This is named based on the stamped feature name. SMS triangulates all these points to create a surface and trims the scatter set to the extents of the stamped feature. The arcs that make up the stamped feature are converted to scatter breaklines to assist in the triangulation.
    • Stamp to Coverage – This option will create a new coverage with the defined breaks and extents of the new feature.
      • Coverage Type – This option contains a list of all available coverage types. Generally, it is recommended that the coverage type be selected to match the numeric engine that will eventually be used for the simulation.
  • Stamp to centerline arc – The centerline arc will be included in the stamped feature on the scatter set and/or coverage.
  • Stamp cross sections – All cross sections will be included in the stamped feature on the scatter set and/or coverage.
  • Stamp shoulders – All shoulders will be included in the stamped feature on the scatter set and/or coverage.
