The Feature Objects Menu includes the following commands:

General Commands

  • Delete – Deletes all the feature objects in an SMS session and creates a new blank coverage (since SMS requires an active coverage at all times). SMS will ask for confirmation of this action.
  • Attributes – brings up an Attributes dialog. The specifics of the dialog are unique to each coverage.
  • Create Arc Group – This command will create a new entity from a group of selected contiguous (end to end) arcs. If the selected arcs are not connected end to end, SMS will give an error message. These arc groups can be used in some models to assign boundary conditions. This command is used to create an arc group from a continuous string of selected arcs. Once the arc group is created, it can be selected using the Select Arc Group tool. Properties can be assigned to the arc group as a whole, and the arc group can be selected to display the computed flow through the arc group. An arc group is deleted by selecting the arc group and selecting the DELETE key. Deleting an arc group does not delete the underlying arcs.
  • Build Polygons – While most feature objects can be constructed with tools in the Tool Palette, polygons are constructed with the Build Polygons command. Since polygons are defined by arcs, the first step in constructing a polygon is to create the arcs forming the boundary of the polygon. After forming loops with arcs, choose Feature Objects | Build Polygons from the menu. The build polygons command will form polygons from all closed loops in the coverage.
  • Clean
  • Vertices ↔ Nodes – In some cases, it is necessary to split an arc into two arcs. This can be accomplished using the Vertex ↔ Node command. Before selecting this command, a vertex on the arc at the location where the arc is to be split should be selected. The selected vertex is converted to a node and the arc is split in two. The Vertex ↔ Node command can also be used to combine two adjacent arcs into a single arc. This is accomplished by converting the node joining the two arcs into a vertex. Two arcs can only be merged if no other arcs are connected to the node separating the arcs. Otherwise, the node must be preserved to define the junction between the branching arcs.
  • Reverse Arc Direction – Reverses the direction of all selected arcs.
  • Redistribute Vertices – Automatically creates a new set of vertices along a selected set of arcs at either a higher or lower density.
  • Transform Feature Objects – Brings up the Transform Feature Objects dialog where data can be scaled, translated, or rotated.
  • Select/Delete Data... – Requires that one or more polygons be selected. Brings up the Select/Delete Data dialog.
  • Find – The Find... feature object command allows finding a feature object node, arc or polygon by its specified ID number.
  • Map → 2D Mesh
  • Map → 2D Grid
  • Map → Scatter – The Map → Scatter command allows scatter sets to be interpolated from map data. Scatter points can be created from a specified source. Scatter points data can be extrapolated from feature points and vertices on arc or on feature points only on arc, feature points not on arcs or from feature polygon meshing options. The elevation source can be obtained from arc elevation, arc node and vertex elevations or from arc spacing.

  • Create Coastline – Brings up the Create Contour Arcs dialog.
  • Extract Elevations – This option is found in the Feature Objects menu, in the Map module, when SHOALS is the active coverage type. The elevation of each node and vertex along every profile arc is interpolated from the active scatter set.
