1. Size function based on depth.
1. Import elevation data.
  1. Use File | Open... to open files with scatter data such as scatter point files, ASCII dataset files, binary dataset files, tabular data files, or XYZ files.
  2. Alternatively, drag and drop the file into the Graphics Window in SMS.
  3. Use the File Import Wizard to specify how to import the data.
2. Use the Data Calculator to create a size function dataset based on depth.
  1. Use the Data | Data Calculator command
  2. Using the Data Calculator, create size function dataset based on depth. Use the following equation:
3. Create mesh using the new size function dataset.
1. Create polygons in the map coverage.
Polygons are not created automatically when arcs are enclosed. To create polygons:
  1. Use the Feature Objects | Build Polygons command.
2. Specify mesh type for each polygon (pave / patch / none).
1. Select a polygon and open the 2D Mesh Polygon Properties dialog.
  1. Use the Select Poylgon SMS Select Polygon Tool.svg tool to select a polygon.
  2. Double-click on the selected polygon or use the Feature Objects | Attributes menu command.
2. Set the Mesh Type, Bathymetry Type, and Material Type for the polygon.
  1. Mesh types include Patch, Paving, Scalar Paving Density, and Constant Paving Density.
  2. Bathymetry type describes the elevation/topography source for the mesh nodes. Bathymetry types include a constant elevation value, interpolated elevation values from a scatter set, or interpolated elevation values from an existing mesh.
  3. Material types can be assigned to a polygon using materials previously created in Materials Data dialog.
3. Preview and edit the polygon mesh.
  1. Select the Preview Mesh button.
  2. Use the preview tools to edit the mesh.
  3. Set Arc Options to adjust distribution of vertices.
  4. Use Node Options to change how arcs are treated when using a patch mesh type.
3. Generate mesh from the map coverage.
  1. Select the map coverage and use the Map → 2D Mesh right-click command.
  2. Name the mesh.
  3. Review the mesh quality for the newly generated mesh.
2. Size function based on slope.
3. Size function based on curvature.
