User:Jcreer/SMS:Select Intersecting Objects

Example of the Select Intersecting Objects dialog

If a feature polygon is defined, it is possible to select nodes or elements in the mesh module or vertices in the data module that are inside or outside of the feature polygon. To access this tool do the following:

1. On a map coverage, select a polygon that defines the area to be selected.
2. Select the Feature Objects | Select Intersecting Objects command.

In the dialog that appears, select the geometry that will be used for the selection.

Select Intersecting Objects Dialog

The dialog contains the following options:

• Choose Data to Select – This section allows selecting specific data within the identified module where changes will eventually be applied. It contains the following options:
  • Feature Objects – Enables a break down of variables within the module to which changes will eventually be applied.
    • "Points" – Enables the selection of an individual, or group of specific points within the selected polygon.
    • "Vertices" – Enables the selection of an angle, or angles within the selected polygon.
    • "Arcs" – Enables the selection of an arc within the selected polygon.
    • "Polygons" – Enables the selection of polygons within the module.
  • Mesh – Enables the selection of specific components within the selected mesh to which the final selection will be applied.
    • "Nodes" – Enables the selection of node points of the desired mesh that are inside the selected polygon.
    • "Elements" – Enables the selection of specific elements within the mesh module of the selected polygon.
    • "Duplicate nodes" – Enables the selection of duplicate nodes within the mesh module of the selected polygon.
  • Scatter – Enables the break down and selection of specific components within a 2D scatter module to establish where changes will eventually be made.
    • "Points" – Enables the selection of specific points within the 2D scatter module of the selected polygon.
    • "Triangles" – Enables the selection of a single triangle, or group of triangles within the 2D scatter module of the selected polygon.
  • Cartesian grid – Allows the break down and selection of specific components within a Cartesian Grid module to establish where changes will eventually be made.
    • "Cells" – Enables the selection of cells within the Cartesian Grid module of the selected polygon.
  • UGrid – Enables the selection of specific components within a Ugrid module to establish where changes will eventually be made.
    • "Nodes" – Enables the selection of nodes within the Ugrid module of the selected polygon.
    • "Cells" – Enables the selection of cells within the Ugrid module of the selected polygon.
  • Quadtree
    • "Cells" – Enables the selection of cells within the Quadtree module of the selected polygon.
  • Boundary Treatment
    • "Ignore boundary, select by centroid." – Indicates that the components selected are outside the limitations of the boundary conditions rather they are selected by their centroid.
    • "Items intersected by boundary classified as out." – Indicates that the components selected are not included if they specifically are intersected by the boundary.
    • "Items intersected by boundary classified as in." – Indicates that the components selected are included despite any intersection by the boundary.
