  4. Selection Filter dialog

  5. Use the checkboxes in the dialog to specify which boundaries can be selected. If you do NOT want a boundary type to be selectable, then clear the corresponding check box.
  6. Select OK in the dialog. You can then proceed with the editing option you selected in Step 1, and only the desired boundaries will be selectable for editing.

Typical Uses

The Selection Filter is useful when you need to edit certain boundaries, without selecting or editing other boundaries which may be adjacent or overlapping. For example, typical uses of the Selection Filter are:

  • If a Piezometric Line exactly overlaps another boundary (e.g. Material boundary), and you need to edit one of the boundaries without affecting the other (e.g. move or delete the boundary), then you may need to use the Selection Filter to specify which boundary can be selected for editing, and which boundary(s) cannot be selected.
  • If you are selecting boundaries with a selection window (e.g. to delete boundaries), then the selection filter can be used to specify which types of boundaries will be selected within the window, as described in the following example.


Let’s say a model had numerous Stage boundaries that you wanted to delete, without deleting any Excavations. You could turn "off" all boundary types in the Selection Filter except for Stage boundaries, and then select all Excavations with a window while using the Delete Boundaries option, and only the Stage boundaries would be selected and deleted.


  • The Selection Filter is automatically reset after each use, so that all boundaries are selectable, once the current operation has been completed.
  • In addition to the boundary editing options, the Selection Filter is also applicable to other RS2 options. For example, while Custom Discretizing, Adding / Deleting Distributed Loads, Adding / Deleting Liners, etc, the Selection Filter is available in the right-click menu.
  • The Selection Filter can be used at any time during the selection process. For example, if you accidentally select boundaries that you did not intend to select, you can use the Selection Filter to un-select any given boundary type, even after boundaries have been selected.

See the Selecting topic for more tips and information on selecting entities in RS2.
