Step 2: Completing the TRex Wizard

The results of the elevation extraction process are displayed and the results can be applied to a new or existing physical alternative.

• Results Preview Pane--This tabular pane displays the elevations that were calculated by TRex. The table can be sorted by label by clicking the Label column heading and by elevation by clicking the Elevation column heading. You can filter the table by right-clicking a column in the table and selecting the Filter...Custom command. You can also right-click any of the values in the elevation column to change the display options.
• Use Existing Alternative--When this is selected, the results will be applied to the physical alternative that is selected in the Use Existing Alternative menu. This menu allows the selection of the physical alternative to which the results will be applied.
• New Alternative --When this is selected, the results will be applied to a new physical alternative. First, the currently active physical alternative will be duplicated, then the results generated by TRex will be applied to the newly created alternative. The name of this new alternative must be supplied in the New Alternative text field.
• Parent Alternative--Select an alternative to duplicate from the menu, or select <None> to create a new Base alternative.
• Export Results--This exports the results generated by TRex to a tab or comma-delimited text file (.TXT). These files can then be re-used by Bentley SewerGEMS CONNECT or imported into other programs.
• Click Finish when complete, or Cancel to close without making any changes.
