Deleting a Range of Station Numbers

Information in this section explains how to delete a range of station numbers in a survey. Survey readings associated with the range of station numbers are also deleted. Deleting all station numbers in a survey also deletes the survey.

To delete a range of station numbers in a survey, follow these steps:

1	Click the Select ROWs button to open the Select ROWs window (Figure 7-56). Select the pipeline segment(s) with the facilities you want to work with, then click Save to close the window.

2	If the ISM module is not open, click Modules > Indirect Survey Manager (ISM).

3	Click Data Entry > Edit ISM Data to open the ISM data entry grid. Then click a button labeled with the type of continuous survey data you want to work with, such as the CIS button (Figure 7-70).

4	Select a survey folder with station numbers you want to delete. Click the down arrow in Selected Continuous Survey and select a survey folder in the selection list.

Note: If you want to collapse the Selected ROWs panel, click the Selected ROWs bar. Clicking the bar again expands the panel.
