About the Find Next Line Break tool

Breaks in lines can occur if the line is a sounder-detected bottom and the signal was not clear or bottom detection stopped for some reason. Any line based on a broken sounder-detected bottom line will also have breaks. Breaks can also be created in lines when they are being drawn or if the line status is set to None.

If you are using lines to exclude data for analysis or for creating regions, line breaks may be undesirable. The line-break finding tool can be used to find breaks in a line so you can fill the break in.

To find a break in a line:

  1. Select the line you are checking for breaks from the Line and Surface tool list line edit tool.
  2. Point to a ping that is left of the suspected break.
  3. On the Shortcut menu (right-click), click Find Next Line Break.
    If Find Next Line Break is not displayed, no breaks exist to the right of the selected ping

The break points on a line are displayed as blue dots. If the line break is not visible, it is possible that the break is very small – try zooming in (before detecting the break) to see it.


  • You can create a break in a line by selecting a section of the line and assigning it the line status None. See About Line Status for more information.
  • You can automatically close all line breaks by creating a new line and selecting Span Gaps.
  • To clear a temporary line drawing, press ESC or on the Shortcut (right-click) menu, click Clear Line Drawing.
  • It is useful to operate in a zoomed mode when using the line break finding tool. If the scale is too large it may be difficult to see the marked gap, which may be only one ping wide.
  • You can assign a keyboard shortcut for Find the Next Line Break.
