To create breaklines in a scatter set or mesh, use the following steps:

1. Create nodestrings/breaklines.
  1. Select the Create Breakline SMS Create Nodestring Tool.svg tool.
  2. Click along points of a common elevation, such as at a bank toe or levee crest, to connect these points in the surface.
  3. Use the Backspace key to back up if an erroneous selection is made.
  4. Double-click or press Enter key to complete the breakline.
2. Import breaklines.
  1. Breaklines can be imported as a scatter set using the File Import Wizard.
3. Force breaklines in a mesh.
  1. Use the Force Breaklines command in the Nodestrings menu.
  2. Set breakline options in the Nodestring Options dialog.
4. Force breaklines in a scatter set.
  1. Use the Force Breaklines command in the Breaklines menu.
  2. Set breakline options in the Scatter Breakline Options dialog.
