About Editing Breaklines

Edit any breakline that you have defined by selecting it in the drawing. You can insert, move, and delete vertices, as well as redefine the level at a selected vertex.

Use any AutoCAD editing commands, including:

• Properties command (editing vertex levels)
• Change command
• Pedit command (graphical editing of polylines)
• AutoCAD grip editing

The surface stores an ID for each of the objects that are defined as breaklines. Therefore, if you modify any of the breakline objects using any of the mentioned commands, the surface is marked as out-of-date until you rebuild it.

Note: You can rebuild a surface automatically by toggling the check mark next to the Rebuild - Automatic menu entry available on the surface context menu in Prospector. For more information, see To Rebuild a Surface Automatically.
