Edit any breaklines that you have defined by selecting it in the drawing. You can insert, move, and delete vertices, as well as redefine the elevation at a selected vertex.
Use any AutoCAD editing commands, including:
- Properties command (editing vertex elevations)
- 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 Therefore, if you modify any of the breakline objects using any of the mentioned commands, the surface is marked as out-of-date until you rebuild it.
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 Rebuilding a Surface.
To change a breakline vertex elevation or location
- Select the breakline either graphically or by using an AutoCAD command, such as Properties Edit (Pedit) or Change.
- Perform the edit to the breakline.
If the breakline and surface definition become out-of-date, a
is displayed next to its node in the Prospector tree. - Rebuild the surface to update the breakline definition by right-clicking the surface in the Prospector tree and clicking Rebuild.
Note
You can rebuild a surface automatically by toggling the check mark next to the Rebuild - Automatic menu entry available on the surface short-cut menu in Prospector. For more information, see Rebuilding a Surface.
