Adding a breakline

Tool(s): Breakline

To create a breakline

1. Click Breakline (How).
   

   Activate Breakline in one of the following ways

   • Menu bar: Modify Terrain Site Plan

   • Palette: Tools Change area in the following module(s):

   Digital Terrain Model

   • Configuration: Landscaping/Urban Planning Digital Terrain Model flyout
2. Click the DTM in which you want to create a breakline.
3. Click New in the Input options.
4. Click a grid point or an element on which the grid points are located, and enter the breakline using the polyline entry tools.

Notes:

• You can also create and delete breaklines in order to manually define a mesh.
• Contour lines are generally interpolated linearly in the area where the breaklines pass.
• The new breakline has precedence at the points where it intersects existing breaklines.
• Deleting a grid point on which a breakline is based will cause the breakline to be deleted, too.
• Grid points on breaklines are automatically meshed into the model. This can happen with bifurcations, for example, where the fold point is a separate grid point within an edge.
• The breakline sections that overlap are taken into consideration just once.
• Breakline are calculated internally with Freeform Slope and Slope and read directly with Import, Export Point File.
