Creating Breaklines from Figures
You can use figures located in your survey drawing, such as a centerline of a
road, edge of pavement, or centerline of a ditch, as surface breaklines. In the
process of making a surface model, you can easily select the figures to use as
breaklines. After you define breaklines, the surface triangulation follows the
breaklines by placing triangle edges coincident with the breakline segments.
Drawing the Traverse Topology/Route
You can quickly view the location of all the traverse points in your drawing
as a polygon figure. From the Analysis/Figures menu, choose Draw Traverse
Topology/Route. This command connects all the traverse points, and then
displays them as a polygon figure.
Key Concepts
■ Using the Draw Traverse Topology Route command, you can distinguish
the key set up points from the other shots on your drawing and visually
confirm the correct points are occupied.
■ You can right click on a Network Collection in the Survey Toolspace to
draw the topology.
