3 Select the polyline.
The following prompt is displayed:
Enter number of intermediate points <0>:
4 At this prompt, enter a number of intermediate points between the polyline
vertices and the daylight points using one of the following methods:
n
Type the number of points between the vertex and daylight point, and press
ENTER.
n
Type 0 to place just the daylight point, and press ENTER.
For each vertex, you are prompted for the number of points to insert.
NOTE
If you cannot see the points on screen, then make sure that you have
selected the Insert to Drawing as Created check box in the Point Settings
dialog box.
The following illustration shows how points are added between polyline vertices
and daylight points:

Creating Breaklines Between Vertices and
Daylight Points
To create a more accurate surface with the daylight information, you can create
breaklines that project from the polyline vertices to their associated daylight
points for a selected surface. This command creates a breakline for each vertex
that has a calculated daylight point. The surface to which the breakline data will
be sent must already exist within Terrain Model Explorer, but does not have to
be built.
To create daylight breaklines
1 Use the Create Multiple or Create Single command to calculate daylighting for a
polyline using multiple or single slopes.
For more information, see Calculating Daylight Points Based on a Single Slope
and Calculating Daylight Points Based on Multiple Slopes in this chapter.
2 From the Grading menu, choose Daylighting
ä
Daylight Breaklines to display
the Select Surface dialog box.
3 Select the surface name to send the daylight breakline data to, and click OK.
