Chapter 1 Using the Grading Commands

Inserting Daylight Points, Breaklines, and

Polylines into a Drawing

You can insert daylight points, breaklines, and polylines into a drawing

simultaneously. The Daylight All command is a combination of the Daylight

Points, Daylight Breaklines, and Daylight Polyline commands.

To insert daylight points, breaklines, and polylines

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 All to display the

Select Surface dialog box.

3 Select the surface to use for the daylight breaklines and click then OK.

4 Select the polyline.

5 Enter the number of intermediate points between each vertex and daylight.

6 Select the name of the surface to send the breakline data to.

NOTE

The breaklines created with this command are not placed into the drawing.

You can import the breaklines into the drawing by using the Import

Breaklines command in the Terrain Model Explorer.
