6 At this prompt, specify the cut grade or slope for the first vertex using one of
the following methods:
n
Type a slope in the format indicated.
n
Type G and a grade.
7 Specify the fill grade or slope, using the same options in step 6.
The command calculates the daylight point for the first vertex on the polyline
you selected, and draws a temporary X to indicate the location of the daylight
point.
The following prompt is displayed:
Previous/Next/All/Indiv/Transition/eXit/Slope <Slope>:
The temporary arrow indicating the current vertex moves to the next vertex.
8 Define the cut and fill slope values for each vertex using the following options:
n
Slope: You can enter new values for both cut and fill slopes. The command
returns information about the vertex and daylight point elevations, along
with the new slope, grade, and cut or fill condition. A daylight point is then
located with an X, drawn as a temporary vector. The prompts continue and
the temporary arrow advances to the next vertex.
n
Previous: This option moves the current vertex to the previous vertex on the
polyline.
n
Next: This option moves the current vertex to the next vertex on the
polyline.
n
All: This option deletes all of the daylighting information that has been
created so far in the command process.
n
Indiv: This option deletes the daylighting information for the current vertex.
n
Transition: You can use the Transition option in areas where you want to
create a gradual transition from one slope to another between vertices. You
can use this option to set beginning cut and fill slopes from one vertex and
ending cut and fill slopes from a subsequent vertex. After you enter the
ending cut and fill slopes, the command adjusts the cut and fill slopes
automatically from the vertices between the beginning and ending vertices.
After you enter the beginning cut and fill slopes, accept the default prompt
for Next until you reach the ending vertex for the transition region. Type E
to end the transition, then enter ending cut and fill slopes. Type X to exit
back to the previous multiple slope prompts.
n
Exit: Exits the command.
9 Continue to use the options listed in step 8 to define the slope at each vertex.
10 Press ENTER repeatedly to end the command.
NOTE
The Xs that are placed in the drawing with this command indicate the
daylight points are temporary. You can use the REDRAW command to erase
them.
After the daylight match line has been calculated, you can use the Daylight
Points, Daylight Breaklines, Daylight Polyline, or the Daylight All command to
draw the daylight information in the drawing.
If a daylight point cannot be located for one or more vertices, it is because the
point cannot be found based on the vertex elevation and slope information you
