At A Station
This method is probably the simplest. You supply the station
value, left swath width, and right swath width for each sample line you want to
place. You can specify the station value graphically by clicking a point in the
drawing, or numerically by typing the value at the command line. This method
is good if you only need to draw a few sample lines at odd locations. The sample
lines are perpendicular to the alignment.
From Corridor Stations
This method creates a sample line wherever there
is an assembly insertion on the corridor. This is a great solution when you
would like to create and display cross sections for design purposes. Of course,
one of the sources for your sample lines must be a corridor.
Pick Points on Screen
As the name suggests, with this method you click points
on the screen, in effect drawing the sample line. This is ideal for irregularly
shaped sample lines that have multiple vertices and/or aren't perpendicular to
the alignment.
Select Existing Polylines
This method yields the same result as Pick Points
On Screen, but you use it when you have already drawn a polyline representing
the path of the sample line.
Exercise 10.2: Create Sample lines
▶
If you haven't already
done so, download
and install the files for
Chapter 10 according to
the instructions in the
Introduction.
In this exercise, you'll create sample lines along the Jordan Court alignment.
1.
Open the drawing named
Creating Sample Lines.dwg
located in the
Chapter 10
class data folder.
2.
On the Home tab of the ribbon, click Sample Lines. When prompted
to select an alignment, press Enter and select Jordan Court in the
Select Alignment dialog box. Click OK.
3.
In the Create Sample Line Group dialog box, do the following:
▶
For Name, enter
Design
.
▶
For Sample Line Style, verify that Road Sample Line is
selected.
You're selecting only
the Jordan Court cor-
ridor to be sampled.
▶
For Sample Line Label Style, verify that Section Name is
selected.
▶
▶
Under Select Data Sources To Sample, uncheck all but the
second check box.
