Surface Sampling
Download the zip file containing the files needed for the exercise. Extract the files
to a convenient location on your hard drive before you begin. The files associated with
this exercise are compatiblewith Civil 3D 2013 and higher.
Working with surface information is the most elemental method of creating a
profile. This information can represent any of the surfaces already in your drawing, such
as an existing surface or any number of other surface-derived data sets. Surfaces can also
be sampled at offsets, as you’ll see in the next series of exercises. Follow these steps:
1. Open theProfileSampling.dwg file (or the
ProfileSampling_METRIC.dwg file for metric users) shown in Figure
7.2.
Figure 7.2: The drawing you’ll use for this exercise

2. From the Create Design panel on the Home tab, choose Profile  Create
Surface Profile to display the Create Profile From Surface dialog (Figure 7.3).

A Quick Tour Around the Create Profile From SurfaceDialog
This dialog has a number of important features, so take a moment to see how it breaks
down:
•
The upper-left quadrant is dedicated to information about the alignment. You can
select the alignment from a drop-down list, or you can click the Pick On Screen button.
The Station Range area shows the starting and ending stations of the alignment and
sets the To Sample range automaticallyto run from the beginning to the end of the
alignment. You can control it manually by entering the station ranges in the To Sample
text boxes or by using the Pick A Station buttons.
•
The upper-right quadrant controls the selection of the surface that will be
sampled as well as the offsets. You can select a surface from the list, or you can click
the Pick On Screen button. Beneath the SelectSurfaces list box is a Sample Offsets
check box. The offsets aren’t applied in the left and right direction uniformly. You must
enter a negative value to sample to the left of the alignment or a positive value to
sample to the right. You can add multiple offsets in a comma-delimited list here, for
example: -50, 25, -10, -5, 0, 5, 10, 25, 50. In all cases, whether or not you are samplingoffsets, the profile isn’t generated until you click the Add button.
•
The Profile List box displays all profiles associated with the alignment currently
selected in the Alignment drop-down menu. This area is generally static (it won’t
change), but you can modify the Update Mode, Layer, and Style columns by clicking the
appropriate cells in this table. You can stretch and rearrange the columns tocustomize
the view. The columns can only be modified in this location as they are created. Upon
returning to the Create Profile From Surface dialog, the profiles previously created will
have static values and can be changed in the Profile Properties dialog instead.

Select the Syrah Way option from the Alignment drop-down menu if it isn’t
already selected.
4. In the Select Surfaces listarea, select EG.
5. Click Add to add the centerline profile to the Profile list.
6. Select the Sample Offsets check box to make the entry box active.
7. Enter -25, 25 (or -7.5, 7.5 for metric users) to sample at the left and right right-
