Creating a File of Multiple Surfaces for Sampling
the Existing Ground Section Data
To sample cross section data from multiple surfaces, you must enable the use of
multiple surfaces and use the Select Multiple Surfaces command to create a list
of the surfaces you want to sample. This command creates a surfaces.txt file that
is used when you use the Sample From Surface command.
To create a file of multiple surfaces for sampling existing ground section data
1 From the Cross Sections menu, choose Surfaces ä Select Multiple Surfaces to
display the Multiple Surface Selection dialog box.
2 From the Select from list, select the surfaces you want to use. Use the SHIFT and
CTRL keys to select multiple surfaces. Selecting names from this list places the
surface names in the Current box.
3 To remove a surface name from the Current list, hold down the CTRL key and
click the surface name in the Select from list. Click OK to create the surfaces.txt
file that will be used with the Sample From Surface command when the use
multiple surfaces is enabled.
Sampling the Existing Ground Section Data from
One Surface
You can use the Sample From Surface command to sample the existing ground
elevations from a surface along the current alignment. After you sample existing
ground section data, you can view the existing ground cross sections by using
the View/Edit Sections command if desired.
NOTE
You can also sample existing ground data from multiple surfaces.
NOTE
Any Design Control data that already exists is not deleted when you
sample the existing ground sections, even if you are overwriting the
existing ground sections.
