Import superelevation data from a CSV file.

When you import a CSV file, the begin full super (BFS) and end full super (EFS) critical stations in the file represent the begin and end of the curve because the file does not contain explicit transition information. The station values in the file are used to match critical stations to the superelevation curves detected on the alignment. The imported data is always associated with a detected curve unless both the BFS and EFS are on a tangent/spiral entity. In that situation, the data becomes part of a user-defined curve.

If you import two regions that fall into one detected curve, they stay in the detected curve and will display both sets of critical station information.

When you import data that does not fall within a single detected curve, or BFS or EFS is not found in the file, a task dialog is displayed with the following options:

Ignore - imports all data that matches up with a curve but does not import data that does not match.
Accept - imports all data and forces the detection of curves based on where the BFS and EFS station values fall.
Cancel - no data is imported and the command closes.

If you choose Ignore or Accept, the event viewer displays the stations that did not get imported.

Overlap is not automatically resolved on the imported data.

After you import the data you can use the Superelevation Curve Manager to view the curve data and make edits using the Superelevation Tabular Editor and Superelevation Views.

To import a .CSV file

Important

The layout of the columns in the CSV file must match the layout of the columns in the Superelevation Tabular Editor. The layout should be in the following order:

Superelevation Region
Station
Description
Smoothing Curve Length
Left Outside Shoulder
Left Outside Lane
Left Inside Lane
Left Inside Shoulder
Right Outside Shoulder
Right Outside Lane
Right Inside Lane
Right Inside Shoulder

Click an alignment in the drawing.
Click Alignment tabModify panelSuperelevation drop-downView Tabular Editor.
In the Superelevation Tabular Editor, click .
In the Superelevation Import dialog box, click .
In the Select File To Import dialog box, navigate to the appropriate file. Click Open.

Note
If there is existing superelevation data, you receive a warning that existing data will be overwritten.
Click OK. The Superelevation Tabular Editor is populated with descriptions and values for each region.
