About Importing Superelevation Data

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.
