Delete Redundant Tunnel Data

Use this dialog to delete redundant manual tunnel data, meaning data that is exactly the same or nearly the same (based on the specified tolerance).

Where can I find the dialog?

On the toolbox, select SFI Properties..., go to the Tunnel tab, and open Manual Description. Then select Delete Redundant Tunnel Data...

What can be removed

You can remove:

  • Profiles
  • Contours
  • Layers
  • Rotations
  • Surfaces

Tolerance settings

The tolerance is specified in meters and applies to profiles and contours (distance, height, and radius). For rotations, a fixed tolerance of 0.0001 is used.

If you have chosen to delete contours, unused contours will also be removed.

Note

The function maintains the link between profiles and contours by updating the references for the deleted data.
