Tunnel Layer Settings¶

Use this dialog to specify special settings for tunnel layers.

Where can I find the dialog?¶

In the toolbox, select SFI Properties..., then Tunnel - Manual Description - Settings.

Available Settings¶

You can set the following options:

Which layer to trim against
Starting point for the layer
Rotation for the layer

Procedure

Select the layer in the tunnel contour dialog.
Right-click and select Settings...
Specify the desired settings for the layer.
Click OK to save and exit the settings.

Example: Raised Shoulder with Curb¶

The example below shows how to use the settings for a raised shoulder (bankett) with curb.

Settings for tunnel layer with curb and shoulder

We use two layers: one for the curb and one for the shoulder. The curb layer should follow the tunnel's rotation, while the shoulder layer should have a fixed slope (minimum 5 ‰) and end at the tunnel wall. The layers are constructed as usual with surfaces.

Layer 101: Curb H¶

Clip against layer: (not set)
Start in: Surface in layer with Layer 0: Surface and Pcode: (defined)
Rotation: Tunnel rotation

Layer 102: Shoulder H¶

Clip against layer: Theo. 30: Tunnel
Start in: Surface in layer with Layer 101: Curb and Pcode: (defined)
Rotation: Unrotated

Note

If you want to start the layer, for example, 25 cm from a surface, you must account for this when constructing the surfaces in the layer.

Example of Surface Settings¶

Start in Surface 2.01¶

Surface settings: A = Surface, B = Distance, C = Height, D = Radius

Start in Surface 2.01 with 25 cm Offset¶

Surface settings with offset: A = Surface, B = Distance, C = Height, D = Radius
