Create tunnel templates from 3D faces - TNC3

3.6 Create Tunnel Templates from 3D Faces

This command allows to create a tunnel template file from a 3D face drawing. This file will be created in the project folder, regardless of the folder that has been selected.

To run this command, the project must contain the horizontal and vertical alignments.

The program asks for the following data:

Station interval: The distance between two tunnel templates. If this option is unchecked, the stations by interval won't be added to the final list.

Initial station: The first station of the list by interval.

Final station: The last station of the list by inteval.

Add horizontal alignment points: Allows user to add the stations of the singular points of the horizontal alignment.

Add vertical alignment points: Allows user to add the stations of the singular points of the vertical alignment.

Add extra stations: Allows user to add a station list manually o imported from a DST file. This file could be created in an easy way because it's an ASCII file with a station value per line.

The windows which manage the station list allows user to import and export DST files and, also, add and remove stations manually.

Left distance: The maximum distance, in meters, on the left of horizontal alignment which includes the elements to be analyzed.

Right distance: The maximum distance, in meters, on the right of horizontal alignment which includes the elements to be analyzed.

Replace current tunnel templates: If this option is checked, the program will replace the tunnel template file in the project and will overwrite the assignment file. Each tunnel template created will have an assignment on the station where has been calculated.

Generate tunnel templates for TcpScancyr: If this option is checked, the program will create a tunnel template file, with TRA extension, which can be imported in TcpScancyr, TcpTunnel TS and TcpTunnel Scan.

Horizontal distance to center: Negative or positive value which will be added to X component of the geometric center of each tunnel template, allowing to sort correctly the vertices generated when the tunnel template is not symmetrical.

Vertical distance to center: The same as previous parameter but the value is added to Y component of the center.
