How to close the cross section?
Due to the water in the tunnel, I cannot measure the bottom of the tunnel.
The cross profile is not closed.
For this reason, Profile Comparision does not work (deviations and areas are not calculated).
How to close such a section?
(I am attaching a screenshot.)
To close cross-sections you need to activate the checkbox Close cross-sections within the command TcpTunnel > Calculate cross-sections.
