can I the external services set for another servers than the default ones
For what purposes?
In some cases you can change the External Services - Options where you can change the target server address, however that would need to have another instance of the same services at that address for the commands to work. Each of these profiles addresses a specific system and that system provides a set of APIs that we work with to provide a solution. The addresses while they can be changed, would only benefit you in that situation, and not to create some additional services that you would like to integrate with TBC.
I would like to connect TBC with this local cadastral maps to use it in projects. I am not sure if the external services is the mune for that and dont know if it is possible.
