Extract sections feature

[prascle]

          @prascle Hello,

I would like to request a new feature in cloudcompy - the ability to "extract sections" (https://www.cloudcompare.org/doc/wiki/index.php/Extract_Sections).

Currently, there is no easy way to do this in cloudcompy, and I believe that adding an "extract section" feature would greatly improve the efficiency and user experience of the platform. Ideally, this feature would allow users to select a section of their document or code and extract it to a new document or file, while preserving any necessary formatting, links, or other metadata.

I believe that many other users would also benefit from this feature, and I hope you will consider adding it to cloudcompy in the near future. Thank you for your continued work on this great platform!

Hello @Xu-Huitong, I'm adding it to my todo list, but I have a lot of code adaptation to do, so it probably won't be in the next version... Regards, Paul
