3D Model Selection Tool

[CastroCardoso]

Hello, folks.

I have a minor question regarding the selection tool on 3D models that I couldn't find the solution on the user manual.
I'm currently developing a project where we measure the area and volume of coral colonies using Metashape. To do this, I need to isolate the colony from the rest of the community by selecting and deleting some elements of the overall model.

The question is: when I select part of the model, everything behind it also gets selected. I would like to be able to select only the visible part of the model that I am currently selecting.

Also, is it possible to use the tool Measure Area and Volume on a selected part of the model? Or it's always going to calculate the whole area?

Thanks in advance!
