Improved Mesh Selection in Edit Mode

I came across something (which I originally thought was a bug) with Box Selecting mesh on the object in Edit Mode.

I have two objects, icing and donut. If I am editing the icing in edit mode and I select some mesh with the box select, then it selects the mesh that I selected, but it also selects mesh on the other side of the icing as well.

Below is the video of the problem I am having:

I originally thought this was a bug, so I went ahead and made a report. You can read about it here: developer.blender.org/T94981

It turns out that it’s just how it has always been in Blender, and I was told that I could request this feature to be added to Blender.

Here is the explanation from one of the developers: “What happens is that when selecting in edit mode, Blender does not consider (or see) objects outside edit mode. So, some things that are occluded for the user are actually not occluded for Blender and so are also selected. This behavior could change, but this would need to be discussed first and the report would be a request for modified/improved behavior.”

I’m not sure if this feature has been requested before or not, but I will go ahead and request it anyways. I assumed that the Box Select would know exactly which part of the mesh I intended to select, so when something else happened, it threw me off a bit, I really hope you guys consider this and leave an upvote, thank you!

That's really weird. I'm not getting the same results in 2.93.7 using a couple of toruses since it's ignoring the blackfaces when I box select... Can you link the file?

My problem has always been with culling control while retopologizing a mesh which I suggested be expanded here to include the option to use custom culling volumes which might actually help with your problem as well:

Hi! The blend file is linked on this page: developer.blender.org/T94981

Would be great to have an option to ignore back faces from selection.
