Making mesh elements visible makes the model visually opaque and less busy, but some surface markers (the dotted crosses) simply disappear, making it impossible to select the right surface without a lot of effort (tracking common curves to deduce surface ID etc).

You could use Tools->Visibility to hide/show only parts of the model, or Tools->Clipping. Once you have a mesh you can also only display mesh edges, which will allow to "see through".
