I often hit the wrong mesh edge that is on the other side. I think there is no such option to prevent this but I try:
Is there a way to not allow the selection of the mesh edges (or/and vertices points) on the other side of the mesh?
Because using the _SplitMeshEdge or _Merge2MeshFaces mesh tools, I’m selecting the wrong mesh edges or mesh vertices points occluded on the other side. Especially in Shaded View where backface mesh wires is not visible. If I use Ghost or Wireframe view mode, there is little space to work with and making the selection. Mesh density is hi.
