Why the poll - there really is no need for it?
You have two engines to view 3D models.
The internal engine which has an option for hidden line which is what you are after.
The OpenGL engine does not have this option - only shaded or wire frame, so you will need to switch to the Internal engine to do what you want.
The other option is a 3D Document (this automatically uses the Internal engine (i.e. no textures only colours for surfaces).
Here you can over-ride the surface colours making them white to give the effect you want.
The advantage of a 3D Document is you can annotate it with text and dimensions which you can't do in a standard 3D view.
