I have a solid part with several ports to allow air flow. I'm trying to remove as much material as possible using offset surfaces and trimming etc as shelling just doesn't work with this complexity. However it's very difficult to see the surfaces in the material even when in wireframe and impossible in opaque. I've made it transparent which helps a bit but it's still hard to see where surfaces join or exist or not.

Can we make surfaces visible in wireframe or is there an alternative?
