show coinciding surfaces

[andy.engelkemier]

this would be awesome. I bet there's a way to show that, but not sure. Sometimes it's kind of subtle. But then you see what looks kind of like galvanized metal once you blow it up right? Shoot. Those surfaces are coinciding. Someone left a construction plane in the file, or smashed two things all the way together for some reason.
It would be great to get kind of an early warning of that though.

Shoot a bunch of rays, highlight areas in bright red or something like that, overlayed on top of what you're looking at. That'll let you get in there and see what's going wrong. Maybe you can just delete it, or at least you can highlight which part it is in order to head back to your modeling software to fix the issue.
