Hi Burr, yes that is actually a good tip - that is the way you can currently tell if an object is a completely closed solid or not.

But I do want to make that information more easily accessible so that you can tell just by selecting an object and looking a display panel.

The other thing is that once you determine that an object is not a solid, you don't really have any way of seeing which edges on it are responsible for it not being closed off - that's the other part that Danny is talking about.
