I have different families for different concrete lifts. I edited a few due to some changes, and the edge lines disappeared in any given view, doesn't matter if it's Elevation, Section, Iso, whatever. These edits didn't change the height or location of the concrete lift, just joined some together (on the sides, not where the lines have disappeared). I completely redrew one family and some of the lines showed up but not all. Completely redrew another and it didn't help. I've checked that everything's lined up correctly, and the edges show just fine when the element is moved away or isolated. This is driving me nuts and the only thing I can think to do is to draw in model lines to make it look like they're there. This isn't a result of the Linework tool and I've tried using it to make the lines show up to no effect. In fact, the linework tool won't even highlight the lines that are missing. It's like Revit is completely ignoring that they're there. Any suggestions are appreciated. I'm starting to wonder if maybe it's a file size issue or something.
