I've had this problem a couple of times and I haven't been able to figure out what triggers it or how to reverse it. I'm hoping someone can help.
I've built a complicated part, and somehow along the way it started showing a lot of edges that should be hidden. I'm in the Shaded with Edges view option, but it's showing stuff it shouldn't show. This is what it's displaying. I just want it to look like a normally shaded part without all the hidden lines cropping up.
I've plowed through the UI and the Googles a bit and can't find an answer. Can anyone help me figure out how to get back to the default appearance?
