Revit shows "wireframe" in shaded and hidden line views

[EATREVITPOOPCAD]

I posted about this before, but now I realize it still wasn't solved.

Basically, in shaded (or even in hidden line &, etc...) this wireframe look happens. and when I zoom in on the objects it is still an issue, and it has been progressively getting worse. It only happens in this model, which we got from consultants, so I'm assuming they did something sloppily there...

Does anyone have any suggestions?

EDIT: oops wrong forum & I cant delete message but I will gladly take any suggestions

I think it's related to the rendering order or the Z-index of the outline geometries which used in graphics libraries to render object over another object even if it was totally behind/inside it,
in Revit (this case) I don't know the reason or even the solution,
but I wish to find out how to make this behavior on purpose of highlighting any element without selecting it,
Really hope to find this out
If you get a solution in the other forums, may you kindly share it with us 😄
thanks in advance ^^

So I never was able to fix the actual 3-D view where the issue was, but I was able to "brush this under the rug" to pleasantly work on the model... Basically, If I duplicate the 3-D view with detailing, the new view is completely fine... The original view still has the same issue. So I just deleted that original view... Now, this is where it gets interesting: The way I solved this made me remember that I had this issue once before when I just started using Revit about 5 years ago. Except back then, the 3-D view would slowly get more and more wireframe-like as I worked on the model, and after a certain amount of time, it was unworkable. At that point, I would duplicate the 3-D view, delete the original, and would get my new 3-D view which was perfect. However, as I would continue working on it, this new duplicated view started doing the same thing. It was a frustrating process lol... Luckily, as of right now, the model I am working on doesn't look like it's going to pull this fiasco on me again. 

What you are saying makes sense to me (Even though I am hearing about the concept you are mentioning for the first time 😅) Maybe the 3-D view becomes corrupt and the Z-index of outline geometries gets out of wack?
