See the attached images.  We're in 2018.

We've run an audit to no avail.  We have two files with two buildings of similar, curvilinear design.  In one, the perspectives look like the attached and in the other, they're fine.  

We are purging now, but I don't think that's going to fix anything an Audit wouldn't fix.  

Any input is appreciated.

it is a bit hard to tell from the low rez image what the problem is.what can happen in revit is when you place a camera and look through the camera window, sometimes the user wants to see more, so they select the crop window boundary and they make the view larger. They also may pivot or walk forward the camera view. These changes to the original camera view can cause distortion. If you think that is problem, then just place another camera into the same location and delete the old one.

When you post an image like this, you need to point out what you think is incorrect.  Also, that image is very small.

The image is true to how it appears in Revit -- like a low resolution image with shredded lines, things showing up in the background that should not be there, etc.  

It is not an overstretched perspective view.

See the attached images, with some of the Revit interface included.

Could be many things:Is your hardware up to spec? Does it meet Autodesk's minimum requirements?Have you tried hardware acceleration on/off?Is your GPU powerful enough?Why don't you use Enscape3D?

We have another file with a very similar building that has not given us any problems.  

We took this model and copied it into a new file and can create the 3d views with no problem.  

Our computers are above and beyond the Revit requirements.  

We tried the Hardware Acceleration possibility to no avail.  

Graphics memory is 4095 -- Quadro FX 580, though being that we were able to view the model fine in perspective when copying and pasting it into another file, it's not a graphics card issue.  

We don't have Enscape installed, but we're not trying to render.  We're just trying to get black and white perspectives.  

I can only conclude that this is a corrupt file issue, but I've never seen a corruption manifest like this.  I just hope it's not a 2018 hallmark.

FYI, your GPU does not appear to be on the list of approved GPUs. See this link. http://usa.autodesk.com/adsk/servlet/syscert?id=18844534&siteID=123112&

The complexity of the 3D view is not significant. That is, you aren't interested in textures, shadows etc, only the conceptual forms. So its not like the view is likely to cause great strain.But nonetheless fundementally, if a 3D view is not generating correctly and its not a "overstretched perspective view" then its likely to be a hardware issue.Do you have the latest Service Pack install for Revit 2018? I think its already at 2018.2.Moving forward, I suggest placing a link to your model here and I will test it on my PC.

He already mentioned no problem when transfered to new file so hardware problem not likely. I remember we 

jhad similar problem at the company i used to work for. Interestingly the model involved quite a bit of curved geometry as well.
