Hello, try to delete ur 3D view and create a new one and see if helps, second try to go to options > graphics and untick "use hardware accelerations" and see if helps. Thanks

Also, check if your video card driver is up to date.

[RichConyers]

What kind of graphics card/ machine are you running?

How large is the Revit file? 

Cheers,

Can you select it? I mean my first thought is that it's part of a link or something.  e.g. Visibility and Graphics related - not graphic's driver and settings related.

VG and uncheck Imported categories. See if it disappears.

[virgilio_benedictos]

check your project base point.. it should be near to the model.

[Anonymous]

yeah, its near to project model.

Please check my system and graphic options.

@Anonymous: why is this necessarily a graphics card or graphics card settings issue? Both I and @ToanDN gave you another possible explanation above. Could you possibly acknowledge our recommendations and efforts to assist you? It would certainly incentive further cooperation for your behalf.

My first thought was it's a graphics issue and should be ruled out ASAP. I'd feel foolish if I didn't rule that out only to find out it was a graphics issue.

I see something that may or may not be the problem. The hardware acceleration is off and that is a 6G card. I'm no expert I would think that card would be more than capable of utilizing this.

If it isn't a graphics problem, do you have any idea of what is in the model that might be causing this? My first guess is topography but it is too uniform.

[barthbradley]

I noticed something in your posted image that may provide a clue: a section box.  Do you by change have a 3D wireframe AutoCAD dwg imported or linked into the project? This could be the culprit.

[RobDraw]

Could you please explain how the three are related?

I have not seen or heard of this before.

[barthbradley]

Rob,

I’m not sure they are related at all – kind of like I’m not sure that this is a graphics-related issue.

On a second inspection of jshabry’s screenshot, I noticed that a Section Box was in the view and was cropping all the model elements – except for those horizontal streaks.  I just found this odd and it reminded me of something. 

Unfortunately, I got nothing for you except this Revit Architecture Forum discussion from 2015:

Only time will tell...

If the OP ever comes back.

[barthbradley]

Rob, you know what else it looks like to me? A POINT CLOUD RENDERING! Doesn't it to you? 

Then again, it could always be a disgruntled co-worker, with a sharpie in hand, going around the office and drawing over all the computer monitor screens! Ha!

Hi,
Tried this but that won´t work unfortunately.

[RobDraw]

You've been given several suggestions. In order to find out what is going on here, you need to let us know what you have tried. In other words, you need to help us in order for us to help you.

Nope, I've already said what I thought it looks like.

This looks to me like a corrupted 3d view. That happens sometimes. Just delete the view and re-create a new default 3d view to replace it.

I don't know all of the reasons why they get corrupted like that, they just sometimes do. Deleting and replacing is a quick and easy fix. if it is happening regularly, then I would start looking at graphics cards, display drivers etc...
