Revit 2021 Distorted Lines

[lucileaisha]

Hi,

I have been working in Revit 2021 for a few months now, on a couple of projects and have found myself battling with drawings that have distorted lines. Here's a screenshot of a model in progress:

As you can see, lines are wobbly. No matter the resolution chosen for the drawing, no matter how zoomed in or out, it's unclear and very difficult to work with. It prints fine, but doesn't display well at all on screens.

Has this happened to anyone? Can anyone suggest a solution to this problem please?

Note: the computer I am working from is new and has a very good spec.

Please help!

Go to File -> Options -> Graphics tab

Here is what mine looks like, how does yours compare? I think the issue is either here or you need to update / mess with your graphics drivers

Sometimes i have a similar error with having linked cadfiles that are extremely large in scale. Revit has a 2mile radius or something like that and then it starts to act a fool sometimes. turn on your project base point and internal origin to see if your content extremely far from it.

It looks like sketchy lines is ennabled.

You have some elements too far from the Internal Origin.  Check any CAD links or imports, they are likely the culprit.

Hi @RSomppi, thanks but it's not to do with the graphic display... it's happening to every view, even the newly created ones.

Did you check? My display changed to look pretty much like yours when I turned them on.

Hi @EATREVITPOOPCAD , thanks but this looks all normal here too.

Hi @curtisridenour , looks like it might be that. My project base point is very very very far from my project. I don't know how that happened. I cannot move the project base point more than 10miles from its startup location, so what can I do? Any ideas? All my views, site, project, and all the modelling is all set up.

I did...

off the top of my head i think you may need to unclip the basepoint and move it. but i never remember how those things work. i usually look them up here to refresh myself.

I tried manually moving the project base point (unclipped) or relocating the project (>manage > position) but both didn't work as the space between the two remained the same.

What I've ended up doing is the following: I created a new project in which I linked the initial one. I placed it onto the project base point of the new project, then I converted the link to a group (and unlinked the initial rvt file). The lines are now perfectly clear! I still have a lot of reorganising to do (views mainly) but I think it's worth it!

Thanks for pointing me in the right direction @curtisridenour.
