Hello, i have problem with curved surface in Rhino 7, they seem strange both in shaded and rendered mode. It generally happens when i use trim or fillet commands. What can be the problem or is it a real problem?
Thank you!
tools>options>mesh>smoother and slower.
if that does not clean it up enough do the same, but choose custom and set the mesh to a higher density. this is simply a display artifact, and has nothing to do with your surface quality.
Hi Kyle, thank you very much for your respond. If it doesnt effect the surface quality then it is fine. It might because of my computer performance then since i have very lower performance then rhino 6 in rhino 7.
run the systeminfo command in rhino and paste the results here

both video drivers are quite old. try updating them first.
They are latest unfortunately.
How far away is that surface from the origin?
This shouldn’t be the cause of any visual quality issues. You might want to update to 7.2 which is available as a release candidate to see if performance for your models improves.
It is 10.2 mm away from the orgin.Yes maybe it is a bug or something.
This setting is reduce the variation but there is still some.
This will help you understand it:
Additionally, it’s time to retire that old computer. It would have run V5 Rhino just fine, but it is quite inadequate for V7.
It does not meet Rhino V7’s System Requirements.
Use this guidance when choosing a replacement system:
Thanks
Okay, thank you very much!
I read it and i dont think that this is my problem or i might couldnt understand exacatly i do not know:) Even i create a cylinder without trimming or joining it. it still looks the same.
Can you share the model with us? Maybe we can figure out what is happening based on a sample 3dm
Sure, this is the file but i think it is not about the model because it happens on the cylinder that is created by cylinder command dircetly.

I think the best thing to do is buying new computer:)
@karakusc did you perform Kyle’s recommendation? I can see the display mesh is jagged in your attached model and it cleaned itself up once I made the changes that Kyle recommended.
Yes i have done that but as i said at the above, it didnt dissapper completely, just decreased.
We have to generate a mesh for a surface in order to display it on the screen. A mesh is a bunch of triangles which will never be exactly the same as the surface definition, but hopefully close enough that you won’t visually be able to tell.
The age of your computer and your display drivers are not at fault in this case.
So there is nothing to do and this is not an issue?
