Curves do not show up in any display mode

paul.meco · January 23, 2018, 4:39pm

Hi,

I just downloaded the evaluation version of Rhino 6. I had before been using Rhino 5 and the Beta of 6 without any issues. Now, even if I start with a fresh file, curves do not display in any view mode. Surfaces show up in Render and Shade but do not have highlighted edges when selected. In Wireframe, nothing but meshes show up and they do not change color when selected.

I have tried restoring defaults for all view modes. Can anyone shed some light on this problem?

Thanks!

Hi Paul - can you please run the SystemInfo command and paste the results? I understand the 6 beta works as expected so I’m mystified at the moment… but let’s start there.

Has curves been turned off in the display ?—- Mark

Hi Mark,

No - as I said the curves are on and either way I’ve reset to default on
all views without any change - very strange.

Hi Paul - I’d look at updating the video driver asap… then let’s take it from there.

-Pascal

paul.meco · January 24, 2018, 10:55pm

Thanks Pascal - unfortunately - it appears my driver can not be updated because of a windows issue. It is a 10 year old computer. Rhino 6 works great on my work computer and laptop so - I guess it might be time to retire or upgrade that trusty old guy.

Thanks for your help!

stevebaer · January 24, 2018, 10:57pm

Try turning off GPU Tessellation in the OpenGL options page in Rhino. This feature doesn’t work very well in older drivers.

joeperezgreen · April 8, 2018, 5:28pm

Steve -

I had the same problem and your fix worked for me on a 2012 MacBook Pro running windows via bootcamp. Much appreciated.

Hi Pascal,
I have the exact same problem. Do I need to install a new video driver? Do you have any recommendations?

Hi Julia - yes… that is practically the stone age for video drivers - get the latest available driver from the nVidia wedsite, and, as this is a pretty old card, if it still does not work right, try turning off ‘GPU tessellation’ in Options > View > OpenGL page.

-Pascal

jumichals · May 14, 2018, 10:54pm

Hi Pascal - thanks! That helped bring the lines back. The only small thing is that the lines (edges) of curved objects become choppy when rotating the view.

Also, in View>OpenGL, I didn’t see any option for unchecking ‘GPU tessellation’. I will paste a screenshot.
Let me know if there’s anything else I can do!
Julia

pascal · May 14, 2018, 10:59pm

Hi Julia - ah, OK - that is V5 - that does not have GPU tessellation. I think you’re set. I don’t think there is anything to do about the degrading edges but you can try lowering the number in Options > View > Dynamic redraw. Default is 5 frames.

-Pascal

jumichals · May 14, 2018, 11:03pm

WOOPS - I didn’t realize I still had V5 open (to export my aliases) and I was drawing in that. Ignore my last comment - sorry!

I just drew the same thing in V6 and it looks beautiful.

Hi - don’t rely on Windows telling you that the drivers are up-to-date. Please update those drivers and let us know how that goes.

sc4255 · February 17, 2019, 5:16pm

Hi Wim,

Understood. What’s the best way to do that?

Thanks,
Steve

John_Brock · February 17, 2019, 5:27pm

Here’s a driver from the middle of January:

sc4255 · February 17, 2019, 5:36pm

Thanks, John!

John_Brock · February 17, 2019, 7:10pm

Did that solve it?
We’re trying to compile a list of known good and bad drivers.
What build of Windows 10 are you running?
It will be a 4 digit number.
