Hello there!
I am launching Rhino 7 for the first time on my Windows PC and all drawn lines as well as the yellow selection frame around objects get only visible if I zoom in quite a lot. Is there a way to increase the thickness of all lines in my Rhino interface?
Thank you very much for your help!
Hi Kilian - can you please run SystemInfo in Rhino and copy/paste the results here? Maybe post a screen grab of a viewport as well. (Select your objects, Ctrl-C and paste in your message back.)
Like so:

Dear Pascal,
Thank you for your quick reply!

The following screenshots show the invisible lines on a normal zoom and the same lines visible on a high zoom. One line is from the selection of an imported plan and the other line is from a simple cuboid in the wireframe display.

Hi Killian- please open Options > View > OpenGL page and in there move the slider one or two notches to the left. (The Radeon drivers are problematic in Rhino and so you need to pull back that setting)
-Pascal
Dear Pascal,
Thanks for your help! Unfortunately I still have the same problem. Now the points at the edges of polylines are visible but the lines in between are still too thin. Also the selection frame did not change in thickness at all.

Hi Killian - Un-check âGPU Tessellationâ in the same dialog - any better?
-Pascal
Dear Pascal,
Yes, Un-checking GPU Tessellation did connect the dots with lines but now the dots themselves are invisible once I check âPrint Previewâ:
The lines seem connect correctly once turning âPrint Previewâ off but Iâd prefer to work with this setting enabled since it provides me with better visibility and lets me distinguish different lines easier.
Hi Killian - with âGPU Tessellationâ off, can you try increasing the slider again, if you have not?
-Pascal
Dear Pascal,
After restarting Rhino the problem has been solved! I kept the following settings:
The only problem I have left now is that the lines of 3D objects seem to be displayed in a low resolution making their edges quite jagged, is this a consequence I have to live with or is there a solution as well?
Hi Killian - you can try turning up the Anti-Aliasing on that page to 8x if that is available, but I am not sure it will help a lot.
@Kilian a developer here suggests running the OpenGL slider up to 3.3 and see if that looks better.
-Pascal
Dear Pascal,
Yes, it did work! Thank you so much for setting me up to start to learn Rhino, I would have not been able to solve this on my own!
-Kilian
Hi Killian- you are welcome - I am glad you have it sorted out, and no, there is no really good way to work around the driver issues weâve been seeing without some hand-holding.
