Hi everyone, i am having troubles with curved surfaces, generated for example with loft or sweep option: the result is not a smooth surface as I would expect.
Can please someone help me? I am getting crazy with this, also tried to change mesh render quality, but the problem is still there
Can you post an example file ? Please run the Rhino command _SystemInfo and post the results here.
Here there are infos about driver…
OpenGL Settings

Redraw scene when viewports are exposed: On
Anti-alias mode: 4x

If you look the surface close in render or arctic mode you should see glitches as in the photo i posted

thanks a lot
this is an artifact due to the way the render mesh is triangulated. Go to document properties > mesh and chose smooth& slower. Alternatively chose custom and play with the maximum edge length.
This will always affect all elements in your scene. If you want more fine grain control per object take a look at the the custom mesh settings
Ok, should work now, thanks a lot !
Just another question, is working if i set custom and change the maximum edge value to 1, but how can i save this setting as a default for the next time i will use rhino? otherwise this is strange to me
Probably you have to save a empty file with your rendermesh settings as a template. Setting maximum edge length to 1 will result in very heavy meshes on large surfaces like a “floor” or a “wall” of some sorts.
Ok thanks, but what is the cause of this issue? Until last week my surfaces where smooth without setting those things, I just simply opened the file and started drawing.
Are there other possible solutions? Reinstall Rhino may be one of theme?
