Various R8 troubles, jagged edges/curves, selection issues, trimming


I have upgraded to Rhino 8, but am still working in 7 because of some issues.

Firstly, I have the issues with the jagged edges. So far I have not seen a solution for it, is anyone aware of any?
Secondly, which is more annoying, I often cannot select surfaces in shaded. Only by clicking an edge or isocurve. This also affects trimming in the sense that it often does not trim to a surface, but I have to intersect and use generated curves to trim.

Hopefully some minor issues!

Thanks in advance,

I was hoping to get some response here, it was recommended by the reseller.

Any tips on how to get feedback?

Hi MG,

We’ll need more information to be able to help, can you post your Rhino SystemInfo as well as an example file? Thanks
