How can I correct my geometry here?


I built a ring and I can’t manage to correct my geometry there. I attached a picture how I want it to be corrected and after that, I will apply some chamferEdge for the render. If the geometry correction is possible like in the picture, how can it be achieved? I’m intermediate with Rhino. Thanks!

You need to untrim and extend that one surface. Then carefully retrim everything. You can do that with Extend surface (smooth) command.
