Been struggling with this for awhile, and finally decided to ask for help from the experts.
I have a cylinder onto which I'd like a groove at goes across it diagonally and also vertically down the cylinder. I'm having trouble visualizing how to do it, and still have good topology.
I've tried knife, knife project, moving individual verts, etc. Something tells me there is an easier and cleaner way to do it, so that I have clean topology and no shading artifacts. Am I right?
I've added two pictures of this scenario for reference.
