Half-Round Trim on Armor Trying to add a half round trim around the front surfaces of a piece of modeled armor. Found videos on using inset and extrusion, but I cant figure out how to profile the extrusion into a half circle:

Alternatively, I've tried shrinkwrapping a half round pipe to the surface, but cant figure out how to make it follow the edge without meticulously rotating curves to follow the edges:

Feel like there has to be a better way to do this. Any feedback would be great!
It's a bit hard to tell what you want to do, but It sounds like you want to make a round &quot;border&quot;. In that case, Beveling is the tool for the job.
Select an edge that you need to round, and press CtrlB. Move your mouse to control the depth of the bevel, and scroll to adjust the segments of the bevel, sort of like its resolution. There are a lot of settings that you can change. You can even bevel multiple edges at the same time by selecting them all and doing the same thing. Additionally, there is a bevel modifier that can bevel every single edge.
