Weird Sections Appearing While Using The Chamfer Tool?

wmgallentine — Sun, 18 Jan 2026 14:06:04 GMT

I have never used Fusion 360 before, so please excuse my ignorance 🙂 I'm exporting from TinkerCAD to Fusion 360 to use the chamfer tool to add a chamfer to the top edges; however, when I add a chamfer, no matter the amount, it will add a weird section that's not supposed to be there (highlighted in blue). What's strange is that it only does it consistently on these specific ones. Does anyone know how I can fix this? Thanks!

that looks like a graphics artifact. Try setting the display detail control:

And choose "Fixed", and try different settings. Usually one will get rid of the problem.
