@WillAdams Very cool study! Some of those methods would make Rube Goldberg proud, but it’s still fascinating to see so many ways to skin a cat. The “new” corner tool really is a nice implementation that simplifies the process of rounding one corner while giving you full control - and the inset/outset method that you introduced a while back is a go-to for me when I want to round all the corners.

Thanks for doing this work!


Like you that inside/outside method was an eye opener when Will shared it.

Good tutorial and the various options now available.
