Hi Jesse - you should normally be able to use fillet to do those steps bundled up for you.

If you select a single curve with corners in it and run fillet, it will allow you to select corners to fillet.

You can even select the fillet shape to be a blend, and the next beta will also have a "bulge" slider that lets you tweak the shape of the blend.

That should effectively do what you show there. If you run into a situation where fillet doesn't work for this, then that would probably be a bug in fillet so please post any problems like that.

But of course it is always good to know the manual steps for things if the bundled up tool doesn't work for some reason...
