Filleting more than one corner at a time

Say I draw a rectangle and want to fillet all of the corners the same radius. Is there a way to just with 2 clicks do all of the corners at once?

enter the command option ‘rounded’

For any sort of curve with kinks you can fillet all the corners at once using _FilletCorners. If you have small segments in the curves near the kinks that will be “eaten” by the fillet, there may be some failure cases, see this thread
