Reply To: Different behaviour of the bevel tool
It seems the bevel tool’s behavior was modified at some point between Blender 2.71 (which this video was recorded with) and 2.79:
I’m not able to reproduce that behavior in 2.79. That’s a bummer. If you prefer the old behavior, you can choose to do those beveling tasks in the old version of Blender. I do this frequently when retopologizing because I like the way 2.77 facilitated a particular task.
