Hi,
In C4D, it has this iron tool that relaxes the selected faces. You can see it in action in this link: https://www.dropbox.com/s/c5y6fqpw45rf440/MYA027_iron_tool_for_maya.mp4?dl=0
The only tool I can think of that relaxes is the Sculpt Tool (Smooth/Relax Mode) but not quite the same as I need it based on face selection and with equal relaxing amount as demonstrated in the video.
Thank you for your time.
