Is there an addon for relaxing faces or edges that will work in 2.77

I need to smooth out some faces on a multi-curved surface. I don’t want to make them coplanar but something to average them out or relax them to make the curved faces and or edges smoother?

Thanks for any help with this.

LoopTools has a relax function. I usually just go to sculpt mode and use the smooth brush though.

Thanks Cyaoeu, I wasn’t expecting such a quick reply. Never thought of using the sculpt tools. I have Zbrush and haven’t delved much into the sculpt side of Blender.

I will look at LoopTools also. Thank you very much for the reply…and the help.

Space bar Search: Laplacian Smooth Vertex in Edit mode on selection. Look in Options.

Ok…great and thanks again Eppo. I will have to play around with that one. Seems to have an effect.
