  There might already be one, anyway I've cobbled up a quick maxscript (won't work as expected if there are any shared verts, obviously):
  

  struct edgeVec
  (
      obj, pts, pos, vec,
  
      fn setEdge len =
      (
          polyOp.setVert obj pts[1] (pos - len * vec)
          polyOp.setVert obj pts[2] (pos + len * vec)
      )
  )
  
  fn averageEdgeLengths obj =
  (
      local edges = polyOp.getEdgeSelection obj
      local verts = polyOp.getVertsUsingEdge obj edges
      local totalLength = 0
  
      local edgeVecs = for e in edges collect
      (
          local verts = polyOp.getEdgeVerts obj e
          local v1 = polyOp.getVert obj verts[1]
          local v2 = polyOp.getVert obj verts[2]
          local vec = v2 - v1
  
          totalLength += length vec
          edgeVec obj:obj pts:verts pos:(v1 + vec/2) vec:(normalize vec)
      )
      local len = totalLength / edges.numberSet / 2
      
      for e in edgeVecs do e.setEdge len
  )
  
  if isKindOf selection[1] Editable_Poly do
      averageEdgeLengths selection[1]

  Hello !
  
  All in the title,
  do you know a script that perform this operation:
  I do a Edge Ring > Transform the lengh of the edges to have all the same length.
  
  Indifferently in Max or Maya.
  
  Thanks !

  
  I have made Set Edge Length a whyle ago - watch[ame="http://www.youtube.com/watch?v=d9aSsBe6PV4"] this video[/ame].
  I have to update it when I have spare time.

  and in case you wanted it for maya too:
  

  import maya.cmds as cmds
  from pymel.core.datatypes import Vector
  
  class edgeVec:
      def __init__(self, pts, pos, vec):
          self.pts, self.pos, self.vec = pts, pos, vec
  
      def setEdge(self, length):
          move = lambda vert, pos: cmds.move(pos[0], pos[1], pos[2], vert, ws=True, a=True)
          move(self.pts[0], self.pos - length * self.vec)
          move(self.pts[1], self.pos + length * self.vec)
  
  def getEdgeVerts(edge):
      return cmds.ls(cmds.polyListComponentConversion(edge, toVertex=True), flatten=True)
  
  def getEdgeVertsPos(edge):
      verts = cmds.xform(edge, query=True, translation=True, ws=True)
      return (Vector(verts[0:3]), Vector(verts[3:6]))
  
  def averageEdgeLengths():
      edges = cmds.filterExpand(expand=1, selectionMask=32)
      totalLength = 0.
      edgeVecs = []
  
      for e in edges:
          verts = getEdgeVerts(e)
          v1, v2 = getEdgeVertsPos(e)
          vec = v2 - v1
          length = vec.length()
  
          totalLength += length
          edgeVecs.append(edgeVec(verts, v1 + vec/2, vec/length))
  
      length = totalLength / len(edges) / 2
  
      for e in edgeVecs:
          e.setEdge(length)
  
  averageEdgeLengths()

  Thanks Swordslayer and Miauu for your precious help and your promptness !
  
  Swordslayer:
  The 3dsMax and Maya Script work like a charme.
  
  Miauu:
  I take a look to your scripts pack, the ability to setup a lenght greatly interested me.
  
  To me the perfect stitching and strap from my retopo !
