Under Mesh Tools/ Edge Tools there is Set Edge Length. Because I have Edit Mesh Tools enabled? Anyway this is extremely helpful but when I select multiple edges, set Resize Behavior to Clockwise or Counterclockwise, doesn't matter, and try to make them all same length I end up with some edges shrinking one way and others the other way. What determines which way is clockwise and which is counterclockwise? Are there any tricks to make sure all selected edges only change length in one direction?
