I am sorry...
Not for me...PartDesign_Chamfer seems sensitive to the selection order of the edges?
It does not work for me...If I first select Edge26 and then the other edges in a CCW order the command works OK.
It is not sensitive to the selection order...
My version is "Version: 0.19~pre2~201912181405~ubuntu16.04.1".
What is wrong?
