How to rename a constraint?

[Roy_043]

I am trying to rename a constraint in a sketch. The code below does not work somehow. How can this be done? Note that my test sketch has only 1 DistanceX constraint.

Code: Select all

for constr in App.ActiveDocument.Sketch.Constraints:
    if constr.Type == "DistanceX":
        constr.Name = "Width"

Code: Select all

sketch.renameConstraint(constraint_idx, u'new_name')
