It has come to my attention that several users have issues editing the legend in the Mechanical UI due to a graphical defect with certain NVIDIA GPUs.

How can I create a python button in Mechanical that allows me to edit the upper/lower bounds?

    Following snippet can be imported into the Button Editor to edit the legend










    Triggering the button will prompt the user to fill in the upper/lower bounds of the contour.





    The code itself is pasted below.

    import clr
    clr.AddReference("Ans.Utilities")
    clr.AddReference('Ans.UI.Toolkit')
    clr.AddReference('Ans.UI.Toolkit.Base')
    import Ansys.UI.Toolkit
    import Ansys.UI.Toolkit.Base
    
    def ChangeContours():
        try:
            
            example = ContourGUI()
            example.Run()
        except:
            ExtAPI.Log.WriteError("Exception in ChangeContours()")
        
    def GetMinMax():
        try:
            legendSettings = Ansys.Mechanical.Graphics.Tools.CurrentLegendSettings()
            noBands = legendSettings.NumberOfBands
    
    
            minVal = legendSettings.GetLowerBound(1).Value
            maxVal = legendSettings.GetLowerBound(noBands-1).Value
            return minVal, maxVal
        except:
            ExtAPI.Log.WriteError("Exception in GetMinMax()")
