Element.SetParameterByName operation failed. The parameter is read-only

Hello friends, I’m trying to modify the slop value of each pipe in the list. But the dynamo is showing the warning, would appreciate if someone shed some light. I’ve searched on the internet already but I’m not getting its solution. Appreciate the help. Thank you

Hi @imaliasad

You can’t set slope unfortunately it is red only parameter :frowning:

Hi thanks @Kulkulf for shedding some light on the issue. Can I disable the read-only property? Is there any way to achieve the slope functionality? Thanks

Unfortunately you can’t. However you can add slope in your Geometry before you create pipes in Revit.


Thank you so much, really appreciate your help. Stay blessed : -)

@kulkul In the above picture, slope is the value ‘50’ right?
