Revit 2015 duplicate parameters

Anonymous — Wed, 26 Nov 2014 00:05:35 GMT

Hello,

Can anyone explain why in Revit 2015 a parameter multiplies? This only occurs in Revit 2015.

See below when I snoop parameters on a sheet, the Sheet Number is listed 3 times, and some instances of that parameter are empty, which is very painfull.

Is this a bug or a very unhelpful design feature?

Yes, same here. Areas for instance in Revit 2015 have 12 parameters more then in 2014. Some of which are duplicates and are empty. Don't know what the purpose is, but it sure made me double check parameters values before doing something with them 🙂

Installed UR4 hoping to see a fix, but no...

Hello Autodesk, do you have a resolution or explanation for this phenomena?

Dear chris mckeown,

This is the expected behavior, in Revit 2015, Element.Parameters will return all the parameters the element has, including UI-invisible ones.

and Element.GetOrderedParameters() method will return UI-visible parameters, same as Element.Parameters in Revit 2014 and former version, besides these parameters are ordered with group.

Thanks

Hi Aaron,

Thank you for the reply.

I know this will be documented in the help section under new features, but can I ask why the Element.Parameters wasn't let as it was in Revit 2014 (UI-visible parameters) and the new method Element.GetOrderedParameters() included UI-invisible parameters???

It is frustrating the as a developers that I have had to change all my code, when on the surface that could have been avoided...

Dear Chris,

Thanks for your feedback, I apologize for the confusion.

As Revit has already been shipped, it might not be situable to change the design again.

But I will let developement team know about your concern, we will definitely think twice about this kind of change in the future.
