Element Set parameter by name failed - Invalid Unit Type? - Bug?

Revit

Hi everyone,
I am trying to learn Dynamo to do a parametric pattern.
However, when I type the parameter name and connect to the name box, it says
“Warning: Element.SetParameterByName operation failed.
unitType is an invalid unit type. See UnitUtils.IsValidUnitType() and UnitUtils.GetValidUnitTypes().
Parameter name: unitType”

I was following a tutorial online.
The only difference is the video uses metric, and I’m using Imperial.

Dose anybody know what it is going on?
I would appreciate with your help.

Revit 2021
Dynamo 2.5

Thanks

Hi @junxian.poon,

I think it’s because you are trying to write values of an “instance” parameter to a list of family “types”.
So try to place a “FamilyInstance.ByFamilyType” node between your “All Elements of Family Type” and “Element.SetParameterByName” nodes.

Hi MJB-online,
Thank you for your reply.
It seems to have some other issues. Would you have any other suggestions?
I would appreciate it! Thank you.

Can you check what kind of input the “opening” parameter needs (number or text/string).

It says string in the dialog box, but it still doesn’t work when I change it to string.
Did I do anything wrong?

I apologize for the misunderstanding.
It is number.

I think you can forget my first comment. Other than that, I’m afraid I can’t help you because I don’t quite understand the error on your first picture. Maybe someone else can help. Good luck.

Thanks, I appreciate your effort.

Are you in the project environment or the family environment?

Hi JacobSmall,
I’m in conceptual mass environment. Do you know what I did wrong?
Would you like me to share the project files?

14

hello
it’s seem a bug, in Revit 2021 API the enumerations DisplayUnitType, UnitSymbolType, and UnitType have been deprecated

15

Hi, thanks for letting me know. How should I report it?

16

I can’t reproduce - can you please upload the family and graph as they currently stand?

17

Hi JacobSmall,
Thank you.
Please follow the link for the family and graph files.

Hello, please change normlizie to length to solve it
in adaptive file in properties in measurement tupe ------->segment length

19

Or you can generate a lengths variable and assign it to “setParameter by name” and then equate the normalization variable with it in currte pattern base.

I have the same problem. I´ve seen in tutorials that they make a python code to set parameter by name but they dont show the code. If someone coul please share that python code would be amazing
