Hello All,

Actually when i face a problem i am sure that i can find my answer in this great place with you guys.

i have an issue with working on dynamo with different languages, i make a script that will be used by our company in different countries and each one has Revit and Dynamo installed in different language, so i decided to use the built in parameter node instead (get value or set value), to not have any issue.

but actually i was trying to do this for changing the conduit size parameter by using [Archi-lab](https://forum.dynamobim.com/t/revit-2022-dynamo-2-10-package-not-showing-up-and-icons-missing/62933/7?) package node (Set Builtin Parameter), but i am not able to succeed, there are 2 nodes inside i do not know the difference, anyway when i use the first node to change the codnuit size to 16mm2 nothing happens (not working), and when i use the second node it change the conduit size but with a different value (4877 instead of 16).

i try to analyze by using (Get Builtin Parameter) i found that it is ready value 16 correctly.

then i try to change the size of conduit manually in Revit to 16m2 and i freez the set parameter nodes and only get the value to check, i found it = 0.052 not 16.

can you please tell me whats wrong here? may be it is something related to units, but i changed unit in Revit with Meter or Millimeter but it is also the same result…

A question leading to the answer: How many millimeters in 16 feet?

You’ll likely need to convert the data from project units or the prescribed unit to decimal feet.

Thank you for your reply, ok it works, but i need to do a lot of modifications in all my scripts which are actually huge.

i need first to convert the 16mm2 from milimeter to feet then put this as input value for the node Set Builtin parameter value, and if i want to get the conduit size i need to convert it again from feet to millimeter as shown below.

but are there no other way to use nodes directly working with milimeter not feet?  
i think this question need to be addressed to the package developer (Archilab)

but for the moment it is ok for me, i was stuck in this issue for 1 day, thanks alot 🙂
