Thank You!

Hi Yoeri,
Thank you for help. This will help me with list of System Types but then how i can connect to node for changing parameter value?
Attached is what i have created till now.
you want to set one workset for all the items in list?
No, it will be different Worksets for different System Types.
i did the comments parameter but it should work the same with worksets.
replace System 1, 2, 3 by worksets 
good luck
I think i didn’t explained correctly. See below what i am looking for.
- I like to find System Type for all different category i.e. Duct, Duct Accessories & Duct Fittings & Pipe, Pipe Accessories & Pipe Fittings.
- I like to change same parameter value for “Workset” for all Duct elements and then Pipe elements based on their System Type
@Nitesh_Panchal Then flatten the list of categories. it should work like this.
I dont have fittings, but i tested it with walls and windows and it works.
I am unable to enlarge image file. Could you send it again please.
I think it should work like this.
Look at the unique keys. i think they are always in the same order.
Set Workset-Per-System-Type.dyn (23.8 KB)
This is in case you have 3 system types.
If you dont always have 3 system types in your selection you need to add some filters to determine the amount of systems and which systems. and set worksets based on the selected systems.
Still not working 
Is it possible to set a workset by Element Set Parameter and a String?
