Hey,

Is this something like what you’re after?
Capture Mark Value Change _ 14-01-2019-MKA.dyn (29.9 KB)

I can’t easily test it without a rvt…

Hope that helps,

Mark

Edit: slightly updated

That I understand :wink:
But now we still have to run things to understand what goes wrong. A screenshot with the errors is usefull. Not everybody uses Structural Framings with the Mark name “TF-HCS250-010”.

So without being able to test things properly: the unlogical part is in the middle. list allindecesof. Furthermore don’t use the getparatervaluebyname as element input for setname you need the actual elements.

I want to change multiple mark values ! Getting Error !

you can’t check a list with single values.

In your case: the two mark names “HR …” is a list. Use the node List.contains.

But, what are you trying to achieve? you have a bunch of elements which you filter by mark value. and afterwards you set those specific elements to the same mark value?

== is working fine and filtering after giving multiple inputs;
Last Node isnt replacing Multiple New Values to Old Values.

I have multiple Values at Element.SetParameterByName !
How shall I give multiple Value Inputs at this node; kindly guide !
== is working fine.
I have to finally change multiple mark values by new values ;
Each Mark Value is unique

You are feeding an empty list, so it has nothing to update.

Because your == is not giving you the output you want.

18

Yeah, you are right. let me try your suggestions for ==

Mark,

How can I erase the value of Mark ? I would lie to leave that empty, they are currently pre-populated within all my Door families.

Hi Esra,

I would just feed an empty ‘string’ node to the Value input of SetParameter… I think that should work :slight_smile:

Cheers,

Mark
