Hey, I’ve a list of concrete elements and steel elements, but i want to run different scripts on them. If my parameter “Element material name” is “Concrete”, i want it to run script A onwards. AND DO NOT RUN SCRIPT B AT ALL! . Similarly, If my parameter “Element material name” is “Steel”, i want it …

I’d take a look at using a simple FilterByBoolMask or you can try the ScopeIf node. Is there a reason you don’t want to run two graphs?

There is no reliable way to prevent part of your graph from running. Dynamo executes everything “all at once”. You do have a few options to work around it though. Let the unused branch run and fail. You’ll have a warning, but everything will still work. Wrap the two branches inside a custom node. …

Here is how I would solve it. It might not be the most computationally efficient, but I’ve used this solution to create a script with 2 branches: [2 branch script] You may need to replace the String.Contains operation with something that suits your situation better, but either way, you can use a …

yeah @SeanP i want to gather info for only one type of element at a time, Like i want to crawl web for “Concrete” only, so I will input concrete in the string, and it will do a separate script to fetch amount of sand, aggregate and cement. But if i put “Steel”, i do other things for specs, like fi…

@Nick_Boyts 1- Running and making fail might not work, because im using export to excel in the end of both scripts, with different export options. 2- Please describe the second method, seems reasonable! 3- Yes python is a great option, but I don’t master in python :sleepy: thanks

Writing to Excel is fine. You would just check both outputs before passing that data onto Excel or use a similar condition to get the output of the corresponding material. Using a custom node is the exact same process as Option 1, you just do it inside the custom node. You just don’t get the wa…

@Frank_Loftus Wow, this seems like a solution. But what if I dont have any element from “Steel”? the B part will go all null and what will happen to the export to excel node in the end of B script? how to stop that to execute?

Got it, let me try these options.

Although a combined solution may get you where you want to go, but I would suggest looking at different graphs especially since each “branch” is doing completely different things with the elements found. I’d encourage simplicity when possible.
