List - match wall lengths by name

Hello everyone, was wondering if i could match these two lists that I have here.

I have wall names & wall lengths but was wondering if I could combine these lists so that the wall name matches with the wall length and vice versa.

  • Wanted to know if I could separate them by level? not sure if that’s possible. Any feedback will be greatly appreciated, thanks!

Combine the two list with - List > Transpose
You would need to pull the level info and add that to the combined list or filter ahead of time. (I’d do it after.)

They are already in separate sublists for each level the way you have taken them:

This is representing the level.

Oh yea i did see that, went over my head a bit.

Is there a way i could combine all the data to match each other?

I guess maybe even make an excel sheet exporting level, wall type, and length?

You can try the List.GroupByKey node :slight_smile: I created a proxy of your graph (Don’t have the Excel file), but you can switch out my entire graph after the All Elements of Category into your graph after your Select.ByCategoryAndLevel node.

Sorry for the late reply, I haven’t touched the script for a bit. I’ve just tried this out, maybe I’m not doing it correctly but its giving me the “dereferencing a non-pointer” error.

You might have a null or empty somewhere in that list, but you also can’t use GroupByKey on sublists. You’ll need to apply (@L2) list levels to have it sort each sublist individually.

Hey Nick, thanks for the reply! I actually realized I had an issue with the “parametername” I wanted to get the length so ive changed it. It seems like now im getting the proper information I’ve wanted by using the @L2 function. Let me know if it looks correct to you, It looks like its matching to me but I need a better set of eyes on it. Thanks.

Can’t say for sure without seeing all of the outputs, but that should be the correct setup.

Thanks Nick! I have another problem haha. Not sure if I should start another topic for this.

But now that I have that information. Is there anyway I can export that to some list that can be a bit easier to read.

I’m trying to export it to excel (im sure this is probably the easiest way) but I want it to show it well.

EX:
Wall 1 Wall 2
10 12

Not sure if theres a way to do that? Again I can start another topic if needed.

Sounds like a new topic. Mark the solution for this one and start a new thread. You can always reference this thread in the new one if you need to.

Great! Thanks Nick!
