From {L01, L03, L04, L05, L07} To {L01, L03-L05, L07}

Hello Dynamo community,

From {L01, L03, L04, L05, L07} To {L01, L03-L05, L07}

I am trying to figure out how could I convert a list with all the levels where a furniture type are to a more reduced list ommiting consecutive levels.

I want to convert a list with a lot of values to a shorter one with the first and the last value of the different secuences that are in the list. Finally the idea would be to convert this values to strings with a dash betwen the first and last value of each secuence to finally be added to a parameter in the family type and show the location of each type in the schedule.

Please let me know if I could clarify more my issue and thanks in advance!

Bests,
Sergio

Could you share a picture of what you’ve tried so far? Will help to clarify further what you’re trying to do as well

[Dimitar_Venkov]

You could use list indexing together with something like the “Flatten” command:

{x[0], Flatten(x[1…3]), x[4]};

Then proceed with a String.Join node (or two) :

An example of your list structure would help clear things up

@Sergio or something like this?

[Yna_Db]

@Sergio

let me know if I could clarify more my issue

It would indeed be clearer with a something like a schema and an illustration of what you tried so far with Dynamo

Hello guys,

Thanks for the comments @awilliams @Dimitar_Venkov. Find attached a couple of images to clarify the issue in question.
Looking forwards to your answers.

Regards,
Sergio

And @Vikram_Subbaiah and @Yna_Db, folloowing the schedule that I have with the previous Dynamo script and on the bottom the two possible ways to explain the location of the furniture that I would like to achieve.

[Yna_Db]

If I get it well, you want to gather levels names where a type of furniture is present and create a parameter value by concatenating the first and last of these names?

[Sergio]

Exactly, I want to simplyfiy my schedule to show where each type of furniture is in a more reduced way.

What I can’t figure out is how to chop a flatten list with all the levels where the family type is.

I though of a kind of conditional value in the select node to pick up and elements if the Index value [n-1] has == to the index value [n] + 1. Maybe I could chop the list in this cases to then pick up the first and the last value.

[Nick_Boyts]

Once you have your levels filtered down to integers you can group consecutive values together. Then you just need to do a little IF magic to get your levels to single values or paired mins and maxes.

Thanks so much @Nick_Boyts, I’ll read more about GetKeys and List.GroupByKey to understand how they work, Also let’s see if I figure out the magic node. But this is a great advance!
