Hello Tran,

This will get you started. It doesn’t yet contain the filtering, but start playing with ‘Filter.ByBooleanMask’ and do a bit of a search on the forums for examples.

What do you mean by ‘Use all of node in Dynamo’ 🙂 ?

Do you mean learn how to use each node and what it does? This forum is great for that as there are some very helpful people. But it’s more of a trial and error type of thing.

If you mean find new nodes, there are a lot downloaded through the ‘Package Manager’ (Custom nodes) created by users of this forum generally.

Sol is correct, Dynamo is a “learn by doing” sort of tool. There are some helpful blog posts out there though that show the basics of how each node works for some of the basics.

Try using a formula node instead of ==. I’ve not had much success with that

Formula: a==b
