FAQ

Hi everyone…

I am studying Dynamo.
But it is only been a few days.
So maybe my question is very poor…
Please understand me…

Anyway…
I want to know how to get list what include special text in element list…

for example…

a list have element names… Tap, Elbow, Tee, Reducer_ECC, Reducer_Con,…etc.

if then,
How I can get list what include special text “Reducer” by Dynamo?

Thanks…

Use String.Contains node from archi-lab. You will have a boolean list. You should then use FilterbyBoolMask…

Yes… Thank you very much…
But… I met one more problem…
Which node should I use to filter items beginning with special text?

For example…
here have list…
Pipe, A4X(SPP+GALV), Tap
Pipe, A4X(SPP+GALV), Tap
Tap, A4X(SPP+GALV)

if same as above, then How I can only make filter “Tap” without “Pipe”??

====================================
Resolved…
I used " List.Filter by String"
