All Elements Of Category in a Code Block

Does anyone know how to follow up the definition of a codeblock that defines categories, with the codeblock equivalent of All Elements Of Category? For instance:

[Category.ByName(“OST_Walls”);] - [“All Elements Of Category” node]

I can obviously plug this in to the “All Elements Of Category” node, but I’m looking for an all CB way of doing this. Any ideas or thoughts would be appreciated!

You can’t do it. DS currently doesn’t support that node!

Bummer. Thank you for the feedback!

As stated above, “All Elements of Category” can’t be used as a function. Tho you can do the next best thing and wrap it inside a custom node. That way you could do something like the below:

Thank you, Dimitar! I’ll take a look at applying this next chance I get.

@Ryan_C I’d have done this :slight_smile:

But what if you need to embed the AEOC node in an imperative block? :smiling_imp:

:laughing:
A solution to this is imperative, eh?

Thanks again @Dimitar_Venkov.

This method worked just fine!

However, I tryed to do it in an if-condition and it did not work.

I wrote this quite a while ago. You can actually streamline this further, by using the underlying ZT method ElementQueries.OfCategory (for Dynamo 2+). It should also work in imperative code:

Yes, it worked!

Thank you.

to get all elements of a category in code block, it works well for me like that, with flexibility with the commas:

c1 = Category.ByName(“Topography”);
ElementQueries.OfCategory(c1);
