Select all elements at a level

i want to select all structural framing at a level. but i am not able to do so. I tried the script posted in similar forum but dynamo enter into infinite loop for that.

i am unable figure out the warning shown in figure.

Please help

in archilab package you can use node “Select.byCategoryAndLevel”. also there is one with same name in GenuisLoci package

why the list is empty.

GenuisLoci works fine with me, in your case connect Category to the right node, you are connected it to the elements

still the empty list.


Use the SelectByCateOrTypeAndLevel node instead :

The method used in the SelectByCategoryAndLevel node is faster but can’t collect certain categories (as written in the node description).
