How to hide a category of elements on a specific level

[harry_zhao]

Hi guys as the title says.

Is there a way to hide a category of elements, say structural columns on a specific level?

To do that, I’ll have to select a category of elements at a specific level, but can’t seem to find any node to do that.

Thanks in advance.

Hi you could try SelectByCategoryAndLevel from genius loci
