Knowing if a story is empty?

[Anonymous]

Hello,

I want to know if a specific floor has anything in it.
In other words, a function which gives the number of elements (of any kind) in a specific floor would be a great solution for me.

Thanks

Ok, this was in a developer forum, so maybe I answered for a very different thing you wanted to know of.

All layers open. Check renovation filter to show all stages of it.
Select arrow tool. Select everything (ctrl/cmd+A)
Modify Selected (ctrl/cmd+option+T)

A dialog will show you all (selected) elements by type and count.

You could call ACAPI_Element_GetElemList with the API_ElemFilterFlags parameter set to APIFilt_OnActFloor. That will extract a list of elements on the active floor - it empty, you know there aren't any.

that’s an option, but I don’t want to change the active floor every time. My goal is to make this check for every floor and then delete the layouts of floors without elements in it.

You can restore the active floor after cycling through them all.

I think the only other alternative is iterating through all the elements and checking which floor they're on. You can use ACAPI_Element_GetHeader to avoid loading the whole element.
