Floor.ByOutlineTypeAndLevel is not running

Hi everyone,
I’m making dynamo to make finishing floor from room boundary.
However when i cancel the freeze, it doesn’t responding…
What is wrong??

Thank you for your help…


Can you show the previews (under the nodes) ?

Hi @Ke2king

As @Alban_de_Chasteigner said show us all the nodes previews and also:

Thank you for your reply.
Please check as below…

Thank you for your reply.

OUT is correct.
I wanna choose rooms without PS, DS, EV, 階段(Stair).


The issue comes with your list structure under Room.FinishBoundary.

You can add a List.Flatten node with a amount of 1 after Room.FinishBoundary.

Or you can modify the list level on the input “outline” of Floor.Byoutline node

@Alban_de_Chasteigner this is not the issue. Dynamo 2.x can handle lists with sublists pretty well.

@Ke2king Could you drop here your rvt file so that we can have closer look at your issue? Or try restarting your pc it might be your PC memory issue.

Thank you…
In this case, should i reinstall dynamo?

No wait just try changing your revit version to english. See if that makes any difference. Do you know how to change to english version

I changed and tried in revit version to english.
Still it has same problem.

I change the Revit version in shortcut property, is it ok?

@Ke2king I just changed my revit version to Japanese to test if it works and it works pretty well :slight_smile:
