Is it possible set the demolished phase of elements to “None” by Dynamo?
Our background: We use a different program for out cost estimations which needs an IFC-file to work with. Because of the limitations in the Revit IFC-Export we need to set up a separate demolition phase, which is obviously not ideal, but no way around that, if we want to distinguish the demolished elements in the calculation program.
To make the phase-management in Revit easier, I want to set the demolished phase automatically with dynamo.
The definition I have so far is fairly simple. I can set the demolished phase to a different phase, but I can’t set it to None. I have tried None, Null, 0, empty list. Any suggestions? Or is this one of those cases that can only by solved by python?

Wow. This forum is incredible. Works like a charm. Thanks a lot.
If someone else has a similar problem, I upload my finished definition: Phase-Mapping.dyn (21.3 KB)
I have similar issue. Because Revit won’t export elements that have “Phase Demolished” set to something to IFC file (logic is that they are demolished and won’t exist). I need to change all of them back to “Phase Demolished: none”. But I’m able to only get it working partially (not for all the elements) - using the same Python script suggested in this topic.
I have tried different ways of selecting items (all in active view and by category). Seems that it’s working in a selecting only couple of times, or in some small demo project…
