in 2022 they added Temporary Structures families either model in place or as a standard family. They work fine in the current project model but if you wanted to link that project file into another project file those "temporary structures" can not be used to cut a wall in the new project. With 2026 allowing you to have walls without a core it would be nice if I could link in a model, add a wall to its face using the auto join feature, and then be able to use a TEMPORARY STUCTURE in the linked project model to cut the new all in the current project model.
For those of you confused by what feature I am talking about I am not talking about a building phase where you set it to be created and demolished in the same phase but an actually family called Temporary Structures the best example I have seen so far on its use is in the video attached jump to just before the 6 minute mark to see what I mean
