Hi!
I'd like to suggest adding in the Revit API the possibility to edit the vertical profile of walls.
Currently, it is only possible to build a wall from a vertical profile, but it is not possible to edit the vertical profile of an existing wall.
In the post below I give details of the problem:

Since Revit 2016, I have encountered this problem and when I approached it in Revit 2019, to my surprise, this limitation is still present in the API.
Regards!
