Warchart won't work in families
I did prototype a quick tool to do what you need René
Just get the content of the zip file ( Warnings.pushbutton.zip )in a folder like this one in your pyrevit install (implies you have pyRevit):
%AppData%\Roaming\pyRevit-Master\extensions\pyRevitTools.extension\http://pyRevit.tab\Project.panel\ptools.stack\Family.pulldown
you might have to remove the bundle.yaml of the higher level folder you see in this picture for it to show up
after that, use the reload button in pyRevit and you should find the tool under pyRevit, Project, Family pulldown
Note: notice the pin icon at the top of the window to always keep it on top while managing the warnings
If you like what I do, you can support me
