Hi Paul,
How can I switch safely from plugin version 19/20/21 and back?
For some projects I need exactly the same workflow in ArchiCAD 19 to get exactly the same wanted result,
So I did not switch to version 20 or 21 yet.
At this point I really need to switch to version 21, but I want to make sure that if needed I can switch back to version 19 later.
what files, folders, settings and so on.. do I need to backup for restore afterwards?
greetings, Jeroen
PS
And all the best wishes for you in 2018.
