Bute the node “Create 3D line” fails because, this node needs a family type that i dont have…maybe this happens because i use a german templates and s.o.
I found the below video on YouTube (It looks like the package cantains rvt/rfa files in the extra folder of the package). https://www.youtube.com/watch?v=ThsiKB8rOHg
I hope it can be of help.
—Edit—
The video mentioned above has this remark: Attention: right now it works with English Revit 2018 only!
