Hi,
I corected the custom nodes.
The updated nodes can be downloaded and the old node replaced in C:\Users\%USERNAME%\AppData\Roaming\Dynamo\Dynamo Revit\2.16\packages\Genius Loci\dyf
(You need to click the Raw button and right click save as to properly download the custom node.)
I don’t have enough free time to create a Reference Lines per subCategory node right now but I noted the request.
