You must install the BimorphNodes package through the package manager.
These original nodes maybe helpful for you！
hey @Alban_de_Chasteigner can you please help me to create dynamo script using autocad to make walls and floors?
I was added the right package but i am facing this kind of problem, someone please help me on this script?
For the first node ( Group Parallel Lines) use the Genius Loci package.
For the second use the Spring nodes package.
i was installed both packages what you suggested me for download, but still i am not being able to solve that error.
@Mepdot thank you so much for suggestion.
