I was working on a definition that would use Grasshopper to automatically place walls tags. I am using the RiR component AddFamilyInstance to located and associate the wall tag and respective walls. However, the component mentioned throws an error that reads “… direction has zero length.”
I am not sure where to start to figure out how to correct this. There are no inputs in which I can supply a line or length. I have provided an image of the setup and the file itself.
Any suggestions are much appreciated.
