This has been discussed recently in the fattener tool in Grasshopper, here:
We have been trying to do more with that tool, but currently we are a bit limited by it.
@DanielPiker is/was working on that. And @tomfinnigan (Ex-TSplines developer) provided some feedback on the topic.
Any more feedback you have on a silver for those intersections and what works/doesn’t in Fattener vs. TsPipe will be useful.
