Grasshopper sub-D reflect?

I’ve been experimenting with sub-D’s as of late. And using grasshopper more n’ more.

I’m having a fun time with it, but have one particular simple question about the good ol’ symmetry dilemma.

See, at first I got by using “mirror” feature upon the ‘lines’ used for sub-D creation, but noticed the sub-D’s aren’t generating very good symmetry with that approach.

So, where’s the “reflection” for sub-D’s with grasshopper?


i was able to mitigate the anomaly by adding a few more lines, and using a slightly different sequence.
