Thanks @TrevorFedyna
Here is a definition cluster with TT Toolbox, which works fine.
It’s great that it will work no matter how many branches, and it’s nice to put multiple datastreams in one file. A couple of complaints about this method though, one being that this plugin hasn’t been updated in 4 years and I hope it will work with future versions of R/gh. It also means another step to convert to csv later for use in other platforms.
Another problem is visible in the disabled components – if I add the geographic offset then value ends up being rounded to the hundreds or something which is obviously not doable. I don’t know if it’s a grasshopper problem, TT, or excel – excel has a way of formatting things losing significant digits. It would be nice if I could just dump a float to an ascii decimal.
