I generally ignore updates for around 6 months once everything is working but will check now.
I tried the gh definition and it works now with your samples on latest rhino but for my data it does not want to. All steps till the solver and merge are OK but when I enable the merge for the data to go to solver it just freezes rhino. I tired with all branches (waited 1.5h) and only with three and the result is the same. What could be the reason for this freeze?
Here is the file I worked on: branchshelter.3dm (3.4 MB)
