Transfer data to Grasshopper from python

Working properly with event, callbacks or event-alike patterns in Grasshopper is quite a challenge…

Indeed, which has been especially true in GHPython. For reference, here’s a strategy I’ve been using lately (that has worked for me/my team at least):

What can trigger Geometry Pipeline component refreshing?

FWIW, I’ve recently had success subscribing to events using the __enter__ / __exit__ methods available in GHPython when running in SDK mode (i.e. that I picked up from Steve and Giulio over here). While there still are hiccups involved (e.g. this example recomputes on changes to layers other than the input Layer) it has been behaving as expected/intended for production. And is a quite terse/simple solution IMO: [MicrosoftTeams-image (3)] 211028_RecomputeOnRhinoEvents_00 (1).gh (4.1 KB)
