TOOL: Section Boxes in Grasshopper
Here’s a demo of a script lmnts archiects are using to create section boxes in Grasshopper similar to those in Revit. This doesn’t split geometry but helps with managing a large file in your viewport.
This is similar to Luis Fraguada’s script (http://datable.net/animated-clipping-planes-in-rhinoceros/), except this script runs with a closed brep and uses Python.
