Section Boxes in Grasshopper

Here’s a demo of a script we’re using to create section boxes in Grasshopper similar to those in Revit. This doesn’t split geometry but helps with animating or managing a large file in your viewport.

The section box script is similar to Luis Fraguada’s clipping plane script, except this script’s input is a closed brep and uses Python.

Rhino will limit the number of clipping planes in a viewport to 10.  The script will work on any closed brep with 10 or fewer faces.  It can also be quickly edited to work with planes. Enjoy!

    Hi there, this looks great! Thanks for sharing.

    For some reason, when I select a box as the geometry and it starts, all geometry disapears, both in and out of the box… any ideas of what I might be doing wrong?

    Thanks!

    BM, try turning the boolean toggle to “false”, select the section box, and then turn the boolean toggle to “true”, Does that work for you?
