Split Geometry

I have a rectangular box and I want to split it into half and output two separate geometries in grasshopper, is there a way to do it it?

I created a surface and put it in the center of the box and used command split Brep to split it into half but the output was still one geometry.
Thanks

Hi Thearak -

That should work just fine.

If it doesn’t on your end, you should provide the .gh file with any referenced geometry internalized.

The cutter surface in the middle should be larger than the box. ‘Surface | Primitive | Plane Through Shape’ (PxS) will create an appropriate cutter surface, given a plane in the correct position and orientation.

3. Attach minimal versions of all the relevant files
