algorithmic modeling for Rhino

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 managing a large file in your viewport.

This is similar to Luis Fraguada's script (, except this script runs with a closed brep and uses Python.

I am having the same problem as Ethan.

Hello LMNTS and forum, I just found this interesting tool and upon trying it out had a result where all geometry disappears... Any advice ? Thanks

I totally agree that Make 2d or Vray (or any other engine) would be great to use with the Clipping Plane, but all I've seen work with the clipping plane is Rhino Render.  

If anyone is aware of another use, please share.

On a related note, does anyone know which rendering engines will be able to utilize such clipping planes? Also, I'm assuming that these clipping planes will not be maintained in a Make2D (though it would be amazing if it did), is that correct?

That's fantastic then.
Code somehow "hides" the rest of the model outside of bordering clipping planes?
It does not split it?

Thanks Djordje, the clipping plane should cut all rhino geometry, including meshes and GH previews.

Very nice!
The building model needs to be consisted of surfaces and polysurfaces? Or it can be some mesh model imported from let's say .3ds file into Rhino?

Cool! I hadn't noticed that you can use arbitrary planes as clipping planes!

Thanks Andrew.  Just removed the cluster so the file should work now.

I think your download is relying on a referenced cluster - I get an error when I try to load it.
