I am trying to use the cut and fill component from the Bison plug in but it isn’t working. I have trying multiple methods including following youtube tutorials and every time, the component turns red with the same balloon error:
“Solution exception:Error in IEnumeratorOfTWrapper.Current. Could not cast: Rhino.Geometry.Point3f in Rhino.Geometry.Point3d”
Hi Lillian -
Bison was last updated six years ago for Rhino 6 and there is no support for it.
You should probably be looking for a different way to achieve your goal.

I don’t follow your model. I see the mesh. I gather the base rectangle is how Bison converts the mesh into a volume. I assume the curve is supposed to be a road, but I do not see a profile for the road cross section. To determine a volume you need to be able measure the difference in volume between two objects. I see a mesh and a single curve element.
I have done a bit of this, but I do not use any addons. You can easily convert that mesh into a volume. From that you can start creating whatever features you want. Provided they are solids, you can cut new parts from existing. The volume tool will tell you what you want. For better help you would need to post your model with a clear problem definition.
That’s an old plugin and doesn’t work well on Rhino 8.
Try this:
Why is this the first time I am hearing about this plugin? It is fantastic and needs some more recognition on the forums!
Cos I just wrote it in 2025 December.
There’s a cousin plugin that contains more effort:
But it is for more specific research and visualization usage for works of the research lab:
You should consider making a forum post to generate more awareness. You already seem to have good graphics on your website.
I currently don’t have time / interest for this, as this is just a side project that took me less then a month.
Thanks for the suggestion and kind words though.
Let this post live and fly for a while.
