'NoneType' object has no attribute 'FaceIndex'


I was generating some terrain analysis with Bison and the “flow” analysis isn’t accepting my mesh while all the other components do. It might help to say that this was a invalid mesh turned valid via CullDegenerateMeshFaces.

Hi Daniel,

I have the same problem in Rhino 7. The solution I find is to use it in Rhino 6 instead of 7. I think it is because the plug-in was not updated for new Rhino.
I hope this can help.

The issue still present

Bison is no longer maintained, so that’s not something that is going to change.
