Why won't the mesh split?

[feklee]

In the Grasshopper definition below, two mesh columns are created based on the vertices of the red mesh. Then an attempt is made to split the columns using the red mesh. However, only one of the columns is split. I wonder what is the problem here. There are not many operations. So I don’t expect critical rounding errors.

If there is an alternative way to create the result, i.e. create the two split columns, that is also OK. All the ways that I can think of are convoluted. I’d like to keep things simple.

Hello
mesh splitting is better in V8 but seems to fail here. I think there was a trick in R8 to make it work better. I’ll try to find it.

I developed a little tool in Nautilus plugin to cope with R7 problems.
It cuts parts but doesn’t join the upper parts.

Thank you! I think then I go for the convoluted route of building the meshes manually.
