Hello everybdoy,

i’am trying to cut throug an axial turbine. I want to cut every stage at 50% mid-span. The turbine expands along the z-axsis. I tried the _Slice Along PolyLine_ filter but it won’t work. I guess _Slice Along PolyLine_ is also the wrong approach since my geometry is curved.

My approach would be something like creating a point cloud and then mapping the scalars on it.

Does anyone have an idea or approach?

Thanks,

Daxx
